v2.4.0 - support local execution with act + allow tags (#40)
* Avoid code repetition with exec() and output listeners * Improve behavior for new branches and when it's running in ACT * Detect parent commit only if needed * Fix parent commit detection for initial commit * Improve logging * Improve current ref detection * Fix issue when base is a already fetched tag * Fix issue when base is a already fetched tag * Update README * Document usage with act * Use `git log` to get changes in latest commit * Disable other output for `git log` * get short name from base ref + improve loggig * update CHANGELOG
