+
+v1.0 19/8/2016
+ - Première version publique
+
+v1.1 01/09/2016
+ - Stockage des séparateurs dans <macrolist>sep
+ - bug corrigé dans \loi_restorecatcode
+
+v1.2 22/10/2016
+ - macros \greadlist et \gitemtomacro pour la globalité
+
+v1.3 18/11/2016
+ - bugs corrigés dans la gestion de la globalité
+
+v1.4 05/10/2017
+ - test \loi_ifprimitive ajouté au test \loi_ifcs
+ - suppression de \loi_expafternil, création de \loi_expafter,
+ modification de \loi_argcsname
+ - correction d'un bug : \setsepchar{\par} ne provoque plus
+ d'erreur. \loi_ifnum devient \long
+
+v1.5 06/10/2017
+ - correction d'un bug dans \loi_ifcs
+
+v1.51 24/10/2017
+ - correction d'un bug dans \loi_ifcs
+
+v1.52 13/01/2018
+ - le dernier séparateur est <vide>
+
+v1.53 13/03/2018
+ - correction d'un bug dans \readlist_g
+
+v1.6 01/11/2018
+ - possibilité d'appariement de tokens dans les items
+
+v1.61 03/03/2019
+ - la macro \loi_ifcs contient une erreur de conception.
+ Il faut tester si le token est un sc && s'il est
+ développable pour renvoyer vrai car il existe des sc
+ non développables && qui ne sont _pas_ des primitives.
+ Macro rebaptisée \loi_ifcsexpandable \ No newline at end of file
