       Dear all,

a new update of our comparison is available:

https://members.loria.fr/PZimmermann/papers/accuracy.pdf

Main changes in this update:

* we have added compoundn, pown and rootn
* GNU libc is the first library to provide all new C23 functions
* GNU libc now provides 31 correctly-rounded functions in single precision

As for FreeBSD, we saw no big changes between 14.2 and 14.3.
