The compression code is stable (it's from stable LZMA SDK).
"Beta" refers mostly to the command line tool. It never got all the
features that were planned, because development switched to a new
branch, which has been under development over a year now. As a result,
the old 4.32.0betas branch were left to be called betas.
The alpha versions have nothing stable, not even the core of the
compression code. Don't trust them. They are there only for testing.
The 4.32.0betas have been used by a few (small) GNU+Linux distros as
part of the package management (all packages compressed with LZMA).
LZMA has worked reliably in all situations that I'm aware. The command
line tool has had some minor bugs (no data corruption bugs) but those
have been fixed.
The biggest problem is that the current .lzma format doesn't have any
integrity check. If a few bits flip in the compressed file, it may go
undetected especially if the flipped bits are near the end of the file.
This will be fixed in the new .lzma format, but there are no stable
tools to handle that format yet.
