zeptoforth

This bug-fix release resolves another issue with constant pools (when used with code[) and fixes an issue with the CYW43439 driver where it at times overflows its dictionary space (e.g. while running test/rp2040/pico_w_net_http_download.fs).

This bug-fix release fixes a critical issue with zeptoforth on the RP2040, which amongst other things breaks zeptoIP (how it even works at all is questionable). It is highly recommended one upgrade to this release immediately if one is using the RP2040.

This patch-level release adds initializer to add convenient initializers that work both when compiling to RAM and when compiling to flash, and optimizes literal pools on the RP2040.

This patch-level release added task::with-timeout and task::with-timeout-from-start as convenience words for temporarily setting task::timeout in a set scope, whether directly or from a start time. Also, zeptoIP has been modified to use these words and have proper support for setting, via the constant max-endpoint-in-size, the input buffer size for endpoints, which has also been increased from 1500 to 3000 bytes.

This bug-fix release fixes an issue with f** that was causing the inappropriate raising of x-domain-error when the exponent was 0,0 (when this should only happen with 0,0 0,0 f**). Also, it adds net::wait-ready-endpoint to zeptoIP for doing a blocking wait on an endpoint's becoming ready.

This release is the official introduction of zeptoIP, zeptoforth's IPv4 stack for the Raspberry Pi Pico W. Note that it is not included in any official binaries due to intellectual property reasons (specifically the non-free-ness of the CYW43439 firmware needed for the Raspberry Pi Pico W), but BUILDING_AND_USING_ZEPTOIP.md includes directions for building zeptoIP and its associated CYW43439 driver. The firmware is mirrored here.

This patch-level release fixes task::dump-tasks, 2arshift, and the font in extra/common/simple_font.fs, removes unnecessary code from the RP2040 division/modulus routines, adds fmod, and removes task::trace and associated words.

This bug-fix release fixes an issue with non-power cycle hardware resets on RP2040 boards which support them (such as the SeeedStudio XIAO RP2040 and the Cytron Maker Nano RP2040) which had previously been causing flash to be erroneously reported as being full. It also fixes an issue where the flash erase marker was in the wrong location on rp2040-big configurations. Note that no changes have been made in non-RP2040 binaries aside from changing their filenames ─ they will still report their version as being 1.2.3.1.

This bug-fix release fixes a bug in block storage in rp2040_big configurations caused by an unchanged block storage address relative to rp2040 and a bug in the block editor that manifested itself when using the USB CDC console due to attempting to interface with the terminal inside critical sections, which is verboten when using the USB CDC console.

This patch-level release improves the performance of spi::buffer>spi and spi::spi>buffer, adds support for underscores in numbers such as 1_000_000, adds page for clearing the console, and fixes a bug in the handling of long lines by the USB CDC console which had been causing dropped bytes.
