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 RabbitMQ and ZoneMinder — release velocity, themes, recent moves, and the top alternatives to consider.
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.
1.38.4 is a security release in all but name, closing ACL gaps across the API.
The 1.38 line is in maintenance, and 1.38.4 is almost entirely authorization work: per-monitor access control enforced on event, frame, zone, tag and media endpoints, two auth bypasses fixed in token validation, and SQL injection and overflow hardening. The 1.36 branch still receives backports, with 1.36.38 carrying its own SQL injection fix. The last feature release was 1.38.0 in February, which brought role-based access control, WebRTC and Go2RTC streaming, and the split of monitor function into separate capturing, analysing, and recording settings.

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.

The last feature release was 1.38.0 in February, which brought role-based access control, WebRTC and Go2RTC streaming, and the split of monitor function into separate capturing, analysing, and recording settings.
Every release since 1.38.0 has been consolidation of what that release opened up. RBAC shipped as a headline feature in February, and the four maintenance drops since have been finding the endpoints it did not cover — the familiar pattern when a permission model is retrofitted onto an API that predates it. Cadence is slow and irregular, months apart, with a 1.39 spec bump already visible in the repo but nothing from that series shipped.
Expect more per-endpoint ACL fixes on the 1.38 line before anything from 1.39 reaches release.
