Daily builds of the code (the stmhal/ directory) are available below. The hardware version of the board that you have should be written on your pyboard; eg boards with PYBv1.0 written on them should use pybv10_xxx.dfu files. A overview of changes for each version can be found here.
Suitable for PYBv1.0 boards:
Suitable for PYBv1.0 boards, with network drivers for CC3000 and WIZ820io included:

The following files are firmware for the WiPy. The zip file contains mcuimg.bin which should be copied via ftp to the /flash/sys directory on the WiPy.
The following files are stable firmware for the ESP8266. Program your board using the esptool.py program as described in the tutorial.
The following are daily builds of the ESP8266 firmware. They have the latest features and bug fixes, WebREPL is not automatically started, and debugging is enabled by default.
The following are daily builds of the ESP8266 firmware tailored for modules with only 512kbytes of flash. Certain features are disabled to get the firmware down to this size.
The following are Over-The-Air (OTA) builds of the ESP8266 firmware, for modules with at least 1MByte of flash. The first time you use this build you need to flash one of the "initial image" images using esptool.py as described above. After that, you can update the firmware over the air using the "OTA update" file in conjunction with the ota-client script from yaota8266. The "OTA update" files are digitally signed and will only work with the provided "initial image" files, and vice versa. (Note: this feature is work-in-progress.)
The following files are daily firmware for ESP32-based boards. Program your board using the esptool.py program, and put the firmware starting at address 0. If you are putting MicroPython on for the first time then you should first erase the entire flash.
These boards are not officially supported but should be fully functional:
