We are happy to announce the release of MISP v2.5.37, headlined by the brand-new Event Templating system — a complete redesign that replaces the legacy templating engine. This release also introduces a dedicated suricata attribute type, continues the Overmind UI migration, switches the STIX 2 stack to the upstream library bundled with misp-stix, ships several security fixes, and brings new performance tooling for large instances.
