Flipper 0.25.0

Hello from Nevada and Great Basin National Park!

I'm vacationing (12 national parks) so this release email is a little tardy. But better late than never, right?

Breaking Changes

  • Removed previously deprecated options and settings. Those upgrading from <0.21 should upgrade to ~>0.24 first and fix any deprecation warnings when initializing Flipper.


  • Added a prompt in Flipper UI for the 'Delete' button to prevent accidental delete of features
  • Added failsafe adapter for if you want flipper to return false instead of raising an error if things go wrong talking to an adapter.
  • ActiveRecord: base class for internal models to ease connecting to an alternate database.
  • Remove use of Rack::BodyProxy in the memoizer middleware.

That's all for today. Enjoy!
