Hi Cygwin friends and users,

I released a new Cygwin TEST version 2.5.0-0.4.

Diffs to -0.3 are mainly bugfixes.

What's new:

- Switch to POSIX ACL API by default.

- First implementation of pthread_barrier/pthread_barrierattr functions.
  New APIs: pthread_barrierattr_init, pthread_barrierattr_setpshared,
  pthread_barrierattr_getpshared, pthread_barrierattr_destroy,
  pthread_barrier_init, pthread_barrier_destroy, pthread_barrier_wait.

What changed:

- In calls to chmod treat ACLs with extra ACEs *only* for Admins and
  SYSTEM like a trivial ACL.

- Bump POSIX option macros to POSIX.1-2008.

Bug Fixes

- Fix potential hang when using LoadLibraryEx(LOAD_LIBRARY_SEARCH_SYSTEM32).
  Reported and tested via IRC.

- Fix a bug in ACL handling which might result in a spurious extra entry
  for the primary group.  Self-observed.

- printf(3): Handle multibyte decimal point in field size computation.

- cygwin_conv_path: Always preserve trailing backslashes in conversion
  to POSIX paths.
  Addresses: https://cygwin.com/ml/cygwin/2016-01/msg00480.html

- Make buffered console characters visible to select().

- Always report relocation problems, not only in debug DLL.
  Addresses: https://cygwin.com/ml/cygwin/2016-02/msg00147.html

- Don't spill network credentials of privileged user changing the user
  context via setuid method 1
  (https://cygwin.com/cygwin-ug-net/ntsec.html#ntsec-nopasswd1) into
  user session

Have fun,
