What is Apereo CAS?

CAS 8.0 is six release candidates deep with notes that describe nothing

Apereo CAS is working through a long v8.0.0 release-candidate series, reaching RC6 by late June 2026. The candidates are published with a fixed template — links to release notes, documentation, commit log and policies, plus contributor thanks — and no description of what each one changed, so the substance of the 8.0 cycle is not readable from the releases themselves. The one entry with real content is v7.3.7.1, a patch pointing at a published OIDC vulnerability advisory.

What is Strimzi?

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

CAS 8.0 is six release candidates deep with notes that describe nothing

◆ Current state

Apereo CAS is working through a long v8.0.0 release-candidate series, reaching RC6 by late June 2026. The candidates are published with a fixed template — links to release notes, documentation, commit log and policies, plus contributor thanks — and no description of what each one changed, so the substance of the 8.0 cycle is not readable from the releases themselves. The one entry with real content is v7.3.7.1, a patch pointing at a published OIDC vulnerability advisory.

◆ Where it's heading

The observable pattern is a maintained v7 line receiving security patches while v8 advances through candidates at roughly monthly intervals with a small, stable set of contributors. Beyond that, the release notes are too thin to establish what 8.0 changes for operators, which matters for an identity product where upgrade planning depends on knowing exactly what moved.

◆ Prediction

Expect the RC series to continue at a monthly cadence toward an 8.0 release, and the v7 line to keep receiving security patches; what 8.0 actually delivers cannot be predicted from these entries.

Strimzi's 1.2.0 candidate closes with a logging fix and nothing else

◆ Current state

The 1.2.0 release cycle has reached its second candidate, and it is a small one: a single fix for incorrect CA logging on top of rc1. Everything substantive in this release landed in rc1 — Kafka 4.3.1 support, per-pod volume templates, and server-side apply now permanently enabled. This feed publishes only release candidates and never the finals, so an rc is the record of what shipped.

◆ Where it's heading

Post-1.0 Strimzi is spending its cycles on how the operator manages Kubernetes resources rather than on new Kafka surface. ServerSideApplyPhase1 has gone alpha to GA and is now always on, and 1.2.0 changes install-time defaults toward Restricted Pod Security Standard security contexts and volume-mounted Service Account tokens. A second candidate carrying one logging fix says the cycle is converging rather than still absorbing change — the CRD v1-only requirement from 1.0.0 remains the loudest thing in every release body.

◆ Prediction

Expect 1.2.0 final shortly with no further candidates, and the next cycle to advance one of the open feature gates — UseBackgroundPodDeletion is the likeliest to move from alpha to beta.
