Musl 1.2.4 adds TCP DNS fallback

musl 1.2.4 has been released, addressing some long-standing issues and making several improvements. One notable fix is the addition of TCP fallback to the DNS stub resolver, allowing for queries of large DNS records and compatibility with recursive nameservers that don’t provide partial results in truncated UDP responses. The release also includes bug fixes and improvements in DNS functionality, including the differentiation between NODATA and NxDomain conditions in the API results. Additionally, the release deprecates the legacy “LFS64” interfaces and introduces support for the new compact “RELR” format for relative relocations in the dynamic linker. Various bugs have been fixed, including those in printf functions, strverscmp, and thread synchronization logic.
