% Changes in 1.46c (2026/10/20) -- same text as 1.45c, but the index changes:
%  - identification part placed first (\NeedsTeXFormat, \ProvidesClass);
%  - NewMacroBox / NewEnvBox no longer write a spurious index entry
%    (the whole "name + arguments" string was indexed in addition to the
%    correct \Imacro / \Ienv entry);
%  - \presentation can be used more than once (\newlength moved outside);
%  - \tkzNameMacro and \TMline no longer index their argument twice;
%  - \tkzTitleFrame: \protected@edef instead of \edef (fragile commands
%    in the title no longer break); with the option cadre, pgfornament is
%    loaded automatically if the document does not load it;
%  - \tikzstyle (deprecated) replaced by \tikzset;
%  - duplicate definitions of \TeX, \LaTeX, \LATEX removed; \TeX robust;
%  - fallback colours and default values for the \tkz...ofpack macros
%    when tkz-doc.cfg or a definition is missing;
%  - \l@nohyphenation has a fallback if undefined;
%  - KOMA internal \idx@heading is redefined only if it exists;
%  - the e-mail address used by \presentation is \tkzmailofauthor;
%  - \TeX is robust again (as in the kernel): an index entry containing
%    \TeX (e.g. \tkzNamePack{Lua\TeX}) is sorted differently;
%  - \tkzSetUpColors no longer adds spurious spaces;
%  - option cadre: only a warning if pgfornament.sty is not installed;
%  - no \url / \href defined by the class: the cover and \presentation
%    use them only if they exist (hyperref, url).
