We now have a sizable chunk of features that we can release. We should create a release branch from dev. This release branch should be named after the version of the release, prefixed by release/, such as release/0.1.0. The code to be released should then be deployed to a staging server, where automated UI testing, manual testing, and acceptance testing should be conducted (more on these later). Any bug fixes should be committed on the release branch and merged back into the dev branch. When the release branch is ready, it can then be merged into master.
No new features should be added to the release branch except bug fixes and hotfixes. Any new features, non-critical bug fixes, or bug fixes that are unrelated to the release should be committed to a bug-fix branch.
So, the first question is how do we name/version our releases? For this project...
