Conversion:
boost::implicit_cast is now constexpr (#25).
Fixed broken links (PR#23).
Started using GithubActions CI for additional testing
Core:
boost/core/uncaught_exceptions.hpp has been modified for compatibility
with Mac OS 10.4 and older. (PR#92)
DLL:
More runtime checks for malformed ELFs in boost::dll::library_info
In boost::dll::library_info use info from .dynsym
ELF section if .symtab
is empty or missing
List protected ELF symbols in boost::dll::library_info
as they are available for import (#50)
Remove unneeded convert from wchar_t
to char on POSIX environment, thanks to Vladislav Shchapov (PR#49)

Filesystem:
Introducing Boost.Filesystem v4.
This new version of the library removes all deprecated features of
v3 and also makes a number of breaking API changes intended to make
Boost.Filesystem more compatible with std::filesystem introduced
in C++17. The differences are described in the release notes and
documentation using v3 and v4 tags and are also summarised in a separate
section. Users can select Boost.Filesystem version by defining BOOST_FILESYSTEM_VERSION macro
to either 3 or 4 when compiling their code. There is no need to separately
compile Boost.Filesystem for each library version - a single binary
supports both v3 and v4. Users should avoid using both v3 and v4
in the same application as this can lead to subtle bugs. Currently,
v3 is the default. In a future release v4 will become the default,
and eventually v3 will be removed. v4 is functional, but it is still
a work in progress and there may be breaking API changes in the future.
v4: path::filename,
path::stem and path::extension
no longer consider root name or root directory of the path as a filename
if the path only consists of those components. For example, on Windows
path("C:").filename()
used to return "C:" and path("C:\\").filename() used to return "" and
both will return an empty path now. (#88, #194)
v4: path::stem
and path::extension no longer treat a filename
that starts with a dot and has no other dots as an extension. Filenames
starting with a dot are commonly treated as filenames with an empty
extension. The leading dot is used to indicate a hidden file on most
UNIX-like systems. (#88)
New: Improved support for various
path prefixes on Windows. Added support for local device prefix ("\.")
and experimental support for NT path prefix ("??"). The
prefixes will be included in the root name of a path. Note that using
the prefixes with Boost.Filesystem v3 can lead to surprising results
(e.g. path("\\\\.\\").stem()
== "\\\\").
It is recommended to use the prefixes only with Boost.Filesystem
v4.
Reworked path::lexically_normal implementation
to eliminate some cases of duplicate dot (".") elements
in the normalized paths.
New: Added runtime detection of
the statx and getrandom system calls on Linux.
This can be useful if the syscall is present at compile time but
fails with ENOSYS
at run time (for example, in Docker containers that restrict the
syscall, even if available on the host). (#172)
New: Added support for disabling
usage of various system APIs at library build time. This can be useful
when a certain API is detected as present by the library configuration
scripts but must not be used for some reason (for example, when runtime
detection does not work on the target system). See the description
of configuration macros in the library documentationfor for more
details.
New: Added copy_options::synchronize_data
and copy_options::synchronize
options for the copy_file
operation. These options allow to synchronize the written data and
attributes with the permanent storage. These options are expensive
in terms of performance, but allow to ensure reliability of the copied
data. Note that copy_file
performed implicit data synchronization on POSIX systems since Boost.Filesystem
1.74.0. This release adds support for more platforms and disables
data synchronization by default while allowing the caller to explicitly
request it. (#186)
Added handling of EINTR
error code on POSIX systems for some system calls issued internally.
In particular, EINTR
could have been ignored on close,
which on HP-UX would result in a leaked file descriptor.
In the copy_file
implementations based on Linux sendfile
and copy_file_range
system calls, added handling of error codes indicating that a particular
filesystem does not support the system call and fall back to the
generic read/write loop. This should fix copy_file failing on eCryptFS
and possibly other filesystems. (#184)
The copy_file_range
system call is now used since Linux kernel 4.5, whereas previously
it was only enabled since 5.3. The copy_file
implementation will fall back to sendfile
or read/write loop if copy_file_range
fails to copy a given file across filesystems.
The copy_file implementations
based on Linux sendfile
and copy_file_range
system calls will not be used on filesystems that are known to contain
files with generated content. These system calls are incompatible
with such files, and copying them would result in zero-sized files.
The generic read/write loop will be used instead.
Currently, the blacklisted filesystems are: procfs, sysfs, tracefs
and debugfs.
In the copy_file
implementation based on read/write loop, increased the maximum
size of the buffer used for temporary storage and take into account
the target filesystem block size for more optimal performance.
On Windows CE, calling current_path
to obtain the current path for a process will now fail with an error
instead of returning successfully with a root path. This platform
does not support current directory. Changing the current path was
already failing similarly in previous releases of Boost.Filesystem.
In canonical, fixed
the check for a symlink referencing a directory above root, if an
earlier symlink was resolved to an absolute path with a different
root from the original path.
In canonical, added
a limit for the maximum number of symlinks that can be resolved during
the call. The limit is currently at least 40 symlinks.
On Windows, canonical
and weakly_canonical
will now use path::preferred_separator
for the root directory separator in the resulting paths. This fixes
"file not found" errors caused by Windows API not handling
generic separators in UNC paths and paths that start with the Win32
filesystem prefix ("\?"). (#87, #187)
New: Added weakly_canonical
overloads taking base
path as an argument.
On Windows, weakly_canonical
no longer fails with an error if the input path contains elements
that do not exist in the filesystem but are cancelled by a subsequent
dot-dot ("..") element. For example, weakly_canonical("C:\\a\\..") would previously fail if "C:\a"
directory did not exist. (#201)
In read_symlink on
Windows, corrected reparse point handling. The operation would return
an empty path for some mount points (for example, created by Box cloud storage driver) and
directory junction points that had empty print names. The new implementation
now parses substitute name of the reparse point and attempts to reconstruct
a Win32 path from it. (#187)
On Windows, file streams provided in boost/filesystem/fstream.hpp
will use wide character paths on libc++ versions 7.0 and higher,
when the standard library supports opening files with wide character
paths. (#181)
On Windows, creating symlinks should no longer require elevated privileges,
if Windows is configured in Developer
mode.
With some compilers, global objects used internally in Boost.Filesystem
are now destroyed after user's global destructors are called. This
allows to call Boost.Filesystem methods during the program termination
stage. In particular, this concerns the path locale that is used
for character code conversion and can be installed by calling path::imbue. The supported compilers
include MSVC, GCC and Clang, as well as other compilers that support
customizing program initialization order through #pragma
section (for MSVC-compatible
compilers) or __attribute__
((init_priority)) (for GCC-compatible compilers).
JSON:
value_to supports
TupleLike types.
value_to and value_from support std::array and similar types.
Implicit conversion operator from string
to std::string_view.
std::hash specializations for json types.
Fixed allocation errors in object
and key_value_pair.
Fixed crash when constructing array
from a pair of iterators that form an empty range.
LexicalCast:
Fixed assignment to an int of a floating point value that is out
of representable range for int.
Started using GithubActions CI for additional testing
Log:
Fixed compilation for riscv32 target. (PR#150)
Mp11:
Added mp_intersperse,
mp_split, mp_join
Multi-index Containers:

PFR:
A MurMur Hash based implementation of hash_combine() is now used
to reduce collisions count and improve quality of boost::pfr::hash_value()
Visual Studio 2017 now supported in C++14 mode (thanks to Denis Mikhailov
aka @denzor200)
Issues found by inspect tool were fixed
Fixed some warnings, including removal of extra semicolons in include/boost/pfr/detail/fields_count.hpp
(#72)
Added a compile time assert for inherited types (thanks to Denis
Mikhailov aka @denzor200)

if guaranteed copy elision is on
Fixed spelling issues
Started using GithubActions CI for additional testing
PropertyTree:
This is a maintenance release.
Extend compiler coverage in CI.
Fix Boost compatibility for CMakeLists.txt.
System:
The conversion operator from error_category
to std::error_category has been improved
and no longer requires <map>
or <mutex>.
The comparison operators of error_category
are now inline friends instead of member functions (a side effect
of the previous change.)
error_condition now
defers calling generic_category() to avoid instantiating the object
until it's actually needed.
error_condition::failed and error_condition::message
have been undeprecated, and operator
bool()
now once again returns failed().
The system category now doesn't call generic_category(), to avoid instantiating the object.
The return value of default_error_condition
changes in some cases into an error_condition
from the generic category, instead of from the system category. This
happens on POSIX when the input error_code
is from the system category and does not correspond to any errc_t value.
The interoperability of error_code
and std::error_code has been improved substantially.
It is now possible to construct boost::system::error_code
from std::error_code, and it's possible to
pass boost::system::error_code to functions taking
std::error_code&.
A stream insertion operator for error_condition
has been added.
Uuid:
Added to_chars for
writing uuid strings without allocating (PR#116)

New Libraries
Describe: A C++14 reflection
library, from Peter Dimov. Provides macros for describing enumerators and
struct/class members, and primitives for querying this information.

or _1 ==
' ' || _1 == '\t'.
Updated Libraries
Any:
Added boost::anys::basic_any - a data type with customizable
Small Object Optimization whose instances can hold instances of any

Notes for a complete list of changes.
Conversion:
boost::implicit_cast is now constexpr (#25).
Fixed broken links (PR#23).
Started using GithubActions CI for additional testing
Core:
boost/core/uncaught_exceptions.hpp has been modified for compatibility
with Mac OS 10.4 and older. (PR#92)
DLL:
More runtime checks for malformed ELFs in boost::dll::library_info
In boost::dll::library_info use info from .dynsym
ELF section if .symtab
is empty or missing
List protected ELF symbols in boost::dll::library_info
as they are available for import (#50)
Remove unneeded convert from wchar_t
to char on POSIX environment, thanks to Vladislav Shchapov (PR#49)
Started using GithubAction CI for additional testing
Filesystem:
Introducing Boost.Filesystem v4.
This new version of the library removes all deprecated features of
v3 and also makes a number of breaking API changes intended to make
Boost.Filesystem more compatible with std::filesystem introduced
in C++17. The differences are described in the release notes and
documentation using v3 and v4 tags and are also summarised in a separate
section. Users can select Boost.Filesystem version by defining BOOST_FILESYSTEM_VERSION macro
to either 3 or 4 when compiling their code. There is no need to separately
compile Boost.Filesystem for each library version - a single binary
supports both v3 and v4. Users should avoid using both v3 and v4
in the same application as this can lead to subtle bugs. Currently,
v3 is the default. In a future release v4 will become the default,
and eventually v3 will be removed. v4 is functional, but it is still
a work in progress and there may be breaking API changes in the future.
v4: path::filename,
path::stem and path::extension
no longer consider root name or root directory of the path as a filename
if the path only consists of those components. For example, on Windows
path("C:").filename()
used to return "C:" and path("C:\\").filename() used to return "\" and
both will return an empty path now. (#88, #194)
v4: path::stem
and path::extension no longer treat a filename
that starts with a dot and has no other dots as an extension. Filenames
starting with a dot are commonly treated as filenames with an empty
extension. The leading dot is used to indicate a hidden file on most
UNIX-like systems. (#88)
New: Improved support for various
path prefixes on Windows. Added support for local device prefix ("\\.\")
and experimental support for NT path prefix ("\??\"). The
prefixes will be included in the root name of a path. Note that using
the prefixes with Boost.Filesystem v3 can lead to surprising results
(e.g. path("\\\\.\\").stem()
== "\\\\").
It is recommended to use the prefixes only with Boost.Filesystem
v4.
Reworked path::lexically_normal implementation
to eliminate some cases of duplicate dot (".") elements
in the normalized paths.
New: Added runtime detection of
the statx and getrandom system calls on Linux.
This can be useful if the syscall is present at compile time but
fails with ENOSYS
at run time (for example, in Docker containers that restrict the
syscall, even if available on the host). (#172)
New: Added support for disabling
usage of various system APIs at library build time. This can be useful
when a certain API is detected as present by the library configuration
scripts but must not be used for some reason (for example, when runtime
detection does not work on the target system). See the description
of configuration macros in the library documentationfor for more
details.
New: Added copy_options::synchronize_data
and copy_options::synchronize
options for the copy_file
operation. These options allow to synchronize the written data and
attributes with the permanent storage. These options are expensive
in terms of performance, but allow to ensure reliability of the copied
data. Note that copy_file
performed implicit data synchronization on POSIX systems since Boost.Filesystem
1.74.0. This release adds support for more platforms and disables
data synchronization by default while allowing the caller to explicitly
request it. (#186)
Added handling of EINTR
error code on POSIX systems for some system calls issued internally.
In particular, EINTR
could have been ignored on close,
which on HP-UX would result in a leaked file descriptor.
In the copy_file
implementations based on Linux sendfile
and copy_file_range
system calls, added handling of error codes indicating that a particular
filesystem does not support the system call and fall back to the
generic read/write loop. This should fix copy_file failing on eCryptFS
and possibly other filesystems. (#184)
The copy_file_range
system call is now used since Linux kernel 4.5, whereas previously
it was only enabled since 5.3. The copy_file
implementation will fall back to sendfile
or read/write loop if copy_file_range
fails to copy a given file across filesystems.
The copy_file implementations
based on Linux sendfile
and copy_file_range
system calls will not be used on filesystems that are known to contain
files with generated content. These system calls are incompatible
with such files, and copying them would result in zero-sized files.
The generic read/write loop will be used instead.
Currently, the blacklisted filesystems are: procfs, sysfs, tracefs
and debugfs.
In the copy_file
implementation based on read/write loop, increased the maximum
size of the buffer used for temporary storage and take into account
the target filesystem block size for more optimal performance.
On Windows CE, calling current_path
to obtain the current path for a process will now fail with an error
instead of returning successfully with a root path. This platform
does not support current directory. Changing the current path was
already failing similarly in previous releases of Boost.Filesystem.
In canonical, fixed
the check for a symlink referencing a directory above root, if an
earlier symlink was resolved to an absolute path with a different
root from the original path.
In canonical, added
a limit for the maximum number of symlinks that can be resolved during
the call. The limit is currently at least 40 symlinks.
On Windows, canonical
and weakly_canonical
will now use path::preferred_separator
for the root directory separator in the resulting paths. This fixes
"file not found" errors caused by Windows API not handling
generic separators in UNC paths and paths that start with the Win32
filesystem prefix ("\\?\"). (#87, #187)
New: Added weakly_canonical
overloads taking base
path as an argument.
On Windows, weakly_canonical
no longer fails with an error if the input path contains elements
that do not exist in the filesystem but are cancelled by a subsequent
dot-dot ("..") element. For example, weakly_canonical("C:\\a\\..") would previously fail if "C:\a"
directory did not exist. (#201)
In read_symlink on
Windows, corrected reparse point handling. The operation would return
an empty path for some mount points (for example, created by Box cloud storage driver) and
directory junction points that had empty print names. The new implementation
now parses substitute name of the reparse point and attempts to reconstruct
a Win32 path from it. (#187)
On Windows, file streams provided in boost/filesystem/fstream.hpp
will use wide character paths on libc++ versions 7.0 and higher,
when the standard library supports opening files with wide character
paths. (#181)
On Windows, creating symlinks should no longer require elevated privileges,
if Windows is configured in Developer
mode.
With some compilers, global objects used internally in Boost.Filesystem
are now destroyed after user's global destructors are called. This
allows to call Boost.Filesystem methods during the program termination
stage. In particular, this concerns the path locale that is used
for character code conversion and can be installed by calling path::imbue. The supported compilers
include MSVC, GCC and Clang, as well as other compilers that support
customizing program initialization order through #pragma
section (for MSVC-compatible
compilers) or __attribute__
((init_priority)) (for GCC-compatible compilers).

if guaranteed copy elision is on
Fixed spelling issues
Started using GithubActions CI for additional testing
PropertyTree:
This is a maintenance release.
Extend compiler coverage in CI.
Fix Boost compatibility for CMakeLists.txt.
System:
The conversion operator from error_category
to std::error_category has been improved
and no longer requires <map>
or <mutex>.
The comparison operators of error_category
are now inline friends instead of member functions (a side effect
of the previous change.)
error_condition now
defers calling generic_category() to avoid instantiating the object
until it's actually needed.
error_condition::failed and error_condition::message
have been undeprecated, and operator
bool()
now once again returns failed().
The system category now doesn't call generic_category(), to avoid instantiating the object.
The return value of default_error_condition
changes in some cases into an error_condition
from the generic category, instead of from the system category. This
happens on POSIX when the input error_code
is from the system category and does not correspond to any errc_t value.
The interoperability of error_code
and std::error_code has been improved substantially.
It is now possible to construct boost::system::error_code
from std::error_code, and it's possible to
pass boost::system::error_code to functions taking
std::error_code&.
A stream insertion operator for error_condition
has been added.
Uuid:
Added to_chars for
writing uuid strings without allocating (PR#116)

Fixed compilation for riscv32 target. (PR#150)
Mp11:
Added mp_intersperse,
mp_split, mp_join
Multi-index Containers:
Maintenance work.
PFR:
A MurMur Hash based implementation of hash_combine() is now used
to reduce collisions count and improve quality of boost::pfr::hash_value()
Visual Studio 2017 now supported in C++14 mode (thanks to Denis Mikhailov
aka @denzor200)
Issues found by inspect tool were fixed
Fixed some warnings, including removal of extra semicolons in include/boost/pfr/detail/fields_count.hpp
(#72)
Added a compile time assert for inherited types (thanks to Denis
Mikhailov aka @denzor200)
Reflection of aggregates with non movable fields is now possible
if guaranteed copy elision is on
Fixed spelling issues
Started using GithubActions CI for additional testing
PropertyTree:
This is a maintenance release.
Extend compiler coverage in CI.
Fix Boost compatibility for CMakeLists.txt.
System:
The conversion operator from error_category
to std::error_category has been improved
and no longer requires <map>
or <mutex>.
The comparison operators of error_category
are now inline friends instead of member functions (a side effect
of the previous change.)
error_condition now
defers calling generic_category() to avoid instantiating the object
until it's actually needed.
error_condition::failed and error_condition::message
have been undeprecated, and operator
bool()
now once again returns failed().
The system category now doesn't call generic_category(), to avoid instantiating the object.
The return value of default_error_condition
changes in some cases into an error_condition
from the generic category, instead of from the system category. This
happens on POSIX when the input error_code
is from the system category and does not correspond to any errc_t value.
The interoperability of error_code
and std::error_code has been improved substantially.
It is now possible to construct boost::system::error_code
from std::error_code, and it's possible to
pass boost::system::error_code to functions taking
std::error_code&.
A stream insertion operator for error_condition
has been added.
Uuid:
Added to_chars for
writing uuid strings without allocating (PR#116)

The service that Boost uses to serve up its releases, Bintray.com is being retired
by JFrog on the 1st of May. Fortunately for Boost, they have a new service, called
JFrog.Arifactory, which we have transitioned to.
For the
... [More]
users of Boost, the only difference is that there is a new URL to download
releases and snapshots.
Instead of: https://dl.bintray.com/boostorg/release/
you should use https://boostorg.jfrog.io/artifactory/main/release/
to retrieve boost releases.
Note: The pre-1.64 Boost releases are still available via Sourceforge.
Thank you to JFrog for all your past and current support.

managed_windows_shared_memory
shared_memory_object
windows_shared_memory_object
file_lock
named_condition
named_condition_any
named_mutex

Added BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION
macro option to disable the use of generic emulation code for process
shared synchronization primitives instead of native POSIX or Winapi
functions.
Fixed bugs:
GitHub
#76 ("Cygwin compilation errors").
GitHub
#83 ("Add BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION
option").
GitHub
#92 ("bufferstream: Correct MSVC compilation
warning").
GitHub

GitHub
#120 ("segment_manager customization").
GitHub
#122 ("Mark constructors/assignment/swap noexcept
where possible").
GitHub
#126 ("_ReadWriteBarrier is deprecated warning

JSON:
Security
Report from Bishop Fox.
(#481) Refactored value_from
implementation; user customizations are now always preferred over
library-provided overloads.
(#484) Fix imprecise parsing for some floating point numbers.
(#485) Fix link errors in standalone mode, when used alongside
Boost.
(#497) Fix Boost.Build builds on GCC 4.8.
LexicalCast:
Dropped dependency on Boost.Math (thanks to Peter Dimov #37,
#39).
Fixes for the CI and coverage (thanks to Sam Darwin from "The
C++ Alliance" #38, #42).
Log:
Bug fixes:
Corrected a formal race condition in the thread-safe log record
queue implementation used in the unbounded_fifo_queue
policy of the asynchronous_sink
frontend. The race could be detected by TSAN, but it was not
a real problem on most current CPU architectures and compilers.
(#139)
When copying a logger with a channel attribute (e.g. channel_logger), the channel
attribute is now deep-copied from the original logger. This
means that modifying the channel in the new logger will no
longer affect the original logger.
Replaced the use of std::allocator<void> in template parameters
with a new tag type boost::log::use_std_allocator
to silence libc++ warnings about the former being deprecated
in C++17 and later. The tag indicates that the instantiated
template should be using a specialization of std::allocator internally to allocate
dynamic memory, so the change has no functional effect. (#141)
Boost.Log no longer defines __MSVCRT_VERSION__
macro on MinGW and MinGW-w64. Defining this macro caused incompatibility
with UCRT, which is available as an option in recent MinGW-w64.
(PR#149)
See changelog
for more details.
Math:
Breaking Change: C++03 support is
now removed, a C++11 or later conformant compiler is now required
to use this library.
Added Z-test.
Added execution policy support to univariate and bivariate statistics:
enables parallel execution (requires C++17 and <execution>).
Big update/improvement on CI testing.
Bivariate statistics now have integer support.
T-Test now has integer support.
Linear regression now has integer support.
Correct PDF of the beta distribution at the endpoints.
Correct use of Stirling's approximation in certain multiprecision
cases, fixes #396.
Eliminate -Wimplicit-int-float-conversion on clang.
Fix some constexpr issues in quaternion/octonion.
Minor performance fix to tanh_sinh integration.
Update hypergeometric functions internal scaling to allow for 64-bit
(long long) exponents with multiprecision types.
Move:
Git Issue
#35: "New nothrow move traits are incomplete".
Multiprecision:
BREAKING CHANGE: Massive refactoring
and code simplification makes C++11 an absolute requirement.
Use BOOST_TRY/CATCH in headers so code can be used in exception-free
environments.
Correct corner case in pow, fixes #277.
Correct exception type thrown to match docs in lsb/msb: fixes #257.
Allow moves and operators between related but different types (ie
types with the same allocator), fixes #278.
Nowide:
Fix discarding of characters for text file streams when seek or sync
functions are used and newlines were converted (e.g. on Windows)
Fix potential use-after-free bug when reusing (via open) a file stream that has been
closed
Fix potential invalid memory access when using a file stream that
has been moved or swapped to where the source had a put-back character
or was set to unbuffered mode
Fix compatibility with ucrt runtime by not defining __MSVCRT_VERSION__
Known issues: Read performance for text files is degraded. Binary
files and writing is unaffected.
Optional:
Fixed MSVC warning C4702.
Outcome:
Announcements:
BREAKING CHANGE: After a year and three major Boost releases
announcing this upcoming change, this is the FIRST RELEASE
of the v2.2 branch. This branch has a number of major breaking
changes to the Outcome v2.1 which shipped in Boost 1.75 and
earlier, see the documentation for details.
Enhancements:
VS2019.8 changed how to enable Coroutines, which caused Outcome
to not compile on that compiler.
If on C++ 20, we now use C++ 20 [[likely]]
instead of compiler-specific markup to indicate when TRY has
likely success or failure.
BREAKING CHANGE: Previously the value of spare_storage(const
basic_result|basic_outcome *)
noexcept was not propagated
over BOOST_OUTCOME_TRY,
which causes things like stack backtraces captured at the point
of construction of an errored result to get dropped at every
TRY point.
This has been fixed by adding an optional spare_storage
to success_type<T> and failure_type<T>, as well as to auto success(T
&&, ...)
and auto failure(T
&&, ...).
Bug fixes:
Boost.Outcome should now compile with BOOST_NO_EXCEPTIONS
defined. Thanks to Emil, maintainer of Boost.Exception, making
a change for me, Boost.Outcome should now compile with C++
exceptions globally disabled. You won't be able to use boost::exception_ptr as it can't
be included if C++ exceptions are globally disabled.
BREAKING CHANGE #244
It came as a shock to learn that BOOST_OUTCOME_TRY
had been broken since the inception of this library for certain
corner case code, which required a breaking change in how TRY
works. See the
changelog in the documentation for more detail.
Parameter:
Added a workaround for MSVC 2015 code miscompilation when an rvalue
was used as a default value of a named parameter of a function. (PR#109,
#132)
PFR:
Fixed reflection of types with missing const
in SFINAE expressions in template constructor. Now reflection of
aggregates with std::optional<std::chrono::duration??>> fields works on any
Standard Library implementation, even if LWG3050 is not fixed.
Comparison functions are now constexpr
#52
Fixed numerous typos in docs (thanks to Phil Miller #63)
PolyCollection:
Worked around GCC
bug affecting GCC versions 9.3-10.2 (issue #20).
Predef:
Version 1.13
Add ARCH_PPC_64 predef.
Fix ARCH_WORD_BITS* redefinition warnings/errors.
Add ARCH_E2K, Elbrus
2000, architecture from Konstantin Ivlev.
Fix not handling recent C++ version that go above 10.x version.
Version 1.12
Switch to using the endian.h header on OpenBSD. (Brad Smith)
Fix not handling recent versions of stdcxx that go above version
9.
Fix including sub-BSD OS headers directly causing redef warnings.
Add CI testing of direct inclusion of all headers.
Add CI testing on FreeBSD for clang and gcc.
Add WORD_BITS set
of predefs to detect the architecture word size. Initial implementation
inspired by submission from Mikhail Komarov.
Add CI testing for Cygwin 32 and 64.
PropertyTree:
Property Tree has a new maintainer.
Fix usage of deprecated Boost.Bind features.
Link to Wikipedia fixed.
Use BOOST_OVERRIDE to fix GCC warnings.
Add extensive CI testing.
Regex:
Regex is now header only except in C++03 mode.
Support for C++03 is now deprecated.
The library can now be used "standalone" without the rest
of Boost being present.
Stacktrace:
Better support for pre-C++11 builds on clang #102.
Bigger warning for do not use boost::stacktrace::stacktrace
in signal handlers #71.
TypeTraits:
Fix for Visual Studio managed code projects.
Variant2:
Improved generated code for the double buffered case.

Report from Bishop Fox.

Log:
Bug fixes:
Corrected a formal race condition in the thread-safe log record
queue implementation used in the unbounded_fifo_queue
policy of the asynchronous_sink
frontend. The race could be detected by TSAN, but it was not
a real problem on most current CPU architectures and compilers.
(#139)
When copying a logger with a channel attribute (e.g. channel_logger), the channel
attribute is now deep-copied from the original logger. This
means that modifying the channel in the new logger will no
longer affect the original logger.
Replaced the use of std::allocator<void> in template parameters
with a new tag type boost::log::use_std_allocator
to silence libc++ warnings about the former being deprecated
in C++17 and later. The tag indicates that the instantiated
template should be using a specialization of std::allocator internally to allocate
dynamic memory, so the change has no functional effect. (#141)
Boost.Log no longer defines __MSVCRT_VERSION__
macro on MinGW and MinGW-w64. Defining this macro caused incompatibility
with UCRT, which is available as an option in recent MinGW-w64.
(PR#149)
See changelog
for more details.
Math:
Breaking Change: C++03 support is
now removed, a C++11 or later conformant compiler is now required
to use this library.
Added Z-test.
Added execution policy support to univariate and bivariate statistics:
enables parallel execution (requires C++17 and <execution>).
Big update/improvement on CI testing.
Bivariate statistics now have integer support.
T-Test now has integer support.
Linear regression now has integer support.
Correct PDF of the beta distribution at the endpoints.
Correct use of Stirling's approximation in certain multiprecision
cases, fixes #396.
Eliminate -Wimplicit-int-float-conversion on clang.
Fix some constexpr issues in quaternion/octonion.
Minor performance fix to tanh_sinh integration.
Update hypergeometric functions internal scaling to allow for 64-bit
(long long) exponents with multiprecision types.
Move:
Git Issue
#35: "New nothrow move traits are incomplete".
Multiprecision:
BREAKING CHANGE: Massive refactoring
and code simplification makes C++11 an absolute requirement.
Use BOOST_TRY/CATCH in headers so code can be used in exception-free
environments.
Correct corner case in pow, fixes #277.
Correct exception type thrown to match docs in lsb/msb: fixes #257.
Allow moves and operators between related but different types (ie
types with the same allocator), fixes #278.
Nowide:
Fix discarding of characters for text file streams when seek or sync
functions are used and newlines were converted (e.g. on Windows)
Fix potential use-after-free bug when reusing (via open) a file stream that has been
closed
Fix potential invalid memory access when using a file stream that
has been moved or swapped to where the source had a put-back character
or was set to unbuffered mode
Fix compatibility with ucrt runtime by not defining __MSVCRT_VERSION__
Known issues: Read performance for text files is degraded. Binary
files and writing is unaffected.
Optional:
Fixed MSVC warning C4702.
Outcome:
Announcements:
BREAKING CHANGE: After a year and three major Boost releases
announcing this upcoming change, this is the FIRST RELEASE
of the v2.2 branch. This branch has a number of major breaking
changes to the Outcome v2.1 which shipped in Boost 1.75 and
earlier, see the documentation for details.
Enhancements:
VS2019.8 changed how to enable Coroutines, which caused Outcome
to not compile on that compiler.
If on C++ 20, we now use C++ 20 [[likely]]
instead of compiler-specific markup to indicate when TRY has
likely success or failure.
BREAKING CHANGE: Previously the value of spare_storage(const
basic_result|basic_outcome *)
noexcept was not propagated
over BOOST_OUTCOME_TRY,
which causes things like stack backtraces captured at the point
of construction of an errored result to get dropped at every
TRY point.
This has been fixed by adding an optional spare_storage
to success_type<T> and failure_type<T>, as well as to auto success(T
&&, ...)
and auto failure(T
&&, ...).
Bug fixes:
Boost.Outcome should now compile with BOOST_NO_EXCEPTIONS
defined. Thanks to Emil, maintainer of Boost.Exception, making
a change for me, Boost.Outcome should now compile with C++
exceptions globally disabled. You won't be able to use boost::exception_ptr as it can't
be included if C++ exceptions are globally disabled.
BREAKING CHANGE #244
It came as a shock to learn that BOOST_OUTCOME_TRY
had been broken since the inception of this library for certain
corner case code, which required a breaking change in how TRY
works. See the
changelog in the documentation for more detail.
Parameter:
Added a workaround for MSVC 2015 code miscompilation when an rvalue
was used as a default value of a named parameter of a function. (PR#109,
#132)
PFR:
Fixed reflection of types with missing const
in SFINAE expressions in template constructor. Now reflection of
aggregates with std::optional<std::chrono::duration??>> fields works on any
Standard Library implementation, even if LWG3050 is not fixed.
Comparison functions are now constexpr
#52
Fixed numerous typos in docs (thanks to Phil Miller #63)
PolyCollection:
Worked around GCC
bug affecting GCC versions 9.3-10.2 (issue #20).
Predef:
Version 1.13
Add ARCH_PPC_64 predef.
Fix ARCH_WORD_BITS* redefinition warnings/errors.
Add ARCH_E2K, Elbrus
2000, architecture from Konstantin Ivlev.
Fix not handling recent C++ version that go above 10.x version.
Version 1.12
Switch to using the endian.h header on OpenBSD. (Brad Smith)
Fix not handling recent versions of stdcxx that go above version
9.
Fix including sub-BSD OS headers directly causing redef warnings.
Add CI testing of direct inclusion of all headers.
Add CI testing on FreeBSD for clang and gcc.
Add WORD_BITS set
of predefs to detect the architecture word size. Initial implementation
inspired by submission from Mikhail Komarov.
Add CI testing for Cygwin 32 and 64.
PropertyTree:
Property Tree has a new maintainer.
Fix usage of deprecated Boost.Bind features.
Link to Wikipedia fixed.
Use BOOST_OVERRIDE to fix GCC warnings.
Add extensive CI testing.
Regex:
Regex is now header only except in C++03 mode.
Support for C++03 is now deprecated.
The library can now be used "standalone" without the rest
of Boost being present.
Stacktrace:
Better support for pre-C++11 builds on clang #102.
Bigger warning for do not use boost::stacktrace::stacktrace
in signal handlers #71.
TypeTraits:
Fix for Visual Studio managed code projects.
Variant2:

Updated Libraries
Asio:
Added ip::scope_id_type type alias.
... [More]
Added ip::port_type type alias.
Added std::hash specialisations for IP addresses.
Added std::hash specialisations for ip::basic_endpoint<>.
Refactored SFINAE usage to improve compile times.
Added friendship support to customisation points, and made most customisations
private.
Changed any_io_executor
to a "strong typedef"-style class.
Fixed experimental::as_single
to work with handler hook deprecation.
Ensured pthread condition variable attributes are cleaned up on all
platforms.
Clarified thread safety notes on sockets and descriptors.
Ensured errno is
not overwritten if socket() fails on macOS/FreeBSD.
Fixed work tracking for io_context
and thread_pool executors
when move-assigned.
Ensured internal call_stack
objects are accessed only from implementation files.
Fixed I/O object move-assignment to ensure the executor is left in
a valid state.
Fixed detection of compiler support for defaulted template argument
on functions with MSVC.
Prevented the blocking.always
property from being used with strand<>, as it did not produce the
correct semantics.
Removed deprecated file asio/impl/src.cpp.
Atomic:
Fixed compilation with MSVC for ARM. (PR#49)
Beast:
This update brings minor bug fixes and revamped CI reporting.
We'd love to know how you or your company use Beast, consider adding
an entry to the Companies
and Individuals Using Beast list.
See the full Release
Notes for a complete list of changes.
Bind:
Add support for using the standard C++11 placeholders with boost::bind.
Update boost::apply to use variadic templates
and perfect forwarding.
Container:
Added [[no-discard]] attribute in all containers to catch bugs related
to unused return values.
Replaced default standard exception classes with Boost.Container
own classes, reducing considerably the included files overhead. Example:
in MSVC 19 boost/container/vector.hpp
preprocessed file size reduces from 1,5MB to 930KB. If you still
want to use standard exception classes, you can define BOOST_CONTAINER_USE_STD_EXCEPTIONS
before using any Boost.Container class.

#102: "flat_map::insert ambiguous with initializer
list & pairs that need to convert".
GitHub
#139: "flat_map merge and iterators".
GitHub

of the C++20 standard header <bit>.
Fix BOOST_TEST_EQ,
BOOST_TEST_NE for
character types under C++20.
Revise allocator access utilities (now support VS2013, and no workarounds
use allocator_traits.)

to avoid collision with C++20 import
keyword.
Updated docs, including FAQ section.
Filesystem:
Updated compatibility with WASI platform. (PR#169)
Fixed an exception being thrown by path::remove_filename
if the path is "////". (#176)

API (e.g. Windows). The following classes were updated with wchar_t name support:
file_mapping
managed_mapped_file
managed_shared_memory
managed_windows_shared_memory
shared_memory_object
windows_shared_memory_object
file_lock
named_condition
named_condition_any
named_mutex
named_recursive_mutex
named_semaphore
named_sharable_mutex
named_upgradable_mutex
message_queue
Added BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION
macro option to disable the use of generic emulation code for process
shared synchronization primitives instead of native POSIX or Winapi
functions.

... [More]
Added ip::port_type type alias.
Added std::hash specialisations for IP addresses.
Added std::hash specialisations for ip::basic_endpoint<>.
Refactored SFINAE usage to improve compile times.
Added friendship support to customisation points, and made most customisations
private.
Changed any_io_executor
to a "strong typedef"-style class.
Fixed experimental::as_single
to work with handler hook deprecation.

objects are accessed only from implementation files.
Fixed I/O object move-assignment to ensure the executor is left in
a valid state.
Fixed detection of compiler support for defaulted template argument
on functions with MSVC.
Prevented the blocking.always
property from being used with strand<>, as it did not produce the
correct semantics.
Removed deprecated file asio/impl/src.cpp.
Atomic:
Fixed compilation with MSVC for ARM. (PR#49)
Beast:
This update brings minor bug fixes and revamped CI reporting.
We'd love to know how you or your company use Beast, consider adding
an entry to the Companies
and Individuals Using Beast list.
See the full Release
Notes for a complete list of changes.
Bind:

JSON:
Security
Report from Bishop Fox.
(#481) Refactored value_from
implementation; user customizations are now always preferred over
library-provided overloads.
(#484) Fix imprecise parsing for some floating point numbers.
(#485) Fix link errors in standalone mode, when used alongside
Boost.
(#497) Fix Boost.Build builds on GCC 4.8.
LexicalCast:
Dropped dependency on Boost.Math (thanks to Peter Dimov #37,
#39).
Fixes for the CI and coverage (thanks to Sam Darwin from "The
C++ Alliance" #38, #42).
Log:
Bug fixes:
Corrected a formal race condition in the thread-safe log record
queue implementation used in the unbounded_fifo_queue
policy of the asynchronous_sink
frontend. The race could be detected by TSAN, but it was not
a real problem on most current CPU architectures and compilers.
(#139)
When copying a logger with a channel attribute (e.g. channel_logger), the channel
attribute is now deep-copied from the original logger. This
means that modifying the channel in the new logger will no
longer affect the original logger.
Replaced the use of std::allocator<void> in template parameters
with a new tag type boost::log::use_std_allocator
to silence libc++ warnings about the former being deprecated
in C++17 and later. The tag indicates that the instantiated
template should be using a specialization of std::allocator internally to allocate
dynamic memory, so the change has no functional effect. (#141)
Boost.Log no longer defines __MSVCRT_VERSION__
macro on MinGW and MinGW-w64. Defining this macro caused incompatibility
with UCRT, which is available as an option in recent MinGW-w64.
(PR#149)
See changelog
for more details.
Math:
Breaking Change: C++03 support is
now removed, a C++11 or later conformant compiler is now required
to use this library.
Added Z-test.
Added execution policy support to univariate and bivariate statistics:
enables parallel execution (requires C++17 and <execution>).
Big update/improvement on CI testing.
Bivariate statistics now have integer support.
T-Test now has integer support.
Linear regression now has integer support.
Correct PDF of the beta distribution at the endpoints.
Correct use of Stirling's approximation in certain multiprecision
cases, fixes #396.
Eliminate -Wimplicit-int-float-conversion on clang.
Fix some constexpr issues in quaternion/octonion.
Minor performance fix to tanh_sinh integration.
Update hypergeometric functions internal scaling to allow for 64-bit
(long long) exponents with multiprecision types.
Move:
Git Issue
#35: "New nothrow move traits are incomplete".
Multiprecision:
BREAKING CHANGE: Massive refactoring
and code simplification makes C++11 an absolute requirement.
Use BOOST_TRY/CATCH in headers so code can be used in exception-free
environments.
Correct corner case in pow, fixes #277.
Correct exception type thrown to match docs in lsb/msb: fixes #257.
Allow moves and operators between related but different types (ie
types with the same allocator), fixes #278.
Nowide:
Fix discarding of characters for text file streams when seek or sync
functions are used and newlines were converted (e.g. on Windows)
Fix potential use-after-free bug when reusing (via open) a file stream that has been
closed
Fix potential invalid memory access when using a file stream that
has been moved or swapped to where the source had a put-back character
or was set to unbuffered mode
Fix compatibility with ucrt runtime by not defining __MSVCRT_VERSION__
Known issues: Read performance for text files is degraded. Binary
files and writing is unaffected.
Optional:
Fixed MSVC warning C4702.
Outcome:
Announcements:
BREAKING CHANGE: After a year and three major Boost releases
announcing this upcoming change, this is the FIRST RELEASE
of the v2.2 branch. This branch has a number of major breaking
changes to the Outcome v2.1 which shipped in Boost 1.75 and
earlier, see the documentation for details.
Enhancements:
VS2019.8 changed how to enable Coroutines, which caused Outcome
to not compile on that compiler.
If on C++ 20, we now use C++ 20 [[likely]]
instead of compiler-specific markup to indicate when TRY has
likely success or failure.
BREAKING CHANGE: Previously the value of spare_storage(const
basic_result|basic_outcome *)
noexcept was not propagated
over BOOST_OUTCOME_TRY,
which causes things like stack backtraces captured at the point
of construction of an errored result to get dropped at every
TRY point.
This has been fixed by adding an optional spare_storage
to success_type<T> and failure_type<T>, as well as to auto success(T
&&, ...)
and auto failure(T
&&, ...).
Bug fixes:
Boost.Outcome should now compile with BOOST_NO_EXCEPTIONS
defined. Thanks to Emil, maintainer of Boost.Exception, making
a change for me, Boost.Outcome should now compile with C++
exceptions globally disabled. You won't be able to use boost::exception_ptr as it can't
be included if C++ exceptions are globally disabled.
BREAKING CHANGE #244
It came as a shock to learn that BOOST_OUTCOME_TRY
had been broken since the inception of this library for certain
corner case code, which required a breaking change in how TRY
works. See the
changelog in the documentation for more detail.
Parameter:
Added a workaround for MSVC 2015 code miscompilation when an rvalue
was used as a default value of a named parameter of a function. (PR#109,
#132)
PFR:
Fixed reflection of types with missing const
in SFINAE expressions in template constructor. Now reflection of
aggregates with std::optional<std::chrono::duration??>> fields works on any
Standard Library implementation, even if LWG3050 is not fixed.
Comparison functions are now constexpr
#52
Fixed numerous typos in docs (thanks to Phil Miller #63)
PolyCollection:
Worked around GCC
bug affecting GCC versions 9.3-10.2 (issue #20).
Predef:
Version 1.13
Add ARCH_PPC_64 predef.
Fix ARCH_WORD_BITS* redefinition warnings/errors.
Add ARCH_E2K, Elbrus
2000, architecture from Konstantin Ivlev.
Fix not handling recent C++ version that go above 10.x version.
Version 1.12
Switch to using the endian.h header on OpenBSD. (Brad Smith)
Fix not handling recent versions of stdcxx that go above version
9.
Fix including sub-BSD OS headers directly causing redef warnings.
Add CI testing of direct inclusion of all headers.
Add CI testing on FreeBSD for clang and gcc.
Add WORD_BITS set
of predefs to detect the architecture word size. Initial implementation
inspired by submission from Mikhail Komarov.
Add CI testing for Cygwin 32 and 64.
PropertyTree:
Property Tree has a new maintainer.
Fix usage of deprecated Boost.Bind features.
Link to Wikipedia fixed.
Use BOOST_OVERRIDE to fix GCC warnings.
Add extensive CI testing.
Regex:
Regex is now header only except in C++03 mode.
Support for C++03 is now deprecated.
The library can now be used "standalone" without the rest
of Boost being present.
Stacktrace:
Better support for pre-C++11 builds on clang #102.
Bigger warning for do not use boost::stacktrace::stacktrace
in signal handlers #71.
TypeTraits:
Fix for Visual Studio managed code projects.
Variant2:
Improved generated code for the double buffered case.

Updated compatibility with WASI platform. (PR#169)
Fixed an exception being thrown by path::remove_filename
if the path is "////". (#176)
Fixed create_directories
disregarding errors from file status query operations issued internally.
This could result in incorrect error codes returned by create_directories. (#182)
GIL:
BREAKING: In next release, we are going to drop support for GCC 5.
We will also change the required minimum C++ version from C++11 to
C++14.
Histogram:
This release contains critical fixes, please check that your results
are not affected.
See Release
Notes for details.
Intrusive:
Reduced compile-time dependencies:
linear_slist_algorithms
use a simple node_ptr instead of std::pair on return.
list/slist use operator
</operator
== instead of std::equal_to/std::less.
Fixed GitHub
#54: set.rbegin() looks like O(log(N))
Interprocess:
Added wchar_t API support
for named resources in operating systems that offer native wide character
API (e.g. Windows). The following classes were updated with wchar_t name support:
file_mapping
managed_mapped_file
managed_shared_memory
managed_windows_shared_memory
shared_memory_object
windows_shared_memory_object
file_lock
named_condition
named_condition_any
named_mutex
named_recursive_mutex
named_semaphore
named_sharable_mutex

message_queue
Added BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION
macro option to disable the use of generic emulation code for process
shared synchronization primitives instead of native POSIX or Winapi
functions.
Fixed bugs:
GitHub
#76 ("Cygwin compilation errors").
GitHub
#83 ("Add BOOST_INTERPROCESS_FORCE_NATIVE_EMULATION
option").
GitHub

GitHub
#120 ("segment_manager customization").
GitHub
#122 ("Mark constructors/assignment/swap noexcept
where possible").
GitHub
#126 ("_ReadWriteBarrier is deprecated warning
when compiling with clang-cl.exe").
JSON:
Security
Report from Bishop Fox.
(#481) Refactored value_from
implementation; user customizations are now always preferred over
library-provided overloads.
(#484) Fix imprecise parsing for some floating point numbers.
(#485) Fix link errors in standalone mode, when used alongside
Boost.
(#497) Fix Boost.Build builds on GCC 4.8.
LexicalCast:
Dropped dependency on Boost.Math (thanks to Peter Dimov #37,
#39).
Fixes for the CI and coverage (thanks to Sam Darwin from "The
C++ Alliance" #38, #42).
Log:
Bug fixes:
Corrected a formal race condition in the thread-safe log record
queue implementation used in the unbounded_fifo_queue
policy of the asynchronous_sink
frontend. The race could be detected by TSAN, but it was not
a real problem on most current CPU architectures and compilers.
(#139)
When copying a logger with a channel attribute (e.g. channel_logger), the channel
attribute is now deep-copied from the original logger. This
means that modifying the channel in the new logger will no
longer affect the original logger.
Replaced the use of std::allocator<void> in template parameters
with a new tag type boost::log::use_std_allocator
to silence libc++ warnings about the former being deprecated
in C++17 and later. The tag indicates that the instantiated
template should be using a specialization of std::allocator internally to allocate
dynamic memory, so the change has no functional effect. (#141)
Boost.Log no longer defines __MSVCRT_VERSION__
macro on MinGW and MinGW-w64. Defining this macro caused incompatibility
with UCRT, which is available as an option in recent MinGW-w64.
(PR#149)
See changelog
for more details.
Math:
Breaking Change: C++03 support is
now removed, a C++11 or later conformant compiler is now required
to use this library.
Added Z-test.
Added execution policy support to univariate and bivariate statistics:
enables parallel execution (requires C++17 and <execution>).
Big update/improvement on CI testing.
Bivariate statistics now have integer support.
T-Test now has integer support.
Linear regression now has integer support.
Correct PDF of the beta distribution at the endpoints.
Correct use of Stirling's approximation in certain multiprecision
cases, fixes #396.
Eliminate -Wimplicit-int-float-conversion on clang.
Fix some constexpr issues in quaternion/octonion.
Minor performance fix to tanh_sinh integration.
Update hypergeometric functions internal scaling to allow for 64-bit
(long long) exponents with multiprecision types.
Move:
Git Issue
#35: "New nothrow move traits are incomplete".
Multiprecision:
BREAKING CHANGE: Massive refactoring
and code simplification makes C++11 an absolute requirement.
Use BOOST_TRY/CATCH in headers so code can be used in exception-free
environments.
Correct corner case in pow, fixes #277.
Correct exception type thrown to match docs in lsb/msb: fixes #257.
Allow moves and operators between related but different types (ie
types with the same allocator), fixes #278.
Nowide:
Fix discarding of characters for text file streams when seek or sync
functions are used and newlines were converted (e.g. on Windows)
Fix potential use-after-free bug when reusing (via open) a file stream that has been
closed
Fix potential invalid memory access when using a file stream that
has been moved or swapped to where the source had a put-back character
or was set to unbuffered mode
Fix compatibility with ucrt runtime by not defining __MSVCRT_VERSION__
Known issues: Read performance for text files is degraded. Binary
files and writing is unaffected.
Optional:
Fixed MSVC warning C4702.
Outcome:
Announcements:
BREAKING CHANGE: After a year and three major Boost releases
announcing this upcoming change, this is the FIRST RELEASE
of the v2.2 branch. This branch has a number of major breaking
changes to the Outcome v2.1 which shipped in Boost 1.75 and
earlier, see the documentation for details.
Enhancements:
VS2019.8 changed how to enable Coroutines, which caused Outcome
to not compile on that compiler.
If on C++ 20, we now use C++ 20 [[likely]]
instead of compiler-specific markup to indicate when TRY has
likely success or failure.
BREAKING CHANGE: Previously the value of spare_storage(const
basic_result|basic_outcome *)
noexcept was not propagated
over BOOST_OUTCOME_TRY,
which causes things like stack backtraces captured at the point
of construction of an errored result to get dropped at every
TRY point.
This has been fixed by adding an optional spare_storage
to success_type<T> and failure_type<T>, as well as to auto success(T
&&, ...)
and auto failure(T
&&, ...).
Bug fixes:
Boost.Outcome should now compile with BOOST_NO_EXCEPTIONS
defined. Thanks to Emil, maintainer of Boost.Exception, making
a change for me, Boost.Outcome should now compile with C++
exceptions globally disabled. You won't be able to use boost::exception_ptr as it can't
be included if C++ exceptions are globally disabled.
BREAKING CHANGE #244
It came as a shock to learn that BOOST_OUTCOME_TRY
had been broken since the inception of this library for certain
corner case code, which required a breaking change in how TRY
works. See the
changelog in the documentation for more detail.
Parameter:
Added a workaround for MSVC 2015 code miscompilation when an rvalue
was used as a default value of a named parameter of a function. (PR#109,
#132)
PFR:
Fixed reflection of types with missing const
in SFINAE expressions in template constructor. Now reflection of
aggregates with std::optional<std::chrono::duration??>> fields works on any
Standard Library implementation, even if LWG3050 is not fixed.
Comparison functions are now constexpr
#52
Fixed numerous typos in docs (thanks to Phil Miller #63)
