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 Kubernetes?

Kubernetes moves conformance from the cluster to the workloads running on it.

Kubernetes is between releases, and its feed is v1.37 feature deep-dives, migration guidance and ecosystem tooling. The cgroup v2 FAQ, node swap benchmarks and Memory QoS beta all push operators toward newer node defaults. The newest item is a governance move: a Workload Conformance Working Group chartered to test applications, not clusters.

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.

5.0

Kubernetes moves conformance from the cluster to the workloads running on it.

◆ Current state

Kubernetes is between releases, and its feed is v1.37 feature deep-dives, migration guidance and ecosystem tooling. The cgroup v2 FAQ, node swap benchmarks and Memory QoS beta all push operators toward newer node defaults. The newest item is a governance move: a Workload Conformance Working Group chartered to test applications, not clusters.

◆ Where it's heading

The project keeps codifying operational knowledge that operators used to hold in their heads: unused-PVC conditions, pod-level resource managers, and now a planned spec for how workloads behave during drains, upgrades and resource use. Conformance is widening from Certified Kubernetes to AI Conformance to workloads, each with objective, binary tests.

◆ Prediction

Expect the working group to publish a first requirements draft for community input, with stable tests targeted two to three release cycles out. In the meantime, the blog will likely keep shipping v1.37 graduation write-ups and migration FAQs.
