Harvester v1.5.1 Release Notes

This release introduces several features, enhancements, and bug fixes that improve system quality and the overall user experience. The documentation is available at https://docs.harvesterhci.io/v1.5.

The Harvester team appreciates your contributions and looks forward to receiving feedback regarding this release.

[!CAUTION]

Rancher Kubernetes Engine (RKE) will reach the end of its life on July 31, 2025. Harvester v1.6.0 and later versions will not support RKE. Switching to RKE2, which provides a more secure and efficient environment, is recommended.

In-place upgrades are not an option, so you must create new RKE2 clusters and migrate the workloads from your existing RKE clusters (known as replatforming). For more information, see RKE End of Life.

Installation

Harvester can be installed using the ISO image, a bootable USB drive, and PXE boot. For more information, see the Installation section of the documentation.

[!IMPORTANT] The Harvester v1.5.1 installer checks if the hardware meets the minimum requirements for production use. If any of the checks fail, installation is stopped and warnings are printed to the system console.

You can disable this behavior during iPXE installation (for testing purposes) by adding the kernel parameter harvester.install.skipchecks=true when you boot the system. For more information, see Useful Kernel Parameters.

Upgrade

Harvester only allows upgrades from supported versions. For more information about upgrade paths and procedures, see Upgrading Harvester.
