This CHANGELOG follows the format listed [here](https://github.com/sensu-plugins/community/blob/master/HOW_WE_CHANGELOG.md)

## [Unreleased]
### Fixed
- Align output scheme for `metrics-mysql-graphite.rb` and `metrics-mysql-processes.rb`
- Make mysql_shorthostname compliant with graphite even if 127.0.0.1 is givent as hostname
- include MR #111: Collect more innodb variables #111:
- `metrics-mysql-graphite.rb`: collect more InnoDB variables. (@boutetnico)
- include metrics gathering from `https://github.com/sensu-plugins/sensu-plugins-percona` in `metrics-mysql-graphite.rb` (there is no reason to run the gathering twice and no reasons to keep two code base)
