Description

A recent commit (02e93192) switched the runner version for the action to node20 from node16. On our self-hosted Github Enterprise server, this results in actions failing with the error.

Expected behaviour

Ideally, a change to the runner to a newer version that is possibly unsupported everywhere would be tagged with a new label (e.g. no longer v3.0.0) so we could continue to use the supported version.

Actual behaviour

Our actions are failing with an error:

Error: System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. (Parameter ''using: node20' is not supported, use 'docker', 'node12' or 'node16' instead.')

   at GitHub.Runner.Worker.ActionManifestManager.Load(IExecutionContext executionContext, String manifestFile)
Error: Fail to load docker/setup-buildx-action/v3/action.yml

So this may have been filed a little prematurely: we updated our Github actions runner image from v2.306.0-ubuntu-20.04 to v2.309.0-ubuntu-20.04 and node20 is accepted now.

@wrose504 Yes as said in the release notes it requires a minimal version of the runner: https://github.com/docker/setup-buildx-action/releases/tag/v3.0.0

... (requires Actions Runner v2.308.0 or later) by @crazy-max in https://github.com/docker/setup-buildx-action/pull/264

That's why this is a major release.
