Highlights:

  • More work on C2X features.

  • The strlcpy and strlcat functions have been added. They are derived from OpenBSD, and are expected to be added to a future POSIX version.

  • Support for x86_64 running on Hurd has been added.

  • CVE-2023-25139: When the printf family of functions is called with a format specifier that uses an (enable grouping) and a minimum width specifier, the resulting output could be larger than reasonably expected by a caller that computed a tight bound on the buffer size. The resulting larger than expected output could result in a buffer overflow in the printf family of functions.
