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, and should be preferred whenever there is a need for supporting an arbitrary, expanding set of packages or environments.
musl-1.1.4.tar.gz - Jul 31, 2014
This release features a new port to the OpenRISC 1000 (or1k) architecture, experimental support for locale in the LC_MESSAGES and LC_TIME categories, and a built-in implementation of the gettext system for message translations. Numerous bugs have also been fixed, including a regression in the dynamic linker that prevented it from showing error messages, incorrect memory synchronization/barriers on microblaze, mips, powerpc, and sh, problems with the struct stat layout on microblaze and big-endian mips, a serious setjmp register state corruption bug on microblaze, a dynamic linker regression on mips, and various minor issues. In addition, a workaround is provided for gcc bug 61144 which prevented building musl with gcc 4.9.x.
This series does not add new features and avoids changes that might affect building packages against musl or using applications in environments where they are already known to work. It is intended mostly for developers targetting a fixed profile of application software and kernel, such as in embedded development.
musl-1.0.4.tar.gz - Aug 1, 2014
This maintenance release brings the 1.0 branch up to date with all important bug fixes that have been applied to mainline as of 1.1.4. These include a major logic bug in memmem which yielded both false negatives and false positives, numerous issues that were specific to mips, powerpc, and microblaze, and various other lower-severity bugs.
Earlier versions of musl have been moved to a separate page.
