Sixth round of improvements in 2.x series This release brings in further improvements to our reporting component. Reports are now templated according to the classification of each reported event to provide recipients with most important information relevant to that event class. This new feature is fully configurable for administrators of Mentat system, soon user manual will be provided. Additionally lot of work went into database optimizations. First the PostgreSQL was upgraded to latest version 12. Next we have increased the amount of possible paralel queries by separating stored IDEA BSON to different table. We have implemented basic DoS prevention mechanism by limiting number of queries each user may execute at any given time. We have also increased the speed in which IDEA events are stored into database by using bulk inserts. The MaxMind IP geolocation service recently changed its policies for accessing their free databases, so we have addressed this issue as well as the change with access policies to CESNET PassiveDNS service.
