FrugalEDA documentation ChangeLog

v0.3 – 10.09.2026

Documentation overhaul across the whole suite:

  • New JOINUS-D user manual and command-line reference. JOINUS-D is now presented as FrugalEDA's main application: draw a circuit in LibrePCB, convert it, simulate it, and analyse its operating margins, fabrication yield and optimization — all in one window.
  • L2SPICE quick guide and user manual rewritten for the new project-based workflow, with simulation results shown directly in the built-in FrugalPlot viewer.
  • New FrugalPlot manual — the interactive tool for viewing and comparing simulation and measurement curves.
  • Superconductor library reference guide brought up to date.
  • Home page and What is FrugalEDA? page rebuilt around the full set of tools.
  • Getting-started and installation pages refreshed.
