What is Quay?

The public release feed is pure CVE backporting across two frozen branches.

Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.

What is Casdoor?

Casdoor is turning single-tenant SSO into per-organization governance, one small release at a time

Casdoor ships multiple tagged releases a week, each carrying one or two commits, with version-only titles that hide the work. The current cluster is governance plumbing: configurable record and token retention per organization, auto-revoking permissions after an expiry window, and a batch UpdatePermissions API that cuts how often the Casbin enforcer rebuilds. Alongside it runs steady OAuth/OIDC conformance work — RFC 8707 resource indicators preserved through fast auto-signin, a backchannel logout URL on the application edit page.

Quay vs Casdoor: editorial side-by-side

Q
Quay
INFRA · APIS
5.0

The public release feed is pure CVE backporting across two frozen branches.

◆ Current state

Quay's tracked releases are entirely maintenance work on the 3.10 and 3.12 branches, and nothing else appears in the feed. Every entry is a list of dependency CVE fixes and Go version bumps, cherry-picked between branches by automation — the same PyJWT, urllib3, axios, shell-quote and kafka-python advisories land on both lines within days. The one piece of actual product code in this window is an SSRF fix in the proxy cache upstream registry configuration.

◆ Where it's heading

This is what a supported enterprise registry looks like from the outside: two older branches on life support for customers who have not moved, with feature development happening somewhere the feed does not see. The pattern is machine-driven — cherry-pick robots, changelog bump bots, Renovate-style dependency updates — with human authorship visible mainly on the security fixes. Nothing here indicates what the current development branch is doing.

◆ Prediction

Expect the 3.10 and 3.12 branches to keep receiving paired dependency CVE backports on the same cadence until their support windows close. Any read on Quay's product direction needs a source other than this feed.

Casdoor is turning single-tenant SSO into per-organization governance, one small release at a time

◆ Current state

Casdoor ships multiple tagged releases a week, each carrying one or two commits, with version-only titles that hide the work. The current cluster is governance plumbing: configurable record and token retention per organization, auto-revoking permissions after an expiry window, and a batch UpdatePermissions API that cuts how often the Casbin enforcer rebuilds. Alongside it runs steady OAuth/OIDC conformance work — RFC 8707 resource indicators preserved through fast auto-signin, a backchannel logout URL on the application edit page.

◆ Where it's heading

The center of gravity has moved from 'can users sign in' to 'can an operator govern what happens after they do.' Retention windows, permission expiry, and rename-safe Casbin group rules are all multi-tenant administration concerns, and each is being made configurable per organization rather than per deployment. The Casbin enforcer rebuild cost surfacing as its own fix suggests these installs are getting large enough for permission-model performance to matter.

◆ Prediction

Expect more per-organization lifecycle policy knobs and continued work on Casbin enforcer performance, since both themes have produced several releases in the last week alone.
