A new minor release, bringing support for Power Delivery 3.0 communication, programmable power supplies, requests from voltage ranges, new methods of specifying the required power level, and jumping to the STM32 DFU bootloader.
set_vrangecommand provides a fallback if the preferred voltage is unavailable.
set_p) or a resistance (
set_r), as well as a current. These values are taken as constant over the configured voltage range.
bootcommand causes the firmware to run the microcontroller’s built-in DfuSe bootloader.
For this release, the firmware was reorganized as a library for USB Power Delivery and an application using that library. The library is released under the Apache License, Version 2.0, and the application is still released under the GNU General Public License, Version 3.0. Both parts of the firmware are still kept in this repository, but this may change at some point.

A new minor release, bringing the ability to do Power Delivery communications in Sink mode. Two new commands were introduced to support this:
output: Enable or disable the power output, or read its current status.
get_source_cap: Print the advertised capabilities of the Power Delivery source.
To match the old behavior, the power output is disabled by default in Sink mode, and remains disabled unless explicitly enabled by the user. If the output is enabled, the configured power is negotiated immediately and made available on the output connector. Negotiation is then done every time new configuration is written to flash, so that new power can be acquired quickly and easily.
