Release notes

v0.1.12

Summary

Faster replica join for Postgres clusters. Adding a replica no longer waits for a slow checkpoint on the primary.

Highlights

• Replica join is up to minutes faster, most noticeably when adding a replica to a busy live cluster

v0.1.11

Improvements

• Added the ability to choose the MD5 password encryption mode for a specific user (SCRAM-SHA-256 by default).
• Reworked the local database name check: names must now match the Secret/ConfigMap key pattern [._a-zA-Z0-9] instead of an RFC 1123 DNS label (lowercase [a-z0-9] only).
• Preparatory release for the API version increment and the introduction of conversions.

Fixes

• Reworked the automatic password generation approach: with GitOps, hashes are no longer mutated needlessly.
• CVE fixes.

Improvements

• Added validation of database and user names against the Kubernetes requirements for object names.
• Operator pods are now placed on system nodes (if the cluster has any). See the Deckhouse documentation for details.
