This release primarily adds new features: configuration options,
scripting language functionality, and a new "supervisor" deployment
mode (alternative to ZeekControl). Performance is improved, especially
the handling of SYN-scans and also JSON logging. The main I/O loop of
Zeek is rewritten with better idle behavior and reduced CPU load. It
also includes many smaller bug fixes and improvements.

Further release notes can be read in the NEWS file or here:

receiving bug fixes until at least October 2020.
