Hi Cygwin friends and users,


I released another version of Cygwin.  The version number is 2.3.0-1.


What's new:
-----------

- strftime(3) supports %s (seconds since Epoch) now.

- posix_madvise(POSIX_MADV_WILLNEED) now utilizes OS functionality available
  starting with Windows 8/Server 2012.  Still a no-op on older systems.

- posix_madvise(POSIX_MADV_DONTNEED) now utilizes OS functionality available
  starting with Windows 8.1/Server 2012R2.  Still a no-op on older systems.

- sysconf() now supports returning CPU cache information:
  _SC_LEVEL1_ICACHE_SIZE, _SC_LEVEL1_ICACHE_ASSOC, _SC_LEVEL1_ICACHE_LINESIZE,
  _SC_LEVEL1_DCACHE_SIZE, _SC_LEVEL1_DCACHE_ASSOC, _SC_LEVEL1_DCACHE_LINESIZE,
  _SC_LEVEL2_CACHE_SIZE, _SC_LEVEL2_CACHE_ASSOC, _SC_LEVEL2_CACHE_LINESIZE,
  _SC_LEVEL3_CACHE_SIZE, _SC_LEVEL3_CACHE_ASSOC, _SC_LEVEL3_CACHE_LINESIZE,
  _SC_LEVEL4_CACHE_SIZE, _SC_LEVEL4_CACHE_ASSOC, _SC_LEVEL4_CACHE_LINESIZE

- New API: aligned_alloc, at_quick_exit, quick_exit.

- Add support for Parallels Desktop FS (prlfs).
