| # The purpose of this workflow is to orchestrate Wasmtime's release process as | |
| # much as possible. This specific workflow is responsible for a few timed parts | |
| # of the process: | |
| # | |
| # * On the 5th of every month a new release branch is automatically created and | |
| # the version number of the `main` branch is increased | |
| # * On the 20th of every month the previous release branch is published. | |
| # | |
| # This automation is all done through PRs except for the creation of the release | |
| # branch itself which is an write-action performed by this script. Otherwise | |
| # humans are ideally reviewing and rubber-stamping the output of the script all | |
| # other steps of the way. | |
| # | |
| # Note that this script also helps manage patch releases by sending a PR to the | |
| # release branch with a bumped version number for all crates with a patch-bump. | |
