This release introduces the ability to replace/interpose the allocator (malloc) subject to certain restrictions, adds an experimental m68k port, and makes notable improvements to stdio (application-provided buffers), getaddrinfo (AI_ADDRCONFIG, support for IPv4-only kernel configurations), the dynamic linker (safety against dlopen of libraries using initial-exec TLS model, reclaiming unused memory on FDPIC archs, better dladdr results), and handling of default thread stack size (pthread_setattr_default_np now works more reliably). Many bugs have been fixed, including potentially dangerous regressions in iconv (only for new conversions to legacy encodings) and visibly incorrect behavior in printf on non-x86 archs (%a format with precision specifier), in getopt_long_only when short options are a prefix for a long option, in complex arc-trig/hyperbolic functions, in strftime and mktime (timezone-specific issues), and numerous less-obvious places.
