[ANNOUNCEMENT] cygwin 3.3.0-0.1.9814cfd8f693 (TEST)
Sat Sep 18 19:03:15 GMT 2021
I'm not sure how to try out a test release without risking destabilizing my system, but I re-cloned and rebuilt the master branch and installed just the cygwin1.dll and all looks good to me so far. No issues with any of my script pipes or fifos and I am getting full gigabit speeds with rsync.
I too have been following all the pipe rework on Cygwin-developers and want to express my appreciation for Takashi, Ken and Corinna for tackling this. You folks have made Cygwin so much more usable for a lot of applications!
