v3.0.0

3.0.0 (2026-08-14)

⚠ BREAKING CHANGES

• Helper.eqSet is now Helper.equationSet.
• database now holds 129 entries instead of 127; the two added are marked active: false. Consumers reading it directly must skip them.
• the package is ESM-only and has no default export; import the named exports instead.
• corrected constants change computed results — the phosphorous acid chain, Mn(OH)2, PbI2 and the six ethylenediamine complexes — and the solid convergence test is now relative, so hydroxide systems that used to return null converge.
• the package has no default export anymore. Use import { Equilibrium } from 'chem-equilibrium' instead of import Equilibrium from 'chem-equilibrium', and the UMD bundle exposes ChemEquilibrium.Equilibrium instead of ChemEquilibrium.default. The Equilibrium.Helper and Equilibrium.Serie static properties are gone, import Helper and Serie directly.

Features

• drop default exports in favour of named exports (5336223)
• make src/data the source of truth and record inactive entries (373c6dc)
• migrate package to ESM and current tooling (3d5d1ee)
• move to a monorepo with equilibrium.cheminfo.org (335dbda)
• name the site equilibrium.cheminfo.org and mark where curves bend (69bfd6a)
• rename Helper.eqSet to equationSet and document the optional types (5f99614)
• set the name as EquiLibrium and inline the EPFL logo (92f2ced)
• ship only the solver, and move the site to its own repository (7a154e8)

Bug Fixes

• build the library before linting (3ca1200)
• H2PO3 to H3PO3 (2ad1c5b)
• name ethylenediamine by its formula rather than en (ff8c88e)
