See #1662
There is also an optimisation : shuffle = pow(oeps, errs) + eps; outside a loop which does not change nor oeps nor errs. All solver 41 tests passes.

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

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

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
