Virtually all major systems in the game have been internally changed. The passage of time is a lot more complicated, and you might have to pass the argument 'nothreads' if your pc doesn't agree- but it should be fine. Of particular note, Attacks and Exotic Arts had changes but not enough time to refill their content (which is a recurring issue in Trawel, however this time it was for a different reason than normal- kernel upgrade issues nearly prevented this update entirely). As per normal, this beta is Windows only, but it probably runs in proton, and if you want you can snag the jar and try to get it working yourself. The biggest barrier to updating linux has been the Graphical, and the new engine will likely have no such issues staying up-to-date, but that's still a ways away. (I was able to somewhat get it working on my own machine, but reliability issues prevent me from being able to push it directly.) You can check out the roadmap here. Remember to report issues in the steam forums or in the github issue tracker! You can find instructions on how to opt-in to Steam betas in the full beta announcement which will be made shortly after this post. Priorities besides finding crashing are giving feedback on the state of damage vs armor balance, which is currently unknown, and needs work. We're at the point where we don't know if armor is too strong or too weak. Attributes also got somewhat added, and they properly replaced dodge multiplier on armor, however once again their other interactions are limited. Expect a focus on finishing the transfer of attack backend, and then a shift to the classless system, over the next week. (PS: giant pants bug might be fixed!)
