Changes (as compared to Monyog MySQL Monitor 5.6) include:

Miscellaneous:
* This release includes internal optimizations and code cleanups that did not find its way to the 5.6 release. There are no changes in User Interface or in functionalities due to this.
* MySQL 3.23 and 4.0 servers are no longer supported and an attempt to register such will be denied. If such servers are already registered, data collection from those will be stopped (and cannot be resumed) first time Monyog starts after the upgrade to this version.
