Its major user-facing new properties are the ability to return freed memory on a much finer granularity and avoidance of many catastrophic fragmentation patterns. In addition it provides strong hardening against memory usage errors by the caller, including detection of overflows, double-free, and use-after-free, and does not admit corruption of allocator state via these errors. Other enhancements in this release include changes to the res_* API to report DNSSEC status of the results (needed for correct implementation of DANE in applications) and new arch-specific optimized string and math functions, especially memcpy and memset for AAarch64. A major logic/synchronization error in lock skipping after a multi-threaded process returns to single-threaded state has been fixed, along with a number of lesser bugs, including some time64-related regressions on 32-bit archs. One of these was actually a kernel vdso bug that broke clock_gettime on arm on hardware where the vdso should not be used; as a result, arm vdso support has been disabled until there is a reliable and inexpensive way to detect whether it's safe to use. Bugs and recent regressions affecting all mips archs and other arch-specific bugs have also been fixed. https://musl.libc.org/releases/musl-1.2.1.tar.gz https://musl.libc.org/releases/musl-1.2.1.tar.gz.asc Special thanks to musl's release sponsors who have supported the project financially over this release cycle via Patreon and GitHub Sponsors at the $32/month level: * Justin Cormack * Nathan Hoad * Jeremiah Gowdy * Mirza Prasovic * Hurricane Labs (hurricanelabs.com) * Les Aker * Neal Gompa * The Midipix Project (midipix.org) * Laurent Bercot * Michael Forney * Andrew Kelley / ziglang * Bartosz Brachaczek * Noel Cower * Evan Phoenix * Jonny For information on becoming a sponsor, visit one of: https://github.com/sponsors/richfelker https://patreon.com/musl
