+### Added
+
+- Support "plain" `Redis` as a cache store backend ([#280](https://github.com/kickstarter/rack-attack/pull/280)). Thanks @bfad and @ryandv.
+- When overwriting `Rack::Attack.throttled_response` you can now access the exact epoch integer that was used for caching
+so your custom code is less prone to race conditions ([#282](https://github.com/kickstarter/rack-attack/pull/282)). Thanks @doliveirakn.
+
+### Dependency changes
+
+- Explictly declare ancient `rack 0.x` series as incompatible in gemspec
