-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 main remaining applications
-which definitely will not work are those which require C++ support,
-which will be addressed during the 0.8 or 0.9 development series.
+With the 0.9.0 release, musl has reached a milestone in completeness
+and compatibility. All interfaces in ISO C99 and POSIX 2008 base exist
+in musl, along with a number of non-standardized interfaces based on
+GNU and BSD libraries and syscall interfaces for Linux-kernel-specific
+functions. Some interfaces lack obscure or rarely-used functionality
+needed for strict conformance, but the vast majority of interfaces go
+above and beyond the requirements for conformance, often promising
+success where other implementations can fail under resource exhaustion
+or other corner-case conditions.
+
+At this point, hundreds of packages have been successfully built
+against musl - either out-of-the-box or with minor patches to address
+portability errors - ranging from low-level system utilities and
+network daemons to major gui applications. Testing has been conducted
+using three separate test frameworks and numerous additional
+standalone test cases to verify the correctness of the implementation.
