MCK 1.6.1 Release Notes

Bug Fixes

Backed up the agent password in a secret for SCRAM authentication to prevent unnecessary password rotations.
MongoDB Adding missing ownerrefs to ensure proper resource deletion by kubernetes.
Single Cluster Deleting resources created by CRD now only happens on multi-cluster deployments. Single Cluster will solely rely on ownerrefs.
MongoDB, MongoDBOpsManager: Improve validation for featureCompatibilityVersion field in MongoDB and MongoDBOpsManager spec. The field now enforces proper semantic versioning. Previously, invalid semver values could be accepted,
potentially resulting in incorrect configurations.
Roles configured via Ops Manager UI or API will no longer be removed by the operator
A new debug sidecar has been introduced to remove the runtime download of Go and Delve from the agent-launcher script. Instead of enabling agent debugging via the script, debugging is now controlled by the operator. When MDB_AGENT_DEBUG is set to true in the private context, the operator injects a debug sidecar that runs Delve and attaches to the agent process.

A new asset, release_info_<mck-version>.json, is now included with all releases. It documents the latest available versions of all container images used by MongoDB Controllers for Kubernetes at the time of release. This file is provided for informational purposes only and does not define the full support matrix. The format and contents are experimental and may change in future releases, including potential breaking changes for programmatic consumers.
Operator configuration: Removed the unused MDB_IMAGE_TYPE environment variable and the corresponding mongodb.imageType Helm value. This variable was deprecated in v1.28.0 of the MongoDB Enterprise Kubernetes Operator when it switched to architecture-based image selection (ubi9 for static, ubi8 for non-static). This is a cleanup change with no functional impact.
