Thank you for using Formulary+!

### 2.1.0 — 2026-05-30

bug fixes

### 2.0.0 — 2026-05-19

• Library expanded to 3,899 formulas across 16 disciplines and 150 subcategories — Mathematics, Physics, Chemistry, Geometry, Environmental, Geological, Chemical, Mechanical, Electrical, Civil, Geophysics, Geochemistry, Biology & Biomedical, Computer Science, Meteorology & Atmospheric, Astronomy & Astrophysics.
• Render fixes: corrected placeholder LaTeX in 5 formulas so equations now display properly instead of raw text.
• Variable list cleanup: 24 Geometry formulas had unrelated physics variables (capacitance, magnetic field, etc.) replaced with the correct geometric quantities.
• Description rewrites: 105 truncated formula descriptions across 14 disciplines were finished so every formula now reads as a complete sentence.
• Seed/upsert engine: fresh installs now correctly link every formula to its subcategory, so every category shows its full formula set on first launch.
• Versioned data store: the bundled formula set is gated by a data-version key, so upgrades automatically pull in corrected definitions without you needing to reinstall.

Thanks for using Formulary+! If you spot anything that should be corrected, please reach out via the Support URL.
