Release Notes: This is the first release of musl to support building native x86_64 applications, and it features a source/build framework for additional ports. Some public header errors introduced in the previous release have been fixed, as well as a major bug in the %n specifier for printf and several minor bugs.
Release Notes: This release fixes a major bug in the intended long-term ABI for sigset_t/sigaction. Anyone using musl to build libraries should upgrade immediately (and rebuild any libraries which might use signals) to avoid running into ABI breakage issues at a later time. The public header files have also undergone review and correction for conformance to ISO C and POSIX requirements for what they are allowed to make visible. Various other minor bugs have been fixed, and internal improvements have been made to facilitate upcoming ports to x86_64 and possibly ARM.
Release Notes: Initial public release.
