     - `:telegram_bot` rspec tag is replaced with `telegram_bot: :rails`.
 - __Breaking change__. Use bang-methods as actions for commands.
   This prevents calling context contextual actions and payload specific actions with commands.
+  Translation helper strips `!` from action name for lazy translations.
 - __Breaking change__. Drop `.context_handler`, `.context_to_action!` methods.
   Use pass action name directly to `#save_context`.
   It's the same as `.context_to_action!` is enabled by default.
