Alain Matthes submitted an update to the

tkz-elements

package.

Version: 4.20c 2025-09-17 License: lppl1.3c

Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide

Announcement text: ----------------------------------------------------------------------

New triangle methods: thebault/c_c (Thébault’s problem III), mixtilinear_incircle, three_tangent_circles, morley, soddy, napoleon, poncelet_point, orthopole; plus orthopole support for quadrilaterals via helper tkz.orthopole(a,b,c,l).

Improvements: circle (common_tangent, orthogonal_through, orthogonal_from, c_cc_p), line (distance), and rewritten triangle methods (symmedian_line, altitude, bisector, bisector_ext, mediator, ex_circle, reflection).

Docs: new Best practices subsection, additional examples (Thébault III, Poncelet point for triangle/quadrilateral, orthopole), and assorted fixes. Backward compatible.

GitHub introduction Source, roadmap, issues and the full CHANGELOG live on GitHub: https://github.com/al-ma-dev/tkz-elements. Feedback and contributions are welcome (see CONTRIBUTING.md). The PDF manual ships in the repo and on CTAN.
