The CloudNativePG Community is pleased to announce the release of CloudNativePG 1.26.0 RC3, the third release candidate before general availability.

This release delivers important fixes identified during the first wave of large-scale testing—particularly in two critical areas:

the transition from in-tree Barman Cloud object store support to the new plugin-based architecture, and
the major version upgrade process.

Read the full changelog in the 1.26.0 RC3 release notes.

Barman Cloud Migration

With the 1.26 release, the deprecation period for in-tree Barman Cloud support officially begins. While it remains fully functional in 1.26, we strongly encourage users to begin planning the migration to the Barman Cloud Plugin as early as possible and to adopt it for all new deployments.

To help with this, we’ve published a comprehensive migration guide— and this RC is the perfect opportunity to test it out and share your feedback.

Also, a warning will now be triggered by the admission webhook when using the deprecated .spec.backup.barmanObjectStore and .spec.backup.retentionPolicy fields.

New Experimental Feature: Primary Liveness Network Isolation

RC3 introduces an opt-in experimental enhancement to the liveness probe that enables detection of network isolation scenarios for primary instances. When enabled via the alpha.cnpg.io/livenessPinger annotation, this feature allows a primary that is isolated to proactively shut itself down.
