Features and Improvements

No notable features in this patch release.

Fixes

• fix(cluster-api): fix kamaji OOM and set limits on unset providers: The resource override for the kamaji control-plane-provider was silently ignored because the override targeted containers[name=manager] while the upstream container is named controller. The CAPI operator merges container overrides by name, so the intended cpu: 1 / memory: 1024Mi limits were dropped and the upstream default of 128 MiB was applied, causing the kamaji controller to restart repeatedly with OOMKilled (exit code 137). Adds the correct container name and also sets modest resource requests and limits for the core, kubeadm-bootstrap, and kubevirt-infrastructure providers that previously ran BestEffort and were first to evict under memory pressure (@myasnikovdaniil in [#2708], backport [#2710]).

• fix(kafka): reclaim ZooKeeper PVCs on Kafka release deletion: Sets deleteClaim: true on the ZooKeeper persistent-claim storage so the Strimzi operator removes ZooKeeper PVCs together with the rest of the cluster when the Kafka CR is deleted, matching the existing behavior for Kafka broker PVCs. Previously, ZooKeeper PVCs were orphaned in the tenant namespace and required manual cleanup before the same release name could be reused (@Arsolitt in [#2679], backport [#2706]).

• fix(opensearch-operator): replace deprecated kube-rbac-proxy image: Replaces the broken gcr.io/kubebuilder/kube-rbac-proxy:v0.15.0 image (the GCR kubebuilder registry was sunset and the image no longer pulls) with quay.io/brancz/kube-rbac-proxy:v0.15.0, the same image already used elsewhere in Cozystack (e.g., etcd-operator), restoring OpenSearch operator pod startup (@myasnikovdaniil in [#2689], backport [#2696]).

Documentation

• [website] feat(home): refresh screenshot gallery with new captures: Replaces the previous dual light/dark screenshot carousel with 14 single-mode captures of the updated Cozystack dashboard, removes the light/dark mode toggle, and improves carousel navigation with high-contrast circular arrows and overlay indicator dots (@kvaps in cozystack/website#543).

• [website] feat(blog): announce /cozystack:wizard guided installer: New blog post announcing the /cozystack:wizard guided end-to-end installer that handles Talos, Ubuntu, and existing-cluster deployment flows, including edge cases such as cert-SAN traps on NAT'd clouds, ZFS on Talos, LINSTOR registration races, and boot-to-Talos upgrades (@tym83 in cozystack/website#542).

Other repositories

• [ansible-cozystack] chore(deps): update k3s dependency to v1.36.0+k3s1: Bumps the k3s Kubernetes distribution dependency to v1.36.0+k3s1 in the ansible-cozystack role (@app/renovate in cozystack/ansible-cozystack#41).

• [ansible-cozystack] chore(deps): track cozystack installer v1.4.0 and v1.4.1: Renovate dependency bumps of the cozy-installer Docker image tag to follow the latest Cozystack installer releases (@app/renovate in cozystack/ansible-cozystack#42, [#44]).
