June 2026

6/12/2026: Rolling out to Experimental, Experimental (26H1), and Experimental (Future Platforms) with version 11.2605.9.0

  • More accurate square-root results — Fixed rare cases where a calculation that should equal zero (like sqrt(2.25) - 1.5) returned a tiny leftover value instead.
  • Readable text in High Contrast themes — Settings text now shows the correct colors in the High Contrast Aquatic and Desert themes.
  • Fixed layout for right-to-left languages — For languages like Arabic and Hebrew, the graph, number pad, equation fields, and scroll buttons now appear correctly oriented.
  • Reliable launch after upgrading — Fixed an issue where upgrading from much older versions could leave outdated settings that stopped the app from opening.
