Such a lengthy source control history in conjunction with recent activity may indicate that this code base and community are important enough to attract long-term commitment, and may also indicate a mature and relatively bug-free code base.
A high number of comments might indicate that the code is well-documented and organized, and could be a sign of a helpful and disciplined development team.
For this measurement, Open Hub considers only recent changes to the code. Over the entire history of the project, 538 developers have contributed.
Open Hub makes this determination by comparing the total number of commits made by all developers during the most recent twelve months with the same figure for the prior twelve months. The number of developers and total lines of code are not considered.
