However there is a lot of new stuff in this new version: * the Microsoft math library is now included (it was clearly missing) * we also added the FreeBSD math library * and we added some new C23 functions (acospi, cospi, ...) which are available in the Intel and FreeBSD math libraries (but not yet in glibc) Paul Zimmermann
