As reported by engadget,
The two new ships joining the game’s roster are the B-Wing and Tie Defender. The former needs no introduction: it made its first appearance in Return of the Jedi during the climactic final space battle over Endor. The Tie Defender, meanwhile, is more of a deep cut. If you played most of the LucasArts games in the 90s, you’ll recognize the Tie Defender from Star Wars: Tie Fighter.
Outside of the update, EA Motive has also been tweaking how the game’s matchmaking works, with the goal of putting players in games that will end up close without making wait times too long. Star Wars Squadrons creative director Ian Frazier said the studio released several iterations of the same tweak on Friday, with the final one coming out late in the afternoon. For the most part, it seems the tweaking has led to faster queue times — though, as always, some people are complaining that they’ve seen longer wait times. “It’s a tricky balance to hit, so your feedback is welcome,” Frazier said.
