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 Windmill — 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.
Windmill gave away the warehouse connectors and now runs dbt natively — the trial is the strategy.
Two lines are moving at once. The platform line made dbt projects a first-class runtime, unified the deployment target on workspace lineage, opened Compare & Deploy to arbitrary target workspaces, and moved BigQuery and Snowflake out from behind the Enterprise license. The AI line took sessions to beta on by default and has been adding controls around them since — file attachments, visible web-search sources, artifact version history, and now a read-only plan mode that refuses anything that writes or deploys until you approve a plan.

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.

Windmill is positioning as the place a data team's existing work already runs rather than a system to be ported to: an unmodified dbt project drops in, its models become addressable assets with ref() lineage, and the warehouse languages needed to reach them are no longer paywalled. In parallel, the AI session work is maturing from capability to governance — the recent additions are all about reviewability and constraint, not raw autonomy. The deployment changes point the same way, collapsing configurable targets into a single derived answer.
Expect the plan-and-approve posture to spread beyond session chats into the durable AI surfaces, and more warehouse-adjacent runtimes to follow dbt into the first-class treatment; Oracle and MS SQL remain the obvious Enterprise holdouts to watch.
