| # 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. | |

| This is an [automated pull request][process] from CI which indicates that the next [\`release-$cur\` branch][branch] has been created and the \`main\` branch is getting its version number bumped from $cur to $num. | |
| Maintainers should take a moment to review the [release notes][RELEASES.md] for $cur and any updates should be made directly to the [release branch][branch]. | |
| Another automated PR will be made in roughly 2 weeks time when for the actual release itself. | |
| If any issues arise on the \`main\` branch before the release is made then the issue should first be fixed on \`main\` and then backport to the \`release-$cur\` branch. | |
