Announcement text: -------------------------------------------------------------------------------- [2026/11/03 — version 1.01c] Added

\tkzFnImplicit[options]{F(x,y)}: curves defined implicitly by F(x,y) = 0, written as an expression or as an equation ({x^2 + y^2 = 4}). Marching squares on a grid of the window, crossings computed by bisection, false crossings at discontinuities removed, double points handled. Options level (level curves F(x,y) = c, list accepted), samples, domain, ydomain, refine, clip. Documentation: new section "Implicit curves" / "Courbes définies implicitement" in both languages. --------------------------------------------------------------------------------
