Release 0.9.19 "Spirit" - More constants, more space left

[c3d]

This release includes a larger-than-usual number of changes, mostly to make room for more constants. A side effect is that we gained a lot of
additional space for the DM42, giving us a lot of headroom for future developments. On the other hand, this may cause unexpected bugs. If
you run DB48x on a DM42, please check for anything out of the ordinary and report it.

New features

• Hierarchical constants library, with astronomy data for planets
• fonts: Add astronomy-related glyphs and a few more
• simulator: RPL evaluation with -e, to preload the calculator
• simulator: RPL console evaluation mode with -E (prints to console)
• simulator: RPL evaluation from file with -f and -F
• simulator: headless mode with -H (no window showing)
• simulator: screen capture with -C for scripting
• simulator: Persist window geometry across runs
• simulator: Persist calculator state on exit
• ui: Enhanced behaviour for EEX key (skips to exponent)
• variables: Store and recall to path
• GCD (GreatestCommonDenominator) and LCM (LeastCommonMultiple)
• Quote command
• Hitting EXIT while editing clears menu

Bug fixes

• variables: Memory corruption when replacing object with subobject
• Fix parsing bug causing partial load of .48k keymaps beyond @
• arrays: Strip tags from array and index in get and put
• solver: Improve solver precision in Std mode
• constants: Correcting the standard uncertainty of several constants.
• constants: Correct the Tau mass relative uncertainty.
• Make sure simulators get the correct help file (distinct .qrc files)
• Show empty menu when entering empty directory in 1-line mode
• Accept decimal / fraction conversions for arrays containing names
• Make it possible to reload Demo.48s after initial run on DM42
• Correctly show error message while loading files
• ui: Do not remove - when using CHS in an expression like 5-3.
• bignum: Remove leftover printf statement
• menu: Refresh CustomMenu if updated while active
• simulator: Fix race condition in Paste command
• ci: keep Android AABs under android/
• ci: package db50x Windows simulator from the correct path

• ci: use libsystre in Windows packaging
• doc: Fix description of simulator -m option
• ids: Fix aliases for EquationValue and XLibValue
• menus: Connect menu entries incorrectly marked as unimplemented
• Fix help topics for various constants / constant groups

Improvements

• fw: Move all C / C++ strings to the QSPI on DM42 (save >80K flash)
• tests: Replace LSHIFT, I with ID_ConstantsMenu for readability
• tests: Run cstlib / eqlib tests beyond first error
• tests: Use STD instead of 12 SIG
• tests: Do not save state file after running the test suite
• Do not waste memory while converting<<, >> and ->
• Improve rebuild in case of QSPI CRC mismatch
• Enable make TAR_EXTRA_FILES= install to install only binaries
• makefile: Generate listing files like the old makefiles
• makefile: Add image comparison targets like in old makefile
• makefile: Avoid extraneous / in paths
• makefile: Pass DB48X_VERSION through the command-line
• debug: Change debug_printf to use all 12 rows
• commands: micro-optimize factorization of cmp == 0 test
• chuck: Make the CHUCK command optional for repeatable builds
• install: Add DISK_NAME variables to specify volume name
• ui: Simplify display of alpha and user indicators
• doc: Add information on how to start Fedora on WSL
• ui: Fix misspelling in comment
• doc: Make the age-verification LEGAL-NOTICE more general
• chore(ci): bump packages versions

• version: Update copyright year to 2026
• parser: Accept , as a separator in algebraic function calls
• Reorder the constants menu for efficiency
