Hi Marcus. Since there haven't been any updates here since end of April could we except one on current progress? I personally would be very grateful. I look forward to the release of mbed 5.9.

I'm also interested if there will be support for bootloader and ota dfu for nrf52832 target.

Any chance we can get dynamically configurable TWIS/TWIM support?
