Bugs Fixed

• K8SPSMDB-1274: Revert to disabling MongoDB balancer during restores to follow requirements of Percona Backup for MongoDB 2.8.0.

Known limitations

• PBM-1493: Operator versions 1.19.0 and 1.19.1 have a recommended MongoDB version set to 7.0 because point-in-time recovery may fail on MongoDB 8.0 if sharding is enabled and the Operator version is 1.19.x. Therefore, upgrading to Operator 1.19.0/1.19.1 is not recommended for sharded MongoDB 8.0 clusters.

Supported Platforms

The Operator was developed and tested with Percona Server for MongoDB 6.0.19-16, 7.0.15-9, and 8.0.4-1. Other options may also work but have not been tested. The Operator also uses Percona Backup for MongoDB 2.8.0.

Percona Operators are designed for compatibility with all CNCF-certified
Kubernetes distributions. Our release process includes targeted testing and validation on major cloud provider platforms and OpenShift, as detailed below for Operator version 1.19.1:

• Google Kubernetes Engine (GKE) 1.28-1.30
• Amazon Elastic Container Service for Kubernetes (EKS) 1.29-1.31
• OpenShift Container Platform 4.14.44 - 4.17.11
• Azure Kubernetes Service (AKS) 1.28-1.31
• Minikube 1.34.0 based on Kubernetes 1.31.0

This list only includes the platforms that the Percona Operators are specifically tested on as part of the release process. Other Kubernetes flavors and versions depend on the backward compatibility offered by Kubernetes itself.
