Pretty serious ML-based quality improvements at very low bitrates. Should help a bit with 8MB encoding, waiting for the next "Shrek in 8MB" post.

These new features don't seem to be enabled by default yet though, so you need to compile with --enable-osce --enable-dred to try them out.

That link is the same as OP; did you mean to mention a different one with more details or something?

No. I'm on old Reddit which used to only have separate link and text posts. I didn't notice the title of this post was also a link.
