This replaces the :: and -> words with separators within words being looked up that differ from them because no spaces separate them and [ ... ] is not used in compilation state. Also, they can now be used with ', ['], postpone, averts, triggers, and like. Additionally, a major bug was fixed in object-orientation where it was effectively broken previously on the STM32L476.

This release adds optional support for bitmaps, I2C SSD1306-based displays, monospace bitmap fonts, and provides a simple ASCII monospace bitmap font; it also includes important bugfixes to the multitasker and to value and 2value.

This patch-level release extends support for lexically-scoped local variables to do loops and to case constructions, so local variables can safely be declared inside them and declared outside them and used within them.

This patch-level release adds lexical scoping within conditional/looping constructs to local variables declared with { ... }, except for in do-loops and case constructs, where local variables are not currently supported.

This release adds value, 2value, and local variables declared with { ... }, along with the words to and +to to set and add to them.

This patch-level release fixes an issue with create-file, write-file, write-file-window, and append-file in fat32-tools where they left unneeded data sizes written on the stack, and adds a new word copy-file to fat32-tools which enables copying of entire files arbitrarily.

This release adds a new fat32-tools module for accessing FAT32 filesystems on SDHC/SDXC cards in a user-friendly fashion, along with significant performance improvements to the multitasker enabled by rewriting code in the critical path in inline assembly.

This patch-level release adds the armv6m assembler to all builds and has the "minidictionary" code for the Raspberry Pi Pico rewritten in assembly to optimize its performance.

This patch-level release fixes multiple I2C-related issues, particularly with regard to STOP conditions.

This patch-level release fixes a major bug in the I2C layer for the Raspberry Pi Pico where I2C target addresses were not being set correctly.
