Is there anywhere to track the progress of the new GC system? Freezing tends to interfere with other thread-safe methodologies (as the original article on freezing suggests), so the fact that the K/N team suggested that the new GC will not require freezing is helpful. In May, they estimated a dev preview would be available by end of Summer, which is getting close.

It's not documented but you can try it out in 1.5.30-M1. Need to pass

-memory-model experimental

as compiler args

Thank you. I'll try this out. Do you happen to know where you found out about this arg? I'd like to be able to track the progress of this.

If you want to watch a ticket, I don't know anything better than the roadmap at https://youtrack.jetbrains.com/issue/KT-42296 which doesn't go into detail. I found the flag from a mention in a coroutines issue somewhere. I expect we'll hear more about it closer to 1.5.30 release but we'll see
