# The release flow is the following.
#
# 1. push transpiled TypeScript files into the releases/v1 branch
# 2. create new tag v1.x.x on releases/v1 branch
# 3. trigger workflows for building MySQL binaries
# 4. move v1 tag to v1.x.x
#
# ./prepare.sh does No.1 and 2, and ./release.sh does No.4
#
# 1. run `./prepare.sh 1.0.0`
# 2. wait for all actions to finish. https://github.com/shogo82148/actions-setup-mysql/actions
# 3. run `./release.sh 1.0.0`
# 4. publish new release on GitHub https://github.com/shogo82148/actions-setup-mysql/releases
