Apache Airflow
Airflow 3.4 moves to a second release candidate three days after the first.
A side-by-side editorial comparison of Duplicati and RabbitMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Duplicati 2.4.1 stable brings delta backups for Microsoft 365 and scheduled restore tests.
Duplicati 2.4.1.0 stable moved the canary work into the main line: Microsoft 365 and Google Workspace backups list only what changed since the previous run, and a restore test operation verifies a sample in a temporary folder, optionally after each backup. Point-in-time destination reads, version labels and object locks on Duplicati Storage landed with it. The 2.4.1.100 canary now goes after silent failures: stalled reads that reported success, unreadable source folders that produced empty versions, and dry runs that changed the database.
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 2.4 line is about proving backups can be recovered, and the newest canary extends that to refusing to report success when data is incomplete. Delta tracking for SaaS sources shows Duplicati treating cloud workloads as primary sources, and console-set restore tests give its hosted console a role in managing fleets of machines.
Expect the 2.4.1.100 timeout and integrity fixes to reach a stable patch, with the Hyper-V and MSSQL source rework following from canary.
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.

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.
