Resend
Resend is wiring itself into every agent runtime it can reach, and now adding the controls to stop a send.
A side-by-side editorial comparison of MISP and RabbitMQ — release velocity, themes, recent moves, and the top alternatives to consider.
MISP extends instance-to-instance sync to collections while a security-hardening program runs underneath
MISP is shipping on a roughly two-week cadence, and three tracks run through every release. The first is federation: 2.5.43 added collection synchronisation between instances in both pull and push directions, with per-server toggles and feature negotiation. The second is a sustained security program — 2.5.40, 2.5.41 and 2.5.42 are all substantially security releases, with 2.5.42 alone closing two RCE vectors and a mass-assignment sweep across a 74-controller review. The third is the Overmind UI migration to Bootstrap 5, which lands a batch of converted views in nearly every release.
Two parallel trains, and the 'maintenance' label is now hiding real feature work
RabbitMQ is maintaining 4.2.x and 4.3.x side by side, cutting matching patches into both on the same day, and both trains raised their floor to Erlang/OTP 27. Most of the window is correctness work in the Raft-backed subsystems — quorum queues losing metrics after a restart, leaders committing log entries too optimistically, classic queue index paths accumulating slashes, topic bindings with empty routing keys matching everything. The newest 4.3.5, however, is labelled a maintenance release while carrying encrypted management-UI login tokens, a new authentication logging category, ETag support on the definitions endpoint, and a self-deleting Shovel TTL.

The security work reads as a deliberate audit rather than incident response — the fixes are systematic (mass-assignment and broken-access-control across the controller layer, OIDC hardening, ACL enforcement on cluster search) and credited to named external researchers across four consecutive releases. Alongside it, the interop surface keeps widening: TAXII 2 conformance and scheduled push, STIX moved onto the upstream misp-stix library, and now collection sync. The Overmind migration is the slow constant, converting the UI tab by tab rather than in one cutover.
The Overmind migration and the Pivotick pivot explorer are both mid-rollout, so the next releases should continue converting views and fill out Pivotick rather than open a new track. Given the pattern of the last four releases, expect further externally-reported security fixes to ship alongside them.
RabbitMQ is maintaining 4.2.x and 4.3.x side by side, cutting matching patches into both on the same day, and both trains raised their floor to Erlang/OTP 27. Most of the window is correctness work in the Raft-backed subsystems — quorum queues losing metrics after a restart, leaders committing log entries too optimistically, classic queue index paths accumulating slashes, topic bindings with empty routing keys matching everything. The newest 4.3.5, however, is labelled a maintenance release while carrying encrypted management-UI login tokens, a new authentication logging category, ETag support on the definitions endpoint, and a self-deleting Shovel TTL.
The bug pattern remains the tell: nearly every fix is in quorum queues, Khepri or Raft, which is where RabbitMQ moved its metadata and durability story after 4.3.0 removed Mnesia and partition-handling strategies outright. Layered on top is a steady tightening of the operational perimeter — protocol parsers rejecting malformed input strictly across AMQP 1.0, MQTT 5.0 and STOMP, pre-authentication frame limits on stream connections, HTTP API endpoints validating node membership, and headers that stop disclosing supported methods. Feature work is arriving inside patch releases rather than waiting for a minor.
Expect the 4.2.x train to slow toward end-of-life while 4.3.x patches keep absorbing both Khepri edge cases and security-surface work. The encrypted login token, currently opt-in behind a shared cluster secret, is the kind of setting that gets promoted to a default once rolling-upgrade friction is behind it.
