This release adds support for double-cell and for address-type local variables.

This patch-level release adds convenience words for controlling the state and direction of pins from the pio module and also adds automatic relocation of PIO programs.

This patch-level release adds official support for the SeeedStudio XIAO RP2040, adds a Neopixel driver for the RP2040, adds the ability to turn off console colors, and fixes a stack garbage issue.

This patch-level release is a bug-fix release for bugs in the lock (with regard to priority inheritance handling), fat32 (with regard to date handling), and sd (with regard to error handling) modules. It also increases the local variable stack size to 512 bytes.

This patch-level release adds a simple-date-time! word to the rtc module for the RP2040 (i.e. the Raspberry Pi Pico) and increases the maximum size of the word search order to 32.

This patch-level release fixes a major bug in local variables in nested quotations, adds creation/modification date/time support (using the realtime clock on the Raspberry Pi Pico) to the FAT32 layer, adds minimal stubs for date/time handling to platforms without full RTC support, adds day-of-the-week calculation, and adds date display in fat32-tools::list-dir.

This release adds the rtc module for the RP2040 (i.e. the Raspberry Pi Pico), which provides support for the RP2040's realtime clock (RTC).

This release adds the timer module for the RP2040 (i.e. the Raspberry Pi Pico) which adds support for the hardware timer and alarms.

This release adds a pwm module for the RP2040 (i.e. the Raspberry Pi Pico) which exposes both PWM output and PWM input to the user.

This patch-level release fixes some issues with the GPIO layer implementation on the RP2040 and expands support for GPIO interrupts to the second core. It also contains example code for using GPIO interrupts on the RP2040 to read temperatures from an LMT01 temperature sensor.
