What is Coolify?

After four quiet months, Coolify's v4.4 candidate arrives carrying single sign-on.

Coolify has published the first release candidate for v4.4, its first entry since late April — a four-month gap in a feed that had been running on near-weekly betas. The release is dominated by authentication: first-class OpenID Connect with discovery, JWKS signing-key resolution, token validation, PKCE and identity linking, plus registration-policy controls and an option to auto-join OIDC users to the root team. Team-scoped integration tokens land alongside it, with their own create, edit and permission handling. It is explicitly not for production use.

What is NATS?

NATS 2.15 introduces a desired-state reconciliation engine for JetStream, making cluster operations safe to run mid-flight.

NATS is in the RC phase for v2.15, which centers on a new desired-state metalayer for JetStream — a reconciliation engine that makes stream and consumer placement changes safe to execute during ongoing operations. Cancelling in-flight scale/move operations, changing replication factors mid-move, and peer-removing are all significantly safer. The parallel v2.14.7 release backports metalayer compatibility and fixes a set of JetStream data races and consumer state bugs identified during 2.15 testing.

After four quiet months, Coolify's v4.4 candidate arrives carrying single sign-on.

◆ Current state

Coolify has published the first release candidate for v4.4, its first entry since late April — a four-month gap in a feed that had been running on near-weekly betas. The release is dominated by authentication: first-class OpenID Connect with discovery, JWKS signing-key resolution, token validation, PKCE and identity linking, plus registration-policy controls and an option to auto-join OIDC users to the root team. Team-scoped integration tokens land alongside it, with their own create, edit and permission handling. It is explicitly not for production use.

◆ Where it's heading

The earlier beta run was security hardening — team-scoped queries, encrypted webhook secrets, mass-assignment protection, a guard against pruning persistent containers. v4.4 continues that line but changes its character: where the betas were closing holes in a single-team deployment, OIDC and team-scoped integration tokens are the features an organisation requires before it will let a self-hosted PaaS hold its infrastructure. Identity delegated to a corporate provider, and API access scoped per team, are the two things that were missing. The long publishing gap and the jump from a beta.474 numbering to a 4.4 candidate suggest the work was done off the release feed rather than paused.

◆ Prediction

The stable v4.4 is the next thing to expect and the release where this work should be judged, since the candidate ships explicitly for testing. Given the OIDC groundwork now includes registration policy and team auto-join, group or role mapping from the identity provider is the natural follow-on once SSO itself settles.

NATS 2.15 introduces a desired-state reconciliation engine for JetStream, making cluster operations safe to run mid-flight.

◆ Current state

NATS is in the RC phase for v2.15, which centers on a new desired-state metalayer for JetStream — a reconciliation engine that makes stream and consumer placement changes safe to execute during ongoing operations. Cancelling in-flight scale/move operations, changing replication factors mid-move, and peer-removing are all significantly safer. The parallel v2.14.7 release backports metalayer compatibility and fixes a set of JetStream data races and consumer state bugs identified during 2.15 testing.

◆ Where it's heading

The desired-state metalayer is an architectural addition that addresses a real operational risk: JetStream's previous behavior required careful sequencing of cluster topology changes to avoid data loss or inconsistent state. The pattern across recent releases — isolated stream read locks, constant-time removal from service maps, reduced client buffer flushing — shows a systematic performance and correctness pass across JetStream at high scale. NATS is moving toward the safety properties needed for production-critical stateful messaging.

◆ Prediction

v2.15.0 GA will likely ship within weeks of RC.2. The next cycle will probably extend desired-state semantics to more JetStream operations and potentially introduce observability tooling around reconciliation state, giving operators visibility into in-progress cluster changes.
