I'm happy to announce the next release of workflow-ng. You can find the changelog at the release notes.
I think most important are two new features: First of now there is a really useful "Execute arbitrary PHP Code" action and condition, thanks to the awesome GHOP contest. Then now workflow-ng comes with conditions and actions for the path module. This makes even automatic path aliases possible! So if you are interested in a light weight alternative to pathauto, checkout the new tutorial "Automatic path aliases for content".
