Changes (as compared to 4.0) include:
* Implemented code that makes OpenSSL (what is used by our SSH-library) explicitly thread-safe and thus fixing an issue where specific cryptographic function calls under very heavy load could cause a crash.
* Fixed a SQLite corruption issue that on Windows could cause failure to stop the MONyog service. The issue did not mean that MONyog as such stopped working as long as it was running.
* If both value for 'user' and 'host' were filtered in processlist-based sniffer the interface would display NULL for both.
