+- loongarch64 TLSDESC support
+- exposed __getauxval for compiler runtime use detecting cpu features
+
+compatibility:
+- initgroups no longer artificially limits number of supplementary groups
+- getusershell now skips blank lines and comments

+- sched.h namespace pollution with _GNU_SOURCE is reduced
+- hasmntopt now matches only whole options, not arbitrary substrings
+- shadow.h no longer declares an unimplemented sgetspent interface
+- vdso with missing sysv hash table (only gnu hash) is now supported

+- lost or delayed wakes in sem_post under race condition
+- termios input speed handling was wrong
+- strcasestr failed to match zero-length needle
+- fma handled corner case with negative zero wrongly
+- syslog LOG_MAKEPRI macro was incorrect
+- timer_create is no longer affected by known pthread_barrier bugs
+- sysconf(_SC_MINSIGSTKSZ) computed min size incorrectly
+- statx emulation left some fields uninitialized
+- mntent wrongly included final newline in parsed field output
+- SIGEV_THREAD timers could abort process if SIGTIMER became unblocked
+- bind_textdomain_codeset returned wrong value
+
+arch-specific bugs fixed:

+- arm and aarch64 crti/n files had wrong alignment
+- m68k POLLWRNORM and POLLWRBAND values were incorrect
+- x32 mq ABI was mismatched
