Release 0.9.16 - Factorization, precision fixes, and documentation This release adds prime and factorization features, improves numeric precision, and expands simulator and user documentation. New features ============ * Add `IsPrime`, `Factors`, `PrevPrime` and `NextPrime` commands * Add `MaxFactorsBits` and `MaxFactorIterations` settings for factorization * Add `TRIGSIN` command for Pythagorean identity rewrites * Add a Unix man page and simulator documentation * Add simulator recorder dump on `F16`; move demo playback to `F13`-`F15` * Paint navigation arrows in `SHOW` * Accept `CR/LF` line endings when reading Windows files * Display keyboard access paths in help for commands Bug fixes ========= * Fix `expm1` precision loss for small arguments, including complex values * Fix `ln1p` precision loss for small arguments * Fix shift behavior after transient alpha, and support shift/xshift for transalpha * Reset `show_x` and `show_y` when exiting `SHOW` * Ensure the simulator creates the `screens` directory when needed * Fix an infinity optimization regression in arithmetic * Add missing null-dereference checks in factorization code * Treat `^` as right-associative like on the HP50G Enhancements ============ * Refactor and optimize the decimal factorization code path, with expanded tests * Add conversion support to `float` and `double` in algebraic code * Update to recorder v1.2.3 * Add documentation updates (DeepWiki reference, legal notice updates) * Add build preparation for upcoming make-it-quick integration * Welcome several new authors to the team, see AUTHORS file * Add LEGAL-NOTICE.md about compliance with California and Colorado laws * Add menu entries for `hypot` and `atan2` Signed-off-by: Christophe de Dinechin <christophe@dinechin.org>
