-As of the 0.8.0 release, musl is in _beta_ status. While some
-interfaces remain incomplete or yet to be implemented, the ABI is
-intended to be stable at this point, and serious efforts have been
-made, using three separate test frameworks, to verify the correctness
-of the implementation. Many major system-level and user-level programs
-are known to work with musl, either out-of-the-box or with minor
-patches to address portability errors.
+The 0.9.x release series for musl features interface coverage for all
+interfaces defined in ISO C99 and POSIX 2008 base, along with a number
+of non-standardized interfaces for compatibility with Linux, BSD, and
+glibc functionality. As the release series progresses, we are
+gradually adding support for incomplete functionality in existing
+interfaces, additional functions that are deemed to be important due
+to their use in real-world software, and support for new library and
+language features in C11 such as thread-local storage, which is now
+supported on all targets. In addition, support for additional target
+cpu architectures is being added.
+
+The number of packages build successfully against musl - either
+out-of-the-box or with minor patches to address portability errors -
+has exceeded 5000 and is steadily growing. In addition to application
+compatibility testing, unit testing has been conducted using three
+separate test frameworks and numerous additional standalone test cases
+to verify the correctness of the implementation.
