Hiya - all our newest fonts are included in the All Fonts Pack license, although the AFP download itself may not have yet been updated to include them. By all means download those newer fonts from FontSpace or DaFont and use them in the same commercial ways, regardless of when you purchased AFP!
(We generally save the AFP download updates for several fonts in a row due to our frequent releases of new ones)
Newest fonts we have made that were released since AFP but are still licensed by it: Moustache You; Half Myself; Manic Germanic; Swansong; Blaze of Glory; Spirit Fox; Spiced Rum Supernova; Tiny and Chunky; Punk Metal; The Visitor; Devious Road; Robinson Pleasure; Cynosure; Liquid Crystal Decay; Overthrow Oligarchy; Guardian Angle; Nuchileda; CI GameDev 16px; Tempter; Bees Chubees; Infinitely Grateful; Riot City Revolts!.
