Hello,
MicroPython is a Python3 language implementation which scales down to run on microcontrollers with tens of Ks of RAM and few hundreds of Ks of code size. Besides microcontrollers, it's also useful for small embedded Linux systems, where storage space is limited, for embedding as a scripting engine into standalone applications, where quick startup time is needed, etc.

It went several months since the original announcement of MicroPython 1.0 (https://mail.python.org/pipermail/python-list/2014-June/672994.html), there were number of releases in the meantime, but we were too busy implementing new features, so this announcement provides just high-level overview of changes:
- Basic Unicode support added (thanks to Chris Angelico for driving the effort)
- More functionality of standard types and functions are implemented (for example, MicroPython can run subset of http.client module functionality from CPython3 stdlib).
- Highly optimized for code size implementations of important Python modules are added. There offer subset of functionality and prefixed with "u". For example, ure, uheapq, uzlib, uhashlib, ubinascii are provided.
- Lots of microcontroller hardware bindings added and generalized.
Besides core interpreter, there's also good progress on modules and applications:
- MicroPython standard library project, https://github.com/micropython/micropython-lib , an effort to port/develop as much as possible Python stdlib modules to MicroPython, has good progress, with few dozens of modules available on PyPI already (pip-micropython wrapper is provided to install them).
- An asyncio subset implementation, dubbed "uasyncio", is available and should be stable enough.
- Proof of concept web microframework, "picoweb", based on uasyncio is being developed: https://github.com/pfalcon/picoweb
- Lots of other projects available on github.
Reference implementation of MicroPython runs on a microcontroller board with 1Mb Flash and 128Kb RAM, which should offer good platform for people interested in microcontroller usage (more info: http://micropython.org/). MicroPython can also be easily built and supported on Linux, MacOSX, and Windows systems (more info: https://github.com/micropython/micropython)
