New Composite Rules for Doomtown Reloaded are published on the AEG website - that's the basic rulebook plus additional rules from expansions (Experienced, Cooperatin') and errata (Jia Mein Reversal, acing as a cost, additional requirements on jobs, etc.). Unfortunately, the new sections are not marked with red color.
The corresponding sections were removed from the new FAQ. v.4, and many recent rulings were added.
Tournament Floor Rules also got updated, but it's not obvious what's actually new there (besides the reversal on the timing of grifters)
@platypus Please add this to dtdb.co when you get a chance. Thanks
