Usage: ./version_tag.sh [--dry-run] [--old-version <version>] [--ref <ref>] <--major | --minor | --patch>
|
|
|
|
This script should be called to tag a new release. It will take the suggested
|
|
increment (major, minor, patch) and optionally promote e.g. patch -> minor if
|
|
there are breaking changes between the previous version and the given --ref
|
|
(or HEAD).
|
|
|
|
Pass --old-version optionally to ensure that the version is bumped from the
|
|
provided version instead of the latest tag (for use in release.sh).
|
|
|
|
This script will create a git tag, it should only be called by release.sh or in
|
|
CI.
