Summary description: A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
Announcement text:
Added - path Method 'scale' Anisotropic scaling - fct Added half_tangents and tangent methods. Tangents now return unit direction points (no line objects). Fully compatible with set_scale. Unified implementation based on drawing coordinates. Changed - path homothety now center is optional - fct et pfct Removed graph-related drawing macros (\tkzDrawPointOnGraph, \tkzDrawPointsOnGraph, \tkzDrawPointOnParamGraph, \tkzDrawPointsOnParamGraph). These were incompatible with set_scale and contradicted the Lua-computation / TikZ-drawing design principle. - tkz-elements.sty Deletions and corrections.

tkz-elements – A Lua library for drawing Euclidean geometry with TikZ or tkz-euclide
This package provides a library written in Lua, allowing to make all the necessary calculations to define the objects of a Euclidean geometry figure. You need to compile with LuaLaTeX. The definitions and calculations are only done with Lua.
The main possibility of programming proposed is oriented “object programming” with object classes like point, line, triangle, circle and now, conic. For the moment, once the calculations are done, it is tkz-euclide or TikZ which allows the drawings.
