This release adds block and block editor support to the Raspberry Pi Pico (and other RP2040-based boards with compatible Quad SPI flash). Note that by default only 1 MB of block space is available, so if one is using boards other than the Raspberry Pi Pico source code changes will be needed to take advantage of a greater amount of Quad SPI flash space. Additionally, on the Raspberry Pi Pico duplicate constants in constant pools are now detected and eliminated, for greater code density.
