+All changes merged into the "main" branch will auto create a "Pre-release" https://github.com/xntrik/hcltm/releases

+To release a new version:
+* Update all the references to the version number to the new version, particularly the [version](version/version.go) file.
+* Update the [CHANGELOG](CHANGELOG.md)
+* Once the main branch has been merged and updated and all the [actions](https://github.com/xntrik/hcltm/actions) are complete
+* `git tag -a vN.N.N -m 'vN.N.N'`
+* `git tag -f latest`
+* `git push --tags`
+* This should then run a "hcltm release" action to release a new version
+* Then don't forget to update https://github.com/xntrik/homebrew-repo
+* And also https://github.com/xntrik/hcltm-action and https://github.com/xntrik/hcltm-action-example

 Thanks,
