Aug 1, 2025In August 2025, vm-operator delivered significant enhancements to VM placement reliability, API compatibility across versions, and safer snapshot workflows, along with cross-zone backup stability. Key items include zonal VM affinity/anti-affinity enhancements with label selectors and MatchExpressions, API backports to support v1alpha2/v1alpha3 for VM affinity types, and broader compatibility for VirtualMachineGroup APIs across versions. Additionally, snapshot management improvements ensure reconciliation is triggered by snapshot events while preventing risky operations during active reverts and snapshot tasks. Zone-aware VM backup handling was fixed by removing zone annotations and applying zone labels dynamically on VM registration, with corresponding test updates. These changes reduce misplacement risk, improve consumer API stability, and enhance cross-zone operational safety for customers.

Jul 1, 2025July 2025 — VM Operator: Delivered declarative VM snapshot capabilities, enhanced lifecycle management, and codebase cleanup, delivering measurable reliability and declarative automation benefits for VM snapshots. Features include a capability flag for VM snapshots with conditional enablement, revert-to-snapshot support, CRD-driven snapshot workflow with centralized management and owner references, and removal of obsolete VM class controller code. A bug fix corrected the field updated during snapshot creation by updating vm.spec.currentSnapshot instead of vm.status.currentSnapshot. These changes improve automation, reliability, and maintainability, enabling declarative snapshot management, robust ownership semantics, and simplified configuration.
