 Upgrading SlackRubyBot
 ======================
 
+### Upgrading to >= 0.9.0
+
+#### Add giphy to your Gemfile for GIF support
+
+The dependency on the `giphy` gem was dropped and GIFs don't appear by default. If you want GIF support, add `gem 'giphy'` to your **Gemfile**.
+
+You should not need to make any changes if you had already disabled GIFs for your bot.
+
+See [#89](https://github.com/slack-ruby/slack-ruby-bot/pull/89) for more information.
+
 ### Upgrading to >= 0.8.0
 
 #### Require a concurrency library
 
 The `faye-websocket` library is no longer required by default. Add either `faye-websocket` or `celluiloid-io` to your `Gemfile` depending on which concurrency implementation you'd like to use. We recommend `celluloid-io` moving forward.

 The regular expression parser for commands will now include a `nil` value for `expression` when an expression is not present. You can therefore no longer rely on checking `match.names.include?('expression')`, instead check `match['expression']`.
 
 #### Remove any bot.auth! calls
 
-SlackRubyBot 0.6.x versions invoked a method called `auth!`, which caused a pre-flight authentication via Slack Web API `auth_test` method and collected a number of properties, such as client and team ID or name. This method has been removed in favor of using data available in the `Slack::RealTime::Client` local store introduced in [slack-ruby-client#54](https://github.com/dblock/slack-ruby-client/issues/54). Remove any explicit calls to this method.

 The command interface now takes a `client` parameter, which is the RealTime Messaging API instance. Add the new parameter to all `call` calls in classes that inherit from `SlackRubyBot::Commands::Base`.
