What's new:
-----------
- Drop support for Windows 7, Windows 8, Server 2008 R2 and Server 2012.
- The console device gets accessible from other terminals such as other
consoles and ptys. Thanks to this new feature, GNU screen and tmux
now work in the console.
- newgrp(1) tool.
- cygcheck has new options searching for available packages in the
cygwin distro, as well as getting extended info on available and
installed packages.
- fnmatch(3) and glob(3) now support named character classes, equivalence
class expressions, and collating symbols in the search pattern, i.e.,
[:alnum:], [=a=], [.aa.].
- Introduce /proc/codesets and /proc/locales with information on
supported codesets and locales for all interested parties. Locale(1)
opens these files and uses the info for printing locale info like any
other process could do.
- Add support for GB18030 codeset.
- Add support for lseek flags SEEK_DATA and SEEK_HOLE, a GNU extension.
- New API calls: posix_spawn_file_actions_addchdir_np,
posix_spawn_file_actions_addfchdir_np.
- New API calls: c8rtomb, c16rtomb, c32rtomb, mbrtoc8, mbrtoc16, mbrtoc32.
- Implement OSS-based sound mixer device (/dev/mixer).
What changed:
-------------
- posix_spawnp no longer falls back to starting the shell for unrecognized
files as execvp. For the reasoning, see

- FIFOs now also work over NFS.
