Git Latest Release GitHub Action

This GitHub action looks for a commit tagged as "latest" in the current Git repository and tries to determine a version Git tag (one prefixed with "v") for that commit.

In short, if you have a commit which is tagged as "v1.2.5+3", which is also tagged as "latest", this action will return "v1.2.5+3" as its "tag" output.

Additionally, this action also returns just the version number as a dedicated output. In the example above, "version" will contain "1.2.5".
