+La clé |right-overlap| est une clé booléenne dont la valeur initiale est |true|. Elle concerne uniquement les
+environnements |{WithArrows}|.

+Quand la clé |right-overlap| est active, les flèches (et leurs étiquettes) sont tracées en débordement et n'entrent

+
+Quand la clé |right-overlap| est mise à |false| (dans |\WithArrowsOptions| ou bien dans un environnement
+|{WithArrows}| individuel) le débord vers la droite est pris en compte dans le calcul des dimensions de la boîte
+englobante.

-% Arrows of type |o| which are \emph{over} other arrows.
+% \subsection*{Changes between versions 1.4 and 1.5}
+%
+% The Tikz code used to draw the arrows can be changed with the option
+% |tikz-code|.
%
-% \pkg{witharrows} now requires and loads \pkg{varwidth}
+% Two new options |code-before| and |code-after| have been added at the
+% environment level.
%
-% \subsection*{Changes between 2.5 and 2.5.1}
+% A special version of |\Arrow| is available in |code-after| in order to draw
+% arrows in nested environments.
%
-% Correction of the erroneous programmation of the nodes aliases.
+% A command |\MultiArrow| is available in |code-after| to draw arrows of other
+% shapes.
%
-% \subsection*{Changes between 2.5.1 and 2.6}
+% \subsection*{Changes between versions 1.3 and 1.4}
+%
+% The package \pkg{footnote} is no longer loaded by default. Instead, two
+% options |footnote| and |footnotehyper| have been added. In particular,
+% \pkg{witharrows} becomes compatible with \cls{beamer}.
%
-% The key |format| now supports the letters |R|, |C| and |L|.
+% \subsection*{Changes between versions 1.2 and 1.3}
%
+% New options |ygap| and |ystart| for fine tuning.
%
-% \subsection*{Changes between 2.6 and 2.6a (and 2.6b)}
+% \subsection*{Changes between versions 1.1 and 1.2}
%
-% Replacement of |\hbox_unpack_clear:N| by |\hbox_unpack_drop:N| since
-% |\hbox_unpack_clear:N| is now deprecated in \pkg{expl3}.
+% The package \pkg{witharrows} can now be loaded without having loaded
+% previously \pkg{tikz} and the libraries |arrow.meta| and |bending| (this
+% extension and these libraries are loaded silently by \pkg{witharrows}).
%
-% Version 2.6d: correction of a bug (cf. question 628461 on TeX StackExchange).
+% New option |groups| (with a \emph{s})
%
-% \subsection*{Changes between 2.6b and 2.7}
+% \subsection*{Changes between versions 1.0 and 1.1}
+%
+% Option for the command |\\| and option |interline|
+%
+% Compatibility with |\usetikzlibrary{babel}|
%
-% Correction of a bug: when the key |wrap-lines| was in force, the content of
-% the annotations was not ``flush left'' by default as it should be (but justified).
+% Possibility of nested environments |{WithArrows}|
