Tametsi Beta branch

There is a new beta branch available. It is identical to the main branch, except that it prefers to use an existing Java installation instead of the OpenJDK that is bundled with Tametsi.

This is a potential fix for a few users who have reported a crash upon launch. There is no reason to use this branch if you aren't experiencing this specific issue.

Players who opt in to this branch will see the version number appear as "1.79b". For anyone trying this out, please share feedback!
