The plugins typically have a version number with a letter behind it which indicates the state of the plugin. The letters should be interpreted as follows:
- α - Alpha:
Pre-release, probably untested and unstable (don't use in production)
- β - Beta:
Initial release, may have been tested and should be reasonably stable (not recommended for production usage)
- γ- Stable:
Full release, should be fully tested and stable (production ready)
