Marlin 2.0.8.2

Marlin 2.0.8.2 is a maintenance release with a number of small improvements and issues fixed.

This release adds cap:HOST_ACTION_COMMANDS:0/1 to the M115 extended capabilities report so hosts like OctoPrint can check for basic host-firmware interaction with //action: commands. For more complete interactivity you should enable HOST_PROMPT_SUPPORT and this will report cap:PROMPT_SUPPORT:1 to the host.

Marlin 2.0.6

For this release we focused on compatibility with a wider range of boards and controllers, especially STM32-based boards, color screens, and touch screens. With so many new files being added, a lot of work has gone into optimizing the PlatformIO build by peeking at enabled features and only downloading libraries and compiling code required for your enabled options. And we tackled a whole host of issues from stepper timing and interrupt priority down to the details of controller-wheel responsiveness.
