 > [!NOTE]
-> When using latest version you might hit the GitHub GraphQL API hourly rate limit of 5,000. The action will then return the hardcoded default stable version (currently v3.13.3). If you rely on a certain version higher than the default, you should use that version instead of latest.

 The cached helm binary path is prepended to the PATH environment variable as well as stored in the helm-path output variable.
