We released version of 0.9 of the gem today with the following improvements:

• It's now possible to override the revision in Capistrano deploy notifications by using set :appsignal_revision, 'revision'.
• We've refactored the way we use Thread.local to make it easier to use AppSignal in tasks and processes outside of a web app.
• Net::HTTP requests in your code are now automatically instrumented.
• And last but not least, deploy notifications in Capistrano 3+ now work out of the box!

Enjoy!
