+===== Mon Jan 3 2020 - v2.6.0 =====
+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.

+===== Tue Sep 3 2019 - v2.5.0 =====
+We have just released Mentat version **2.5.0**. This release brings in major improvements in reporting component. Online reports are now more interactive and integrated into other parts of the system, there are context actions available for each node. On top of that there is a simple feedback button available for each address in each report section, so that users may provide their feedback more comfortably. System Mentat is now capable of enriching displayed information with data from third party services like DNS, PassiveDNS, NERD, WHOIS and GeoIP. There is a new module available currently for system administrators that attempts to display all available information for single IP address. Group membership management was simplified to enable group managers to more easily add or remove members and even activate new user accounts. Additionally we have also managed to squash quite a few bugs.
+It is also worth noting, that this version also attempts to speed up the database searching by using aggregated IP ranges to narrow down the number of searched rows even more.
