October 2025 - Harvester UI Extension (harvester/harvester-ui-extension) delivered targeted UI and reliability improvements with a focus on reducing provisioning friction, improving network robustness, and enabling scalable storage operations. Key outcomes include automation of VM type selection via a feature flag, a major UI simplification by removing the old machine type dropdown, and the rollout of volume resizing enhancements with Longhorn v2 gating and online resizing from the VM page. Additionally, critical fixes to VLAN configuration defaults and WebVNC shortcut keys were implemented, alongside a refactor of the Disk component to simplify the disk formatting workflow, improving maintainability and correctness. Business value and impact: - Faster, less error-prone VM provisioning through automation and UI simplification. - More robust networking configuration by defaulting VLAN miimon to -1. - Improved remote console reliability with WebVNC shortcut key fixes. - Greater storage flexibility and reduced downtime via online resizing and feature-flag gated Longhorn v2 support. - Cleaner, more maintainable codebase through targeted refactors.
