Harbor
Harbor's patch train is now mostly about undoing regressions from its own security hardening.
A side-by-side editorial comparison of MISP and Tyk — release velocity, themes, recent moves, and the top alternatives to consider.
MISP 2.5.50 deletes legacy discussions, templates and allowedlists as security fixes keep coming.
MISP is deep in a security-remediation cycle: 2.5.46, 2.5.47, 2.5.48 and now 2.5.50 each ship externally reported fixes, and 2.4.221 backported 57 of them to the EOL branch. 2.5.47 added PostgreSQL support and a first AI-assisted analysis integration. 2.5.50 moves Redis host settings to CLI-only and closes event-index and object-search information leaks. It also starts deleting legacy features outright.
Tyk is in maintenance mode on four release lines at once, with 5.16 barely stirring.
Tyk's recent output is almost entirely release candidates across the 5.8, 5.13 and 5.15 branches, driven by a single dependency-and-CVE ticket (TT-18285) that bumped kin-openapi, golang.org/x/crypto, thrift and the OTLP trace exporters. The only forward-looking change is a 5.16 alpha in which the Gateway reports node metadata to the Dashboard on register and heartbeat.

It also starts deleting legacy features outright.
The project is shifting from adding hardening patches to shrinking its attack surface. In 2.5.50, event discussions become analyst notes, legacy templates become event templates, and signature allowedlists become warninglists, with migrations and logged failures. Combined with the Overmind UI migration and the database abstraction, this looks like a deliberate cleanup of the 2.5 codebase.
Expect further legacy features to be migrated and removed in the next releases, alongside more advisories from the ongoing review. Admins with workflows on the removed discussion trigger will need to adapt.

The only forward-looking change is a 5.16 alpha in which the Gateway reports node metadata to the Dashboard on register and heartbeat.
The pattern is a vendor servicing a long tail of supported enterprise branches, backporting the same security fixes everywhere rather than shipping features. The 5.16 alpha points toward better fleet visibility between Gateway and Dashboard, a control-plane concern rather than a new API-management capability.
Expect GA patch releases for 5.13.4 and 5.15.1 carrying the TT-18285 dependency fixes, followed by further 5.16 alphas. The entries don't show what headline feature 5.16 will carry.
