(backported to 2.2.4).
- FIX: Fixed timeout problem in the lwIP interface layer (bug 3302420)
(backported to 2.2.4).
- NEW: Added a chprintf() function to ./os/various, it can print on any
BaseChannel.
- NEW: Improved the mini shell, enhanced info command, optimizations and
removed the shellPrint() and shellPrintLine() functions, now it uses
chprintf() for output.
- NEW: lwIP 1.4.0 has been integrated, this new version does not require
custom hooks into the Thread structure and is thus much lighter.
- NEW: FatFs demo for the STM32F103ZG using the SDC driver.
