[Now with correct subject, sorry]

Hi Cygwin friends and users,

I just released Cygwin 1.7.31-1.  This is mostely a bugfix release.

Please note that the new passwd/group handling still isn't in this
version of Cygwin.  The changes are still work in progress.

What changed:

- Improve performance of send(2), sendto(2), sendmsg(2) when using small
  input buffers.
  Addresses: https://cygwin.com/ml/cygwin/2014-07/msg00069.html

- The default pthread_mutex type is now PTHREAD_MUTEX_NORMAL, rather than

- Align pthread_attr stack functions more closely to Linux.

- Mark pthread_attr_getstackaddr and pthread_attr_setstackaddr as deprecated,
  as on Linux.

Bug Fixes

- Fix various assorted bugs (potential buffer overruns, resource leaks, you
  name it) caught by Coverity.

- Fix return value of getgrouplist if the number of groups is bigger than the
  application-provided buffer can hold.
  See https://cygwin.com/ml/cygwin/2014-05/msg00469.html

- Fix a spurious error condition in calls to getaddrinfo on x86_64.
  Addresses: https://cygwin.com/ml/cygwin/2014-06/msg00350.html

- Workaround a problem following native NTFS symlinks.  This patch has been
  not applied to 1.7.30, accidentally.
  Addresses: https://cygwin.com/ml/cygwin/2014-04/msg00384.html

- Fix an off-by-one bug in res_querydomain.
  Addresses: https://cygwin.com/ml/cygwin/2014-07/msg00052.html

- Don't catch STATUS_STACK_OVERFLOW preliminary on 64 bit.
  Fixes: https://cygwin.com/ml/cygwin/2014-07/msg00046.html

- Make sure that signals are properly delivered when sending lots of signals
  in succession.

To install 32-bit Cygwin use http://cygwin.com/setup-x86.exe
To install 64 bit Cygwin use http://cygwin.com/setup-x86_64.exe

The 64 bit Cygwin distribution doesn't yet come with as many packages
as the 32 bit version, but more packages will be available over time.

If you're already running a 32 bit version of Cygwin on 64 bit Windows
machines, you can continue to do so.  If you're planning a new install
of Cygwin on a 64 bit Windows machine, consider to use the new 64 bit
Cygwin version, unless you need certain packages not yet available in
the 64 bit release.

Have fun,
