|3.2.0||Mar 30, 2021||New Release||What's NEW:
Revamped pseudo console support. Conditionally activating it only when a non-cygwin application is run.
New C11 threads API: call_once, cnd_broadcast, cnd_destroy, cnd_init, cnd_signal, cnd_timedwait, cnd_wait, mtx_destroy, mtx_init, mtx_lock, mtx_timedlock, mtx_trylock, mtx_unlock, thrd_create, thrd_current, thrd_detach, thrd_equal, thrd_exit, thrd_join, thrd_sleep, thrd_yield, tss_create, tss_delete, tss_get, tss_set.
In cygwin console, new thread which handles special keys/signals such as Ctrl-Z (VSUSP), Ctrl- (VQUIT), Ctrl-S (VSTOP), Ctrl-Q (VSTART) and SIGWINCH has been introduced. There have been a long standing issue that these keys/signals are handled only when app calls read() or select(). Now, these work even if app does not call read() or select().
Fchmodat(2) now has limited support for the AT_SYMLINK_NOFOLLOW flag.
Cygwin now recognizes native Windows AF_UNIX sockets (as regular files, not as socket files). This allows tools like 'ls' and 'rm' to work.

Fix a buffer overrun in Cygwin-internal string comparison.
