Eight round of improvements in 2.X series In this release together with upgrade to PostgreSQL 13 aggregated column indices finally come to fruition and we are able to significantly push down search times of IP address and range based queries from tens of seconds to (usually) subsecond speed. Together with overlapping range aggregation for storage of source/target heavy events it seems we have finally finished our performance goal, which started by switching from MongoDB to PostgreSQL. Toast time. (Even though Mentat 2.8 will run on older PostgreSQL instances, to take advantage on those improvements you have to upgrade to PostgreSQL 13.) Timeline aggregation framework now prominently replaces Hosts view in the main menu and is now better integrated with Event search. Also, usual set of bugfixes, UI, API, documentation and framework cleanup went in. Mentat specific namespace within events was originally _CESNET. As a means to shed company dependencies, the key is now renamed to _Mentat. It is advisable to review the Inspector configuration for rules related to the keys in this namespace and to review possible related homegrown code. Multiple instances of Inspector are now folded into one with a default ruleset merged in pursue for a simpler default configuration. If you use the default configuration, you can just use new default Inspector and Controller configuration (which installation from Debian packages does for you). If you've made local changes, you might review new distribution configuration files and also decide to merge.
