Bug Fix(es) and Enhancement(s):

  • The iconv utility no longer returns exit status 1 after a successful //TRANSLIT transliteration

  • A counter overflow in __wcsmbs_clone_conv that occurred when setlocale was called has been fixed

  • A fcntl.h header conflict when compiling on Rocky Linux 10 has been resolved

  • Minor documentation improvements have been picked up from upstream
