This patch-level release fixes a couple significant bugs in the multitasker and peripheral support for the Raspberry Pi Pico with regard to multicore operation; booting the second core was incorrectly resetting systick-counter to 0, which was causing problems with other tasks, particularly tasks in the midst of a delay, and interrupts were not being properly initialized when the second core was being booted, which was causing problems with regard to the I2C peripherals of the RP2040 in particular. Also note that interrupts are now being used by the SPI peripherals of the RP2040, whereas previously interrupts had not been properly initialized for such.
