This patch-level release expands the set of compat words, in particular adding new string-related words, adds exclusive-or load-modify-store words, and changes the hash algorithm used for the dictionary index on the rp2040 and rp2040_big platforms to be a slightly modified (to take into account wordlist IDs and to be case-insensitive) Fowler-Noll-Vo hash function for better distribution of words in the dictionary index.

This patch-level release adds a variety of compatibility words (i.e. words from ANS Forth or Forth 2012) to the compat module.

This bug-fix release fixes an issue with 2lshift, 2rshift, and 2arshift where they may cause sporadic erroneous results on the STM32F746.

This minor release adds a compat module which contains a number of words for compatibility with ANS Forth / Forth 2012, and fixes the handling of delimiters after tokens (i.e. always skipping past the initial delimiter rather than requiring other words such as s" to manually do this); this was needed because of the behavior of word and parse in the compat module.

This patch-level release fixes an issue with the multitasker where if all tasks on one core were blocking, they would prevent any pending operations on that core from executing repeatedly. This caused issues with the USB CDC console in multicore code.

This patch-level release fixes an issue with interrupt::NVIC_IPR_IP! and interrupt::NVIC_IPR_IP@ which rendered them non-functional at least on the RP2040.

This patch-level release fixes an issue with UART1 on the RP2040 when multicore code is running. It also expands buffer sizes for UART's on the RP2040 from 128 to 256 bytes.

This minor-level release fixes issues with wait-notify, wait-notify-indefinite, and wait-notify-timeout in the task module which had rendered them unusable and also removes "critical" multitasking constructs because they do not do what they were created for (e.g. there is no actual guarantee that other code will not execute between the time when they could first wake and when the tasks in question actually resumed execution.

This patch-level release contains all the recent fixes (e.g. the RP2040 division/modulus fix) and also contains an important fix to see etc. where it had been breaking if instructions such as LDRH or STRH were disassembled.

This patch-level release is for all platforms and fixes a number of long-standing bugs, mostly concerning multitasking. It is compatible with zeptoIP and the CYW43439 driver, which are in the devel branch.
