Appendix A. Migrating from Ranch 2.2 to Ranch 2.3
Ranch 2.3 is a maintenance release containing a small number
of fixes and improvements.
Ranch 2.3 is tested with Erlang/OTP 27.0 onward.
-
Support for Erlang/OTP versions below 27.0 was dropped.
Ranch will now only support Erlang/OTP versions that
receive security patches.
-
Ranch processes now have labels.
-
Unnecessary crash logs were sometimes produced during
PROXY header parsing. This has been addressed.
-
Acceptors now handle
emfile and enfile errors the
same way, instead of just handling emfile. enfile
is the system-wide equivalent of emfile.
