What is Authelia?

Authelia's 4.39.x series is a continuous patch stream: five releases in nine days, no new features

Authelia is in a sustained maintenance phase on the 4.39.x branch. The project has shipped at least five releases since September 8 — all bug-fix patches targeting OIDC conformance, web UI edge cases, SMTP IPv6, Envoy authz path handling, and storage correctness. The release cadence is high but the content is narrow: there is no visible feature investment in the recent window.

What is Thanos?

Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.

Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.

Authelia's 4.39.x series is a continuous patch stream: five releases in nine days, no new features

◆ Current state

Authelia is in a sustained maintenance phase on the 4.39.x branch. The project has shipped at least five releases since September 8 — all bug-fix patches targeting OIDC conformance, web UI edge cases, SMTP IPv6, Envoy authz path handling, and storage correctness. The release cadence is high but the content is narrow: there is no visible feature investment in the recent window.

◆ Where it's heading

The pattern across these releases is OIDC stabilization — multiple entries address consent handling, resource indicators, and JWT grant correctness. Authelia appears to be closing out conformance gaps accumulated during earlier 4.39.x development rather than adding surface area. The active committer footprint is small (primarily @james-d-elliott), which keeps the pace sustainable but limits breadth.

◆ Prediction

Given the absence of feature releases since well before May 2026, a 4.40.x or 5.0 branch with new capabilities is likely being developed in parallel. The current stream is support-mode maintenance.

Thanos is rebuilding Receive around multi-tenancy, and shipping it through a stuttering RC train.

◆ Current state

Thanos is working through the 0.42.0 release candidates, where the headline work is on Receive: tenant lifecycle handling, per-endpoint configuration, and fanout information surfaced in Thanos Query. The line also adopted Go's *os.Root API, which rc.2 exists mainly to clean up after. The release pipeline itself has been unreliable — rc.0 was skipped outright because base image SHA updates broke it, so rc.1 and rc.2 carry identical feature notes.

◆ Where it's heading

The centre of gravity is multi-tenant operation. Per-endpoint configuration and tenant lifecycle handling are what an operator needs to run one Thanos install for many teams rather than one per team, and the Query fanout view is the observability that makes such a topology debuggable. The parallel fixes to multi-tier query setups — preserving external label matchers across Query A → Query B → Sidecar chains — point at the same reality: deployments are getting deeper, not just wider.

◆ Prediction

A 0.42.0 stable should follow once the *os.Root regressions settle. The RC notes are cumulative and the feed is quiet since June, so treat cadence here as release-train artefact rather than a slowdown in the project.
