+* Support module-level docstrings
+* Initial support for the `venv` standard-library tool
+* Initial support for the built-in `_bz2` module
+* Initial support for the `pandas` package
+* Initial support for OSError subclasses based on the `errno` of the exception
+* Fix bytearray inplace add to return the same object
+* Fix access to standard Python methods (`__repr__`, `__str__`, `__len__` and the like) for foreign objects
+
 ## Version 1.0.0 RC11
 
 * Support running setuptools to build and install various packages

@@ -36,6 +36,15 @@ If all goes well (you'll need to have `clang`, `llvm-link`, `llvm-extract`,
 `llvm-nm`, and `opt` in your `PATH` in addition to the normal NumPy build
 dependencies), you should be able to `import numpy` afterwards.
 
+Support for more extension modules is high priority for us. We are actively
+building out our support for the Python C API to make extensions such as NumPy,
+SciPy, Scikit-learn, Tensorflow and the like work. This work means that some
+other extensions might also already work, but we're not actively testing other
+extensions right now and cannot promise anything. Note that to try extensions on
+this implementation, you have to download, build, and install them manually for
+now. To do so, we recommend LLVM 6. Other versions might also work, but this
+version is what we're testing with in our CI.
