       Dear all,

a new update of our comparison is available:

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

Main changes in this update:

* we updated to Newlib 4.6.0

* thanks to Katsuhisa Ozaki, we have updated to MSVC 2026, where several
  issues reported against MSVC 2022 have been fixed

* in double precision, for all C99 univariate functions, at least one library
  now provides a correctly-rounded version, except atan, cosh, sinh, tanh
