4.0.1

• Fixed: Handlers with no configuration will no longer cause an attribute to appear on Lita.config.handlers.

4.0.0

See the Lita 4 release announcement on Lita.io.

3.3.1

• Fixed: When using the shell adapter, input will be properly encoded as UTF-8. (#57)

3.3.0

• Added: Readline support for the shell adapter.
• Fixed: The abstract methods in Lita::Adapter will no longer crash due to number of arguments supplied.
• Changed: Generated plugins now use the final release version of RSpec 3.0.
• Changed: The "info" command and /lita/info HTTP endpoint now return information about Redis.
• Changed: The :validate_route hook now receives the handler class in the hook payload under the key :handler.
• Changed: The :validate_route hook is now invoked as the last check during incoming message dispatch, so hooks can assume the incoming message would otherwise have been dispatched to the current route.
• Added: Lita::Handler.dispatch_to_route, which allows a handler route to be invoked directly, bypassing the usual conditional checks.

3.2.0

• Added: A new plugin type, extensions, allow developers to hook into core Lita behavior to extend the capabilities of the core, and to provide new features to adapters and handlers.
• Added: A generator command to create new extension plugins: lita extension NAME.
• Added: A new hook system extensions can use to tap into Lita's core. Register callback objects with Lita.register_hook(:hook_name, MyCallbackObject). MyCallbackObject is any object that responds to :call and accepts a hash of arbitrary payload data.
• Added: New hook: :before_run. Called when Lita.run is called. Useful for extensions that need to do something just as the robot starts. The payload contains the path to the Lita config file, if any.
• Added: New hook: :validate_route. Called during incoming message dispatch. Can be used for custom logic to determine whether or not a message should match a route. The payload contains the route object, the incoming message object, and the currently running robot.
• Added: New hook: :trigger_route. Called when a message has matched a route, just before the handler's callback method is invoked. The payload contains the route object and the response object.
• Changed: Lita::Handler.route now accepts arbitrary keyword arguments. Any extra arguments will be accessible by hooks via Lita::Handler::Route#extensions.
• Added: Lita::Response#extensions, a hash of arbitrary data Lita extensions can use to enhance handler functionality.
• Added: Lita::Handler#config, a shortcut handlers can use to access their own Config object.
• Added: Lita::Handler#log, a shortcut handlers can use to access the global Lita logger object.
• Changed: Lita.clear_config's primary method name is Lita.reset_config, though clear_config still works as well.
• Added: New methods for resetting (clearing) various global registries: Lita.reset_adapters, Lita.reset_handlers, and Lita.reset_hooks. Lita.reset will reset everything: adapters, config, handlers, and hooks.

3.1.0

• Added: Lita::Message#reply_with_mention (also accessible via Lita::Response#reply_with_mention) for replying to messages in group chat and prepending the mention name of the original message sender.
• Added: Lita::Robot#send_messages_with_mention for mentioning a user in a message that is not a direct response to an incoming message.
• Added: Lita::User#mention_name as an official accessor method for the mention name of a user.
• Added: Lita::Adapter#mention_format, which allows adapters to define the syntax for triggering a user mention for the chat service.

3.0.4

• Fixed: User.create will now persist the provided metadata when the provided ID is for an existing user.
• Changed: User metadata keys are now normalized to strings.
• Fixed: Timers created with Handler#after and Handler#every will no longer block the handler thread.
• Changed: The memory profile of recurring timers has been improved.

3.0.3

Fixed: The plugin generator will now create plugins structured so that localization files will be properly loaded before the plugin class is defined.

3.0.2

• Changed: Generated plugins will depend on RSpec 3.
• Changed: Generated lita_config.rb files show an example for configuring the locale.

3.0.1

Fixed: Lita will abort with a nice error message if Lita::RSpec is required without RSpec 3.
