Beanstalk is a code hosting and development service with support for Git and Subversion. It integrates with a variety of services and offers easy deployment to servers.
We had support for Bitbucket with Mercurial, but due to some missing API, we couldn't integrate with Git. That's been solved in 1.7.13, if you also use RBTools 0.5.2.
There's also a handful of other fixes and improvements in this release.
While you're upgrading, we recommend making some additional changes to your Apache configuration. See the updates on our guide to securing file attachments.
See the release notes for more information on what's in 1.7.13.
