This is the first beta release for pathauto. The main new feature is support for any entity type, you just need to enable it in the settings and then patterns can be added for it. Also includes a number of improvements, for example compatibility when using it with drupal.org's composer repository.
The second alpha release fixes a number of major bugs. It fixes exporting/importing of patterns for specific languages, fixes the manual alias field for entities without a pattern and correctly generates aliases for entities that existed before pathauto was installed. See the full changelog below for details.
