5.77 is now available on Steam alpha (all platforms) and for Windows standalone.
No new features but this build significantly reduces RAM usage required for replay cache, fixes a bunch of memory leaks and should generally improve performance due to various internal optimizations.

Keep in mind that this update is experimental and didn't go through the regular testing process, so it's entirely possible that it will introduce a whole range of all-new and never-seen-before bugs. Or it won't.

Android build might also become available as an open beta some time in the coming days depending on Google review process.
