Automated Release Process #86

Automated Release Process

Automated Release Process #86

# 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 $cur, and if any changes are necessary send
PRs to the \`main\` branch to update [RELEASES.md] and then backport
these PRs to the [release branch][branch].
Maintainers should also review that aarch64-apple-darwin builds
are passing via [embark's CI](https://buildkite.com/embark-studios/wasmtime-aarch64-apple-darwin).
Another automated PR will be made in roughly 2 weeks time when for
the actual release itself.
If any issues arise on the \`main\` branch before the release is made
then the issue should first be fixed on \`main\` and then backported
to the \`release-$cur\` branch.

This is an [automated pull request][process] from CI which is
intended to notify maintainers that it's time to release Wasmtime
$cur. The [release branch][branch] was created roughly two weeks ago
and it's now time for it to be published and released.
It's recommended that maintainers double-check that [RELEASES.md]
is up-to-date and that there are no known issues before merging this
PR. When this PR is merged a release tag will automatically be
created, crates will be published, and CI artifacts will be produced.
