\part{Introduction}
\section{New in v1.5}
+\subsection{The primitive \texttt{\protect\textbackslash expanded}}
+As of version 1.54, \CF requires a \TeX{} engine that provides the \verb|\expanded| primitive. If this is not available, \CF will not be loaded. It is strongly recommended that you update your \LaTeX{} distribution in order to take advantage of the newer engine that provide for the use of this new primitive.
+
\subsection{The macro \texttt{\protect\textbackslash charge}}
Version 1.5 implements the macros \verb|\charge| and \verb|\Charge| (see page~\pageref{charge}) whose purpose is to place arbitrary elements around an atom that can be placed with great precision. These macros will replace the \verb|\lewis| and \verb|\Lewis| macros because they are much more powerful and configurable, even if more verbose. It is therefore important to note that the macros \verb|\lewis| and \verb|\Lewis| \textcolor{red}{\bfseries are no longer documented and will be removed from the \CF package}.

\part{Introduction}
\section{Nouveau dans la v1.5}
+\subsection{Primitive \texttt{\protect\textbackslash expanded}}
+À partir de la version 1.54, \CF nécessite un moteur \TeX{} fournissant la primitive \texttt{\string\expanded}. Si ce n'est pas le cas, le package \CF ne sera pas chargé : il est donc vivement conseillé de mettre à jour sa distribution \LaTeX{} afin de profiter d'un moteur récent permettant l'utilisation de cette nouvelle primitive.
+
\subsection{La macro \texttt{\protect\textbackslash charge}}
La version 1.5 met en place les macros \verb|\charge| et \verb|\Charge| (voir page~\pageref{charge}) dont le but est de placer atour d'un atome des éléments arbitraires avec une grande précision. Ces macros remplaceront, à terme, les macros \verb|\lewis| et \verb|\Lewis| car elles sont bien plus puissantes et configurables, même si plus verbeuses quant à leur emploi. Il est donc important de noter que les macros \verb|\lewis| et \verb|\Lewis| \textcolor{red}{\bfseries ne sont plus documentées et seront supprimées de l'extension \CF}.

-
-v0.1 2010/06/23
- - Premi\xE8re version publique sur le CTAN
-----------------------------------------------------------------------
-v0.2 2010/08/31
- - Ajout de la documentation en anglais.
- - Correction de bugs.
- - \printatom est d\xE9sormais une macro publique.
- - Les espaces sont permis dans les mol\xE9cules. Ils seront
- ignor\xE9s par d\xE9faut puisque les atomes sont compos\xE9s en
- mode math par \printatom
- - Une paire de Lewis peut \xEAtre repr\xE9sent\xE9e ":".
- - Dans les cycles, une correction de la longueur du trait
- d\xE9port\xE9 des liaisons doubles est fait de telle sorte que si
- l'on \xE9crit \chemfig{*5(=====)}, on obtient deux polygones
- r\xE9guliers concentriques.
- - La s\xE9quence de contr\xF4le \setnodestyle permet de sp\xE9cifier
- le style des n?uds dessin\xE9s par tikz.
-----------------------------------------------------------------------
-v0.3 2010/11/21
- - Am\xE9lioration de \definesubmol qui accepte les s\xE9quences de
- contr\xF4le. On peut aussi choisir un alias dont la substitution
- est diff\xE9rente selon l'orientation de la liaison qui lui
- arrive dessus.
- - Le caract\xE8re "|" force la fin d'un atome. Si on \xE9crit
- "D|ef" alors, chemfig verra deux atomes "D" et "ef".
- - Le caract\xE8re "#" est reconnu lorsqu'il suit un caract\xE8re de
- liaison. Il doit \xEAtre suivi d'un argument entre parenth\xE8ses
- qui contient l'offset de d\xE9but et de fin qui s'appliqueront
- \xE0 cette liaison.
- - La macro \chemfig admet un argument optionnel qui sera pass\xE9
- \xE0 l'environnement tikzpicture dans lequel elle est dessin\xE9e
- - Mise en place de la repr\xE9sentation des m\xE9canismes
- r\xE9actionnels avec la syntaxe "@{<nom>}" devant un atome o\xF9
- "@{<nom>,<coeff>}" au tout d\xE9but de l'argument d'une liaison.
- Cette syntaxe permet de placer un n?ud (au sens de tikz) qui
- deviendra l'extr\xE9mit\xE9 des fl\xE8ches des m\xE9canismes.
- Le trac\xE9 des fl\xE8ches est faite par la macro \chemmove dont
- l'argument optionnel devient celui de l'environnement
- tikzpicture dans lequel sont faites les fl\xE8ches.
- - Pour le m\xE9canisme d'alignement vertical via le \vphantom, la
- commande \chemskipalign permet d'ignorer le groupe d'atomes
- dans lequel elle est \xE9crite.
- - La commande \chemname permet d'afficher un nom sous une
- mol\xE9cule. la commande \chemnameinit initialise la plus grande
- profondeur rencontr\xE9e.
- - La commande \lewis a \xE9t\xE9 modifi\xE9e de telle sorte que les
- dessins des d\xE9corations soient proportionnels \xE0 la taille
- de la police.
-----------------------------------------------------------------------
-v0.3a 2011/01/08
- - Correction d'un bug dans l'argument optionnel de \definesubmol
- lorsque celui-ci comporte des crochets.
- - Mise \xE0 jour du manuel en anglais.
- - Ajout de \vflipnext et \hflipnext pour retourner
- horizontalement ou verticalement la prochaine mol\xE9cule.
-----------------------------------------------------------------------
-v0.4 2011/03/07
- - chemfig est d\xE9sormais \xE9crit en plain-etex et donc
- utilisable par d'autres formats que LaTeX.
- - Un peu plus de rigueur avec les catcodes des caract\xE8res
- sp\xE9ciaux, notamment lorsque la commande \chemfig se trouve
- dans l'argument de \chemmove, \chemabove, \chembelow, \chemrel.
- TODO : faut-il \scantoker l'argument de \chemfig pour \xEAtre
- d\xE9finitivement d\xE9barrass\xE9 de ces histoires de catcode ???
- - Correction d'un bug dans le calcul de l'angle des liaisons
-----------------------------------------------------------------------
-v0.4a 2011/04/10
- - Correction d'un bug concernant l'argument optionnel en d\xE9but
- de mol\xE9cule.
-----------------------------------------------------------------------
-v0.4b 2011/04/24
- - l'argument de \chemfig est tok\xE9nis\xE9 avec \scantokens ce qui
- rend caduc tout souci de code de cat\xE9gorie, \xE0 part #.
- - la commande \setbondstyle permet de d\xE9finir le style des
- liaisons.
- - correction de l'affichage incorrect des doubles liaisons dans
- les cycles apr\xE8s les commandes \hflipnext et \vflipnext
- - correction d'un bug lorsqu'un alias commence une mol\xE9cule
-----------------------------------------------------------------------
-v1.0 2011/06/15
- - les sch\xE9mas r\xE9actionnels sont d\xE9sormais disponibles.
- - \Chemabove et \Chembelow modifient la boite englobante.
- - \Lewis modifie la boite englobante
- - les macros \chemleft, \chemright, \chemup et \chemdown
- affichent des d\xE9limiteurs extensibles \xE0 gauche, \xE0 droite,
- au dessus et au dessous d'un mat\xE9riel.
-----------------------------------------------------------------------
-v1.0a 2011/09/18
- - les macros \Lewis et \lewis admettent un argument optionnel
- - la macro \setlewisdist r\xE8gle la distance entre les 2
- \xE9lectrons
-----------------------------------------------------------------------
-v1.0b 2011/11/29
- - la commande \merge est d\xE9sormais prot\xE9g\xE9e entre
- \schemestart et \schemestop contre des d\xE9finitions par d'autres
- packages.
- - \box0 est utilis\xE9 au lieu du maladroit \unhbox0
-----------------------------------------------------------------------
-v1.0c 2011/11/30
- - la macro \+ n'est plus explicitement \xE9crite
- - v\xE9rifie que eTeX est le moteur utilis\xE9
-----------------------------------------------------------------------
-v1.0d 2011/12/19
- - les cercles des cycles \xE9taient trac\xE9s au mauvais moment. La
- longueur de la liaison qui les pr\xE9c\xE9dait influait sur le
- rayon du cercle : \chemfig{-[,0.5]**6(------)} donnait un bug
- \xE0 l'affichage.
-----------------------------------------------------------------------
-v1.0e 2012/01/13
- - la gestion des espaces dans les groupes d'atomes est
- d\xE9sormais plus rigoureuse. Plusieurs bugs ont \xE9t\xE9
- corrig\xE9
-----------------------------------------------------------------------
-v1.0f 2012/02/24
- - correction d'un bug avec \definesubmol, les catcodes n'\xE9taient
- pas correctement g\xE9r\xE9s.
-----------------------------------------------------------------------
-v1.0g 2012/11/16
- - correction d'un bug dans \CF_directarrow pour faire prendre en
- compte le style des fl\xE8che par d\xE9faut
- - correction d'un bug dans \CF_lewisc : la boite *doit* \xEAtre
- compos\xE9e en dehors de l'environnement tikzpicture pour
- \xE9viter nullfont si jamais \printatom ne passe pas en mode
- math.
- - correction d'un bug dans \CF_chemfigc : si une longueur par
- d\xE9faut est modifi\xE9e par [,<l>] au d\xE9but d'une mol\xE9cule
- et si des cycles \xE9taient emboit\xE9s, cette longueur n'\xE9tait
- pas appliqu\xE9e aux sous-cycles.
- - r\xE9-\xE9criture des macros \chemabove et \chembemow pour
- prendre en compte le bug (d\xE9sormais corrig\xE9) dans luatex.
- - nouvelle macro \setstacksep qui d\xE9finit l'espacement par
- d\xE9faut dans les macros \chemabove et \chembelow.
-----------------------------------------------------------------------
-v1.0h 2013/11/28
- - \chemname admet maintenant une version \xE9toil\xE9 qui ne tient
- pas compte des profondeurs pr\xE9c\xE9dentes.
- - \CF_dpmax est g\xE9r\xE9 globalement.
- - correction d'un bug dans "-U>" : le style de la fl\xE8che
- n'\xE9tait pris en compte pour l'arc.
- - correction d'un bug dans \CF_directarrow : l'angle de la
- fl\xE8che n'\xE9tait pas calcul\xE9
-----------------------------------------------------------------------
-v1.1 2015/02/13
- - correction d'un bug dans \CF_seeksubmol : la macro
- \CF_molecule est d\xE9pouill\xE9 de son \xE9ventuel espace
- en premi\xE8re position.
- - correction d'un bug dans \CF_arrowf : le nom du prochain
- n?ud courant "end at arrow@i" \xE9tait erron\xE9 dans le cas o\xF9 une
- fl\xE8che contenait un sous sch\xE9ma. Ce nom doit d\xE9pendre de
- \CF_schemenest.
- - la jonction entre deux liaisons cons\xE9cutives dans l'axe peut
- \xEAtre activ\xE9 avec \enablebondjoin et d\xE9sactiv\xE9 avec
- \disablebondjoin (pr\xE9f\xE9rable, \xE9tat par d\xE9faut).
- - \chemfig suivi d'une "*" demande \xE0 ce que les liaisons aient
- une longueur invariable : la distance inter-atome devient donc
- variable. Cette fonctionnalit\xE9 est d\xE9sactiv\xE9 dans les
- cycles afin que les polygones soient r\xE9guliers.
- \enablefixedbondlength permet cette fonctionnalit\xE9 pour
- toutes les macros \chemfig (m\xEAme non \xE9toil\xE9e) tandis que
- \disablefixedbondlength le d\xE9sactive.
-----------------------------------------------------------------------
-v1.1a 2015/02/23
- - correction d'un bug dans \CF_grabbondoffset. Si \chemfig est
- dans l'argument d'une macro, les # sont doubl\xE9s par l'action
- de \scantokens de la macro \CF_chemfigb et il faut un
- argument d\xE9limit\xE9 avant "(" pour absorber tous les #.
-----------------------------------------------------------------------
-v1.2 2015/10/08
- - correction d'un bug dans le trac\xE9 des liaisons de Cram.
- - cr\xE9ation de \setangleincrement.
- - chargement de "arrows.meta" et d\xE9finition de la fl\xE8che "CF"
- bas\xE9e sur "Stealth" et d\xE9finie avec \pgfdeclarearrow.
- Les anciennes fl\xE8ches "CF_full" et "CF_half" sont
- abandonn\xE9es puisque d\xE9finies avec \pgfarrowsdeclare.
- - fl\xE8che "-U>" corrig\xE9e : le placement des labels est
- maintenant correct dans tous les cas. Ainsi :
- -U>[<a>][<b>][<d>][r][a]
- place le label <a> pr\xE8s du d\xE9but de la fl\xE8che, quels que
- soient les signes du rayon r et de l'angle a.
- - \chemrel, \setchemrel et \chemsign sont supprim\xE9es.
- - compatibilit\xE9, avec les limitations d'usage, avec la
- librairie "externalize" : le \begin{tikzpicture} voit
- d\xE9sormais le \end{tikzpicture} correspondant dans la macro
- \CF_chemfigb.
-----------------------------------------------------------------------
-v1.2a 2015/10/21
- - erreur de copier-coller dans le code: une adresse url \xE9tait
- malencontreusement pr\xE9sente en plein milieu d'une ligne de
- code
-----------------------------------------------------------------------
-v1.2b 2015/11/15
- - bug dans \CF_seeksubmol qui laissait "*" dans le flux de
- lecture de TeX. Un message d'erreur est \xE9galement ajout\xE9
- en cas de "!" en fin de traitement.
- - correction d'un bug dans \CF_setbondangle o\xF9 l'angle [<:a>]
- n'\xE9tait pas \xE9valu\xE9 par \pgfmathsetmacro.
-----------------------------------------------------------------------
-v1.2c 2015/11/20
- - Correction d'un bug dans \CF_setbondangle : l'angle renvoy\xE9
- pouvait \xEAtre n\xE9gatif
- - Correction d'un bug dans \CF_directarrow : la macro \CF_ifempty
- n'est pas correctement d\xE9velopp\xE9e dans l'argument de
- \pgfpointanchor
-----------------------------------------------------------------------
-v1.2d 2015/12/01
- - correction d'un bug dans la fl\xE8che "-U"
- - la version \xE9toil\xE9e de \setcrambond dessine les liaisons de
- Cram en pointill\xE9s sous forme de trait large et non pas sous
- forme de triangle.
-----------------------------------------------------------------------
-v1.2e 2017/05/20
- - la macro contenant la d\xE9finition d'une fl\xE8che est
- d\xE9sormais "\CF_arrow(<nom>)", ainsi la macro \0 n'est plus
- d\xE9finie par \definearrow
- - remerciements rajout\xE9s apr\xE8s une suppression indue, pour ne
- froisser aucune susceptibilit\xE9
-----------------------------------------------------------------------
-v1.3 2018/03/08
- - tous les param\xE8tres sont d\xE9sormais pass\xE9s via \setchemfig qui
- fait appel \xE0 "simplekv". Par cons\xE9quent, _toutes_ les macros qui
- r\xE9glaient des param\xE8tres deviennent obsol\xE8tes, \xE0 savoir :
- \setcrambond, \setatomsep, \setbondoffset, \setdoublesep,
- \setangleincrement, \enablefixedbondlength,
- \disablefixedbondlength, \setnodestyle, \setbondstyle,
- \setlewis, \setlewisdist, \setstacksep, \setcompoundstyle,
- \setarrowdefault, \setandsign, \setarrowoffset,
- \setcompoundsep, \setarrowlabelsep, \enablebondjoin,
- \disablebondjoin et \schemedebug.
- et ces macros seront *supprim\xE9es* dans une future version.
- - la version \xE9toil\xE9e "\chemfig*" et les deux arguments optionnels
- de la macro "\chemfig[][]" sont \xE9galement optionnels et seront
- *supprim\xE9*s dans une future version afin d'acc\xE9der \xE0 la syntaxe
- \chemfig[cl\xE9s=valeurs]{code}
- - 6 nouveaux param\xE8tres : "lewis radius", "arrow double sep",
- "arrow double coeff", "arrow double harpoon", "cycle radius
- coeff", "arrow head".
- - correction d'un bug dans \CF_parsemergeopt qui dans certains
- cas, envoyait vers l'affichage des caract\xE8res
- - petit toilettage du code
- - macro \polymerdelim (non document\xE9e) exp\xE9rimentale et encore
- en phase de tests
- - suppression d'un registre d'\xE9criture de fichier
-----------------------------------------------------------------------
-v1.31 2018/04/05
- - correction d'un espace ind\xE9sirable dans \CF_ifnextchar
-----------------------------------------------------------------------
-v1.32 2018/08/23
- - d\xE9finition de \printatom, \CF_begintikzpicture et
- \CF_endtikzpicture dans le fichier t-chemfig.tex
-----------------------------------------------------------------------
-v1.33 2018/10/31
- - les macros d\xE9finies par \definesubmol peuvent d\xE9sormais avoir un ou
- plusieurs arguments
- - macro \polymerdelim document\xE9e
-----------------------------------------------------------------------
-v1.34 2019/02/23
- - bug dans la fl\xE8che "<->" corrig\xE9
-----------------------------------------------------------------------
-v1.4 2019/04/18
- - corrections de nombreux bugs
- - caract\xE8re priv\xE9 "_" et non plus "@" -> modifications \xE0 pr\xE9voir
- notamment dans la doc avec les codes sp\xE9cifiques aux fl\xE8ches, \xE7a
- risque de couiner sur tex.stackexchange.com
- - anciennes macros abandonn\xE9es et d\xE9sormais ind\xE9finies :
- \setcrambond, \setatomsep, \setbondoffset, \setdoublesep,
- \setangleincrement, \enablefixedbondlength,
- \disablefixedbondlength, \setnodestyle, \setbondstyle,
- \setlewis, \setlewisdist, \setstacksep, \setcompoundstyle,
- \setarrowdefault, \setandsign, \setarrowoffset,
- \setcompoundsep, \setarrowlabelsep, \enablebondjoin,
- \disablebondjoin et \schemedebug
- - l'ancienne syntaxe \chemfig[][]{} est abandonn\xE9e et n'est plus
- accept\xE9e, d\xE9sormais c'est
- \chemfig[<cl\xE9s>=<valeurs>]{<code mol\xE9cule>}
- - l'ancienne syntaxe \lewis[<coeff>] ou \Lewis[<coeff>] n'est
- plus accept\xE9e au profit de \lewis[<cl\xE9s>=<valeurs>]
