What is oVirt?

A virtualization manager coasting on backports, with releases years apart

oVirt Engine's release feed is sparse and slowing: 4.5.5 in late 2023, 4.5.6 and a pair of 4.5.3.x backports in early 2024, then nothing until 4.5.7 in December 2025. Almost every entry is a list of targeted fixes and backports rather than features — OVF import edge cases, template handling, NVRAM save/restore logic, CA generation as a non-root user, Keycloak group handling. One CVE, CVE-2024-0822, appears in 4.5.6 and its 4.5.3 backport.

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.

A virtualization manager coasting on backports, with releases years apart

◆ Current state

oVirt Engine's release feed is sparse and slowing: 4.5.5 in late 2023, 4.5.6 and a pair of 4.5.3.x backports in early 2024, then nothing until 4.5.7 in December 2025. Almost every entry is a list of targeted fixes and backports rather than features — OVF import edge cases, template handling, NVRAM save/restore logic, CA generation as a non-root user, Keycloak group handling. One CVE, CVE-2024-0822, appears in 4.5.6 and its 4.5.3 backport.

◆ Where it's heading

This reads as a mature platform in maintenance rather than one being developed. The parallel 4.5.3.x stream exists purely to carry fixes back to deployments that cannot move, and the two-year gap between 4.5.6 and 4.5.7 says more about the project's momentum than any individual change does. Nothing in these entries points toward new capability.

◆ Prediction

The entries do not support a confident call on where this goes next; the only observable pattern is long gaps punctuated by accumulated fix rollups, so another such rollup is the most that can be inferred.

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.
