Starship Combat News has a post about an updated version of the Squadron Strike rules.
From their website:
Squadron Strike is getting a new rulebook, SSD book, and revised and expanded setting book – this is a line refresh that has grown out of answering rules questions on the Ad Astra forum, and taking a chance to add suggestions from users and players throughout the last year and a half. Upgrade kits are available for order.
