u/raithosu over on Reddit has done the hard work of porting YASB over to Xwing 2.0. The builder is probably 90% done, there are still some glitches and some info that doesn't show, but it's very useable right now.

Here is his commentary from Reddit, if you do find any issues I'd recommend posting in the reddit thread.

Hi everyone, with /u/geordanr deciding not to do a 2.0 version of YASB, I decided to take it on myself, as it's the best list builder. I decided to make a new one instead of submitting updates for the old one since people are still using 1.0. The conversion isn't perfect, but its servicable enough now that you can actually use it to build lists without too much trouble. It's a work in progress so if you catch any bugs outside of the known issues please post it here! I had a bunch of PTL'ers help identify bugs but theres only so many eyeballs. It's just me working on stuff right now mainly. Shoutouts to the PTL who have helped convert all the ships and upgrades to 2.0
Known Issues:
Some icons dont show up, like target locks, force icons, and some single turret arcs
Combo actions dont show the second part as red
Charge stats are not in the files yet
Cost requirements on variable upgrades are set at the lowest value but calculate correctly
Secondary Weapons don't have the special arc visually showing yet in the attack stat
