v1.8 First general release of ESP8266 port, and support for frozen bytecode
This release marks the first general release of official ESP8266 support
within the MicroPython code base. The ESP8266 port has many improvements
and additions, including: websocket and webrepl modules, deep-sleep mode,
reading on UART, enhanced I2C support, enhanced network configuration,
full sequence of start-up scripts (built-in _boot.py, boot.py and
main.py), improved filesystem support with automatic flash-size detection
as well as documentation and a tutorial.
Known issues with ESP8266 port are:
- Basic SSL support is available but it works only with relatively short
data lengths (a few kilobytes).
- WebREPL over SSL is not supported.
- Only 5 or so WebREPL sessions in succession can be started (including
file transfer sessions), after that the board requires a hard reset.
- File transfer over WebREPL has issues with large files (above a few
tens of kilobytes).
- By design, only one concurrent WebREPL connection is supported.
- Soft reset doesn't reset the network stack.
In addition to ESP8266 support, this release brings frozen bytecode
which allows to compile bytecode offline and link it into the firmware,
completely eliminating the need for compilation (and the associated
RAM usage) at runtime. Basic async/await syntax is now supported, and
qstrs are now auto-generated in the build system.
A detailed list of changes is given below.
README:
- explicitly point to required dependencies section
- promote "docs" and "tests" to "major components"

最大变化就是开始正式支持ESP8266了，以后我们可以用MicroPython玩玩Wifi和网络了。
此外我发现的在NUCLEO开发板上的I2C1问题也修复了。

重温一下git。我一直是直接下载zip file，总是拿不到最新的patch。
