The latest musl source is always available via the git revision control system. Efforts are made to keep the master branch in a state that not only compiles and works, but that works at least as well or better than the latest release.
The following command can be used to checkout a copy of the musl git repository:
$ git clone git://git.musl-libc.org/musl
Source and revision history are also browsable online via cgit.
musl generally follows a time-based release cycle, with versions spaced roughly one to three months apart. Version numbering, however, is based on an evolving roadmap for particular compatibility and feature goals. Releases are timed so as to make fixes for major bugs available in release form as soon as possible while leaving ample time for testing after significant invasive changes.
See below for release notes summaries and download links.
This series is actively developed but intended for use in production environments as long as appropriate testing is performed.
This release features major new iconv functionality including support for stateful encodings (so far, ISO-2022-JP and UTF-16/32 with BOM-determined endianness), conversion to JIS-based Japanese encodings (previously only from direction was supported), EBCDIC codesets (so far IBM1047), and DOS Cyrillic (CP866). Character data has been updated for alignment with Unicode 10.0. The fopencookie stdio extension function and strftime padding extensions have been added, and many smaller compatibility improvements and bug fixes have been made.
Earlier versions of musl have been moved to a separate page.
