+[[v4.1.0_nick_color_infos]]
+=== Nick color infos
+
+Two infos to get nick colors have been added: nick_color_ignore_case and
+nick_color_name_ignore_case. +
+They are similar to nick_color and nick_color_name, except they take as second
+argument a range of chars to apply on the nick: the nick is converted to lower
+case using this range of chars.
+
+The infos irc_nick_color and irc_nick_color_name, that were deprecated since
+version 1.5 are now used again, with a change in parameter: the server is now
+optional before the nick: "server,nick". +
+The nick is first converted to lower case, following the value of CASEMAPPING
+on the server, then hashed to compute the color. +
+That means the color for a nick is now case insensitive (in the way IRC servers
+are case insensitive, so with a limited range of chars only).
+
+If a script was using this info with a comma in nickname (which should not happen
+anyway), this is now interpreted as the server name, and the script must be
+modified. +
+Anyway, it is recommended to always give the server name to respect the
+CASEMAPPING of the server and prevent any issue with a comma in the nickname.
+
+For example nick color of "alice" and "ALICE" is now always guaranteed to be the
+same:
+
+----
+# with server name (recommended)

+=== Ich möchte mein WeeChat auf ein anderes Gerät verschieben und meine Konfiguration behalten. Was muss ich kopieren?
+
+Überprüfen Sie zunächst die von WeeChat verwendeten Verzeichnisse mit diesem Befehl: `/debug dirs`. +
+Die Verzeichnisse home/config und home/data müssen kopiert werden (alle Dateien und Unterverzeichnisse).
+
+Falls beispielsweise XDG-Verzeichnisse verwendet werden (Standard bei WeeChat ≥ 3.2), sollten die
+Verzeichnisse `$HOME/.config/weechat` und `$HOME/.local/share/weechat` lauten. +
+Sollte ein einzelnes Verzeichnis verwenden werden (Standard bei WeeChat < 3.2), sollte das Verzeichnis
+`$HOME/.weechat` lauuten.
+
+[IMPORTANT]
+Die WeeChat-Version auf dem Zielgerät muss größer oder gleich der Version sein des Ausganggerätes. +
+Ein Downgrade der WeeChat-Konfiguration wird *NICHT UNTERSTÜTZT* und kann zu Schäden führen und ein
+unbrauchbares WeeChat verursachen.
+
+Schritte:
+
+. Weechat beenden: `/quit` (oder `/upgrade -quit`, falls eine Sitzung fortgesetzt werden soll,
+  einschließlich des Inhalts aller Buffer).
+. Kopieren Sie alle Verzeichnisse, Unterverzeichnisse und Dateien auf das neue Gerät und behalten Sie die
+  Namen und Berechtigungen bei.
+. Optional: Kopieren Sie alle Dateien außerhalb dieser Verzeichnisse, die auf Ihre Konfiguration verweisen
+  (es wird nicht empfohlen, Dateien außerhalb von WeeChat-Verzeichnissen zu verwenden).
+. WeeChat auf dem neuen Gerät starten: `weechat` (oder `weechat --upgrade`, falls die Sitzung gesichert wurde).

+[[move_to_another_device]]
+=== I want to move my WeeChat to another device and keep my config, what should I copy?
+
+First check directories used by WeeChat with this command: `/debug dirs`. +
+Directories home/config and home/data must be copied (all files and sub-directories).
+
+For example if you're using XDG directories (default with WeeChat ≥ 3.2),
+the directories should be `$HOME/.config/weechat` and `$HOME/.local/share/weechat`. +
+If you're using a single directory (default with WeeChat < 3.2), the directory
+should be `$HOME/.weechat`.
+
+[IMPORTANT]
+The WeeChat version on the new device must be greater than or equal to the version
+on the initial device. +
+Downgrading WeeChat configuration is *NOT SUPPORTED* and can break it,
+leading to unusable WeeChat.
+
+Steps:
+
+. Quit Weechat: `/quit` (or `/upgrade -quit` if you want to resume the session,
+  which includes content of all buffers).
+. Copy all directories, sub-directories and files to the new device, keeping
+  same names and permissions.
+. Optional: copy any file outside these directories that you refer to in your
+  configuration (it's not recommended to use files outside WeeChat directories).
+. Start WeeChat on the new device: `weechat` (or `weechat --upgrade` if you
+  saved the session).

+=== I want to move my WeeChat to another device and keep my config, what should I copy?
+
+First check directories used by WeeChat with this command: `/debug dirs`. +
+Directories home/config and home/data must be copied (all files and sub-directories).
+
+For example if you're using XDG directories (default with WeeChat ≥ 3.2),
+the directories should be `$HOME/.config/weechat` and `$HOME/.local/share/weechat`. +
+If you're using a single directory (default with WeeChat < 3.2), the directory
+should be `$HOME/.weechat`.
+
+[IMPORTANT]
+The WeeChat version on the new device must be greater than or equal to the version
+on the initial device. +
+Downgrading WeeChat configuration is *NOT SUPPORTED* and can break it,
+leading to unusable WeeChat.
+
+Steps:

+=== Je souhaite déplacer mon WeeChat vers une autre machine et garder ma configuration, que dois-je copier ?
+
+Premièrement, vérifiez les répertoires utilisés par WeeChat avec cette commande :
+`/debug dirs`. +
+Les répertoires home/config et home/data doivent être copiés (tous les fichiers
+et sous-répertoires).
+
+Par exemple si vous utilisez les répertoires XDG (par défaut avec WeeChat ≥ 3.2),
+les répertoires devraient être `$HOME/.config/weechat` et `$HOME/.local/share/weechat`. +
+Si vous utilisez un répertoire unique (par défaut avec WeeChat < 3.2), le répertoire
+devrait être `$HOME/.weechat`.
+
+[IMPORTANT]
+La version de WeeChat sur la nouvelle machine doit être supérieure ou égale
+à celle de la machine initiale. +
+La rétrogradation de la configuration n'est *PAS SUPPORTÉE* et pourrait la casser,
+rendant WeeChat inutilisable.
+
+Étapes :
+
+. Quitter Weechat : `/quit` (ou `/upgrade -quit` si vous souhaitez restaurer
+  la session, qui inclut le contenu de tous les tampons).
+. Copier tous les répertoires, fichiers et sous-répertoires vers la nouvelle machine
+  au même endroit, en préservant les noms et les permissions.
+. Facultatif : copier tout fichier en dehors de ces répertoires que vous référencez
+  dans votre configuration (il n'est pas recommandé d'utiliser des fichiers en
+  dehors des répertoires WeeChat).
+. Démarrer WeeChat sur la nouvelle machine : `weechat` (ou `weechat --upgrade`
+  si vous avez sauvé la session).

+=== I want to move my WeeChat to another device and keep my config, what should I copy?
+
+First check directories used by WeeChat with this command: `/debug dirs`. +
+Directories home/config and home/data must be copied (all files and sub-directories).
+
+For example if you're using XDG directories (default with WeeChat ≥ 3.2),
+the directories should be `$HOME/.config/weechat` and `$HOME/.local/share/weechat`. +
+If you're using a single directory (default with WeeChat < 3.2), the directory
+should be `$HOME/.weechat`.
+
+[IMPORTANT]
+The WeeChat version on the new device must be greater than or equal to the version
+on the initial device. +
+Downgrading WeeChat configuration is *NOT SUPPORTED* and can break it,
+leading to unusable WeeChat.
+
+Steps:
+
+. Quit Weechat: `/quit` (or `/upgrade -quit` if you want to resume the session,
+  which includes content of all buffers).
+. Copy all directories, sub-directories and files to the new device, keeping
+  same names and permissions.
+. Optional: copy any file outside these directories that you refer to in your
+  configuration (it's not recommended to use files outside WeeChat directories).
+. Start WeeChat on the new device: `weechat` (or `weechat --upgrade` if you
+  saved the session).

+[[move_to_another_device]]
+=== I want to move my WeeChat to another device and keep my config, what should I copy?
+
+First check directories used by WeeChat with this command: `/debug dirs`. +
+Directories home/config and home/data must be copied (all files and sub-directories).
+
+For example if you're using XDG directories (default with WeeChat ≥ 3.2),
+the directories should be `$HOME/.config/weechat` and `$HOME/.local/share/weechat`. +
+If you're using a single directory (default with WeeChat < 3.2), the directory
+should be `$HOME/.weechat`.
+
+[IMPORTANT]
+The WeeChat version on the new device must be greater than or equal to the version
+on the initial device. +
+Downgrading WeeChat configuration is *NOT SUPPORTED* and can break it,
+leading to unusable WeeChat.
+
+Steps:
+
+. Quit Weechat: `/quit` (or `/upgrade -quit` if you want to resume the session,
+  which includes content of all buffers).
+. Copy all directories, sub-directories and files to the new device, keeping
+  same names and permissions.
+. Optional: copy any file outside these directories that you refer to in your
+  configuration (it's not recommended to use files outside WeeChat directories).
+. Start WeeChat on the new device: `weechat` (or `weechat --upgrade` if you
+  saved the session).

+=== I want to move my WeeChat to another device and keep my config, what should I copy?
+
+First check directories used by WeeChat with this command: `/debug dirs`. +
+Directories home/config and home/data must be copied (all files and sub-directories).
+
+For example if you're using XDG directories (default with WeeChat ≥ 3.2),
+the directories should be `$HOME/.config/weechat` and `$HOME/.local/share/weechat`. +
+If you're using a single directory (default with WeeChat < 3.2), the directory
+should be `$HOME/.weechat`.
+
+[IMPORTANT]
+The WeeChat version on the new device must be greater than or equal to the version
+on the initial device. +
+Downgrading WeeChat configuration is *NOT SUPPORTED* and can break it,
+leading to unusable WeeChat.
+
+Steps:
+
+. Quit Weechat: `/quit` (or `/upgrade -quit` if you want to resume the session,
+  which includes content of all buffers).
+. Copy all directories, sub-directories and files to the new device, keeping
+  same names and permissions.
+. Optional: copy any file outside these directories that you refer to in your
+  configuration (it's not recommended to use files outside WeeChat directories).
+. Start WeeChat on the new device: `weechat` (or `weechat --upgrade` if you
+  saved the session).

+[[move_to_another_device]]
+=== I want to move my WeeChat to another device and keep my config, what should I copy?
+
+First check directories used by WeeChat with this command: `/debug dirs`. +
+Directories home/config and home/data must be copied (all files and sub-directories).
+
+For example if you're using XDG directories (default with WeeChat ≥ 3.2),
+the directories should be `$HOME/.config/weechat` and `$HOME/.local/share/weechat`. +
+If you're using a single directory (default with WeeChat < 3.2), the directory
+should be `$HOME/.weechat`.
+
+[IMPORTANT]
+The WeeChat version on the new device must be greater than or equal to the version
+on the initial device. +
+Downgrading WeeChat configuration is *NOT SUPPORTED* and can break it,
+leading to unusable WeeChat.
+
+Steps:
+
+. Quit Weechat: `/quit` (or `/upgrade -quit` if you want to resume the session,
+  which includes content of all buffers).
+. Copy all directories, sub-directories and files to the new device, keeping
+  same names and permissions.
+. Optional: copy any file outside these directories that you refer to in your
+  configuration (it's not recommended to use files outside WeeChat directories).
+. Start WeeChat on the new device: `weechat` (or `weechat --upgrade` if you
+  saved the session).
