Heroku Deploys With Rollbacks and Changelog

One of the features I miss from Capistrano is the ability to easily do rollbacks when deploying to Heroku. What you can easily do though is git tag your releases and then do a rollback by pushing the previous release tag. I've created a RubyGem called heroku_release that does this. The gem has a few additional features such as the ability to generate a CHANGELOG file from the release tags and their comments. I also use it to generate a version file so that I can check on the live server what version of the code it is running.

It's interesting to note that Heroku is apparently working on supporting release management and logging - two problems I have ended up rolling my own solutions for recently. I look forward to seeing what they have come up with.
