* A lot of progress on various aspects of ``numpypy``. See `numpy-status`_
page for the automatic report.
+* It is now possible to create and manipulate C-like structures using the
+ PyPy-only ``_ffi`` module. The advantage over using e.g. ``ctypes`` is that
+ ``_ffi`` is very JIT-friendly, and getting/setting of fields is translated
+ to few assembler instructions by the JIT. However, this is mostly intended
+ as a low-level backend to be used by more user-friendly FFI packages, and
+ the API might change in the future. Use it at your own risk.

* The non-x86 backends for the JIT are progressing but are still not
merged (ARMv7 and PPC64).
