## [2.20c] — 2026/10/20 ### Changed - Keys use `pgfkeys` instead of `xkeyval`: same names, same default values, same results. The behaviour of `\presetkeys` is kept (preset values apply only to the keys not given; `\SetVertexMath`, `\SetUpEdge`, `\GraphInit`... still change them). - `xkeyval` is no longer loaded: a document that used it without loading it must now load it. - `vstyle` and the `dir` key of `\grLoop` accept a macro as value. - The short names (`\Vertex`, `\Vertices`, `\Edge`, `\Edges`, `\Loop`, `\EA`, `\WE`, `\NO`, `\SO`, `\NOEA`, `\NOWE`, `\SOEA`, `\SOWE`) are installed at the beginning of each `tikzpicture`. A definition of `\EA`, `\NO`... made elsewhere (by the user or another package) keeps its meaning outside the pictures. If such a name is already defined when tkz-graph is loaded, a warning gives the prefixed name. - The code calls only internal commands (`\tkzgr@...`); tkz-berge does the same. - Each `vstyle` is a pgfkeys key (`/tkzgraph/vstyle/<name>`). - Internal macros protected; `\ifthenelse` no longer used internally (`ifthen` is still loaded); `etex` removed; `\fileversion` and `\filedate` are no longer redefined. ### Fixed - `\AddVertexColor` and `\Vertices` no longer depend on global helper macros (`\deb`, `\fin`, `\v`, `\liste`...). - A second `\GraphInit[vstyle=...]` in the same group was ignored and wrote its value in the text (the internal macro `\GR@init@vstyle` overwrote the key itself). ### Added - Prefixed names, always available: `\tkzVertex`, `\tkzVertices`, `\tkzEdge`, `\tkzEdges`, `\tkzLoop`, `\tkzEA`, `\tkzWE`, `\tkzNO`, `\tkzSO`, `\tkzNOEA`, `\tkzNOWE`, `\tkzSOEA`, `\tkzSOWE`. - Package option `noshortnames`: the short names are never defined. - `\tkzDefGraphStyle{<name>}{<code>}` defines a new style for `\GraphInit[vstyle=<name>]` (name case insensitive). - `\tkzSetUpGraph[...]`: local settings of the vertices, edges and labels (`vertex shape`, `vertex line width`, `vertex line color`, `vertex text color`, `vertex fill`, `light fill`, `dark fill`, `ball color`, `inner sep`, `outer sep`, `small size`, `medium size`, `big size`, `edge color`, `edge width`, `edge fill`, `art color`, `double distance`, `label text`, `label fill`, `unit`), `directed` (an arrow on every edge) and `arrow tip`. It replaces the `\renewcommand` of `\VertexShape`, `\EdgeLineWidth`... - Keys `->`, `<-`, `<->`, `-` and `arrow` for `\Edge` and `\Edges`. - Keys `rotation` (angle of the first vertex) and `clockwise` for `\Vertices{circle}`. - `\tkzHighlightPath[options]{A,B,C}` (path, option `cycle`) and `\tkzHighlightPath{A/B,C/D}` (edges): edges drawn again over the graph (`color`, `lw`, `style`). - `\tkzAdjacencyMatrix[options]`: adjacency matrix of the graph of the last picture (options `directed`, `order`). - `\tkzGraphFromMatrix[options]{A,B,C}{0,1,1;1,0,1;1,1,0}`: graph (vertices on a circle, or `placed`) from a matrix; options `directed`, `weighted`, `unit`, `rotation`, `clockwise`, `style`, `loop distance`, `bend`. - `\grProbMatrix{A,B,C}{matrix}`: probabilistic graph with any number of states, from the transition matrix. ### Compatibility - Same rendering for the existing documents. `arrows.meta` is not loaded (it changes slightly the default tip); load it to use `arrow tip=Stealth`. - tkz-berge must be 2.20c or later (older versions need `xkeyval`).
