This release replaces the old action scheduler, which while simple and lightweight was not very powerful, with a far more powerful action scheduler that enables actions, which are lightweight asynchronous activities that execute within a single task for a given schedule, to synchronously send messages to one another at a high messaging rate (one action continually sending messages to a receiving action will run at about 13 kHz on the Raspberry Pi Pico and 27 kHz on the STM32F746 DISCO).
