I'm happy to announce the rules 6.x 1.0 BETA 1 release. Check out the rules project page and try it. Now the API is frozen and modules developers are encouraged to write module integration and to port their workflow-ng integration to rules. You can find the documentation here.
To get token support everywhere in your actions you just have to install the latest development snapshot of it.
Now basically everything is there, including support for
- firing core actions
- grouping rules in rule sets
- scheduling arbitrary rule sets
- a module input evaluation system
- and much more!
