Changes (as compared to 3.12) include:
* Fixed a major memory leak issue in processlist based sniffer. Also some other small leaks were fixed.
* Using the option to ‘show only changed values’ in HISTORY/TRENDS would show an empty result for counters having non-integer values.
* On systems running Kaspersky security software ‘test connection’ could show an empty messagebox. Kapersky filtered. We have changed the text of the message so that it does not happen now.
