Since this came out, they've updated the release notes:

• For Rails 4.x please pin the gem to mysql2 '~> 0.4.0' to avoid the 0.5.x upgrade.
• For Rails 5.x the next point releases will enable both mysql2 0.4.x and 0.5.x, but until the next point release you may wish to pin the mysql2 version in your Gemfile.
