 Upgrading SlackRubyBot
 ======================
 
+### Upgrading to >= 0.15.0
+
+#### Set up VCR explicitly
+
+Requiring `slack-ruby-bot/rspec` will no longer set up [VCR](https://rubygems.org/gems/vcr) anymore. If your spec suite implicitly relies on this you would need to set up VCR explicitly in your spec suite. Just follow standard VCR documentation.
+
+See [#258](https://github.com/slack-ruby/slack-ruby-bot/pull/258) for more information.
+
 ### Upgrading to >= 0.14.0
 
 #### Bot Messages Disabled
 
 By default bots will no longer respond to other bots. This caused confusing "I don't understand this command." errors when DMing the bot and rendering URLs that were being sent back as DMs. If you wish to restore the old behavior, set `allow_bot_messages` to `true`.
