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 Argo Rollouts and RabbitMQ — release velocity, themes, recent moves, and the top alternatives to consider.
An RC-only feed where 1.9's headline change was reverted before it shipped.
Every entry in this window is a release candidate; no GA tag appears at all. The 1.9 line spent three RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn. That change would have narrowed .status.selector to report only the stable ReplicaSet for traffic-routed canaries so HPA stopped counting canary pods in its desired-replica math. The 1.10.0-rc1 notes are dominated by build and dependency work.
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 visible direction is operational rather than behavioural: notifications broadened to Teams workflows and NATS.io, a build system parameterized for company forks, CI skipped for docs-only changes, a move to pnpm. The selector revert says the project would rather live with awkward HPA math than break autoscaling for existing users, so progressive-delivery mechanics stay where they are.
1.10.0 looks likely to land close to rc1 — dependency, CVE and notification work with no controller-semantics change — and the HPA selector question stays open unless it returns behind an opt-in flag.

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.
