@ -55,6 +55,11 @@ Major new features:
flags and a non-existing destination (and therefore has a race condition
that can clobber the destination inadvertently).
* The statx function has been added, a variant of the fstatat64
function with an additional flags argument. If there is no direct
kernel support for statx, glibc provides basic stat support based on
the fstatat64 function.
* IDN domain names in getaddrinfo and getnameinfo now use the system libidn2
library if installed. libidn2 version 2.0.5 or later is recommended. If
libidn2 is not available, internationalized domain names are not encoded
