The following packages have been uploaded to the Cygwin distribution
as test releases:

* cygwin-3.3.0-0.2.6c1f49f83fde
* cygwin-devel-3.3.0-0.2.6c1f49f83fde
* cygwin-doc-3.3.0-0.2.6c1f49f83fde

This is the second test release of the upcoming cygwin-3.3.0.  The
only change from the first test release is that there have been
further changes to the internal pipe code.

Please test!


What's new:

- An IP-sampling profiler named 'profiler' has been added.  It can be
   used to profile any Cygwin program along with any DLLs loaded.

- A new tool 'gmondump' has been added.  It can dump the raw
   information of any "gmon.out" file created by profiler, ssp, or use
   of the gcc/g++ option '-pg'.  (Continue using gprof to get symbolic
   profile displays.)

- New GNU-specific APIs, slated to become part of the next POSIX
   standard:  pthread_cond_clockwait, pthread_mutex_clocklock,
   pthread_rwlock_clockrdlock, pthread_rwlock_clockwrlock,

- New Solaris-specific APIs, slated to become part of the next POSIX
   standard:  sig2str, str2sig.

What changed:

- The speed argument to cfsetspeed(3) can now be a numerical baud rate
   rather than a Bnnn constant, as on Linux.
   Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248887.html

- The internal implementation of pipes has been overhauled; this
   should result in improved performance.

Bug Fixes

- Fix values returned by select(2) for shutdown sockets.
   Addresses: https://cygwin.com/pipermail/cygwin-developers/2021-April/012092.html

- Introduce a new hypotl(3) function not suffering unnecessary
   Addresses: https://cygwin.com/pipermail/cygwin/2021-April/248302.html

- Fix path handling for paths spanning native symlinks.
   Addresses: https://cygwin.com/pipermail/cygwin/2021-April/248307.html

- Fix tab position evaluation after console window resize.

- Fix a regression in pseudo console handling, resulting in rlwrap not
   being able to start a new pseudo console.

- Handle two race conditions in pseudo console usage.
   Addresses: https://cygwin.com/pipermail/cygwin/2021-April/248292.html

- Fix a bug in recognizing a successful completion of connect(2) on a
   datagram socket.

- Fix connect(2) when called with an address structure whose family is
   AF_UNSPEC.  As specified by POSIX and Linux, this is allowed on
   datagram sockets, and its effect is to reset the socket's peer

- Fix nanosleep(2) returning negative rem. NtQueryTimer appears to be
   able to return a negative remaining time (less than the timer
   resolution) for unsignalled timers.

- Fix getifaddrs(3) returning address family 0 or IPv4 address 0.
   Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248970.html

- Fix getaddrinfo(3) to return valid ai_socktype and ai_protocol
   values if the underlying GetAddrInfoW screws up.
   Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248985.html

- Fix duplicate /proc/partitions entries and (presumably) duplicate
   PIDs in ps(1) output.
   Addresses: https://cygwin.com/pipermail/cygwin/2021-July/248998.html


Have fun,
