Microsoft's CodePlex foundation has announced the donation of $25,000 to support the development of the Mercurial source code management system. "While Team Foundation Server is still the most used version control system on CodePlex, our users are clearly benefiting from having access to Mercurial for their open source projects. The CodePlex team is happy to be able to offer our community of more than 17,000 projects a choice. With Mercurial as an important feature of CodePlex, we are excited to be making this donation to help support the Mercurial project."
