1 What's new:
2 -----------
4 - New API: timingsafe_bcmp, timingsafe_memcmp
6 - New API: dladdr
8 - New API: getloadavg
11 What changed:
12 -------------
14 - cygcheck and strace now always generate output with Unix LF line endings,
15   rather than with DOS/Windows CR LF line endings.
17 - fork now preserves the load order of unrelated dlopen'd modules.
19 - pthread_cond_wait now acts like Linux and BSD: Resume waiting for the
20   condition variable as if it was not interrupted, rather than returning 0.
22 - The internal <sys/_locale.h> header was renamed to <xlocale.h> for
23   source compatibility with other systems.
25 - Try harder supporting Netapp drives.
