This release adds the qsort_r function (POSIX future) and several minor extension interfaces, and support for the alternative SPE FPU present on some PowerPC CPU models.
Notable bugs fixed include an old regression in wcwidth of Hangul combining vowels and finals, a 1.2.2 regression breaking duplocale when malloc is replaced, null-dereference crash of aligned allocation functions on underlying malloc failure, out-of-bounds timezone data read when handling distant-past timestamps, longstanding incorrect dl_iterate_phdr reporting of module TLS pointers, and several math library bugs that resulted in wrong results for some inputs, including incorrectly-rounded fmaf on all softfloat archs.
Many non-bugfix compatibility improvements have also been made, including having free preserve errno (POSIX future requirement), better TZ environment variable handling, and having gettext accept null message pointer (returned unchanged).
