Application Templates: MS Exchange 2013 application templates have been added (“Other Applications and Services” category).
Monitoring Service: HTTP(S) monitors do not report SSL certificates errors for valid certificates, when instructed to ignore certificate errors.
New variable templates have been added, expanded to currently used user credentials (for Unix-like, Windows and SNMP credentials). It allows to pass the credentials to scripts or program used by monitor, for both monitor definition and alerting.
Several bugs have been fixed. You can find more information about the release in Release Notes.
