* [#8059](https://bugzilla.scilab.org/8059): A local `.wgetrc` config file could make troubles in `atomsDownload`.
* [#9909](https://bugzilla.scilab.org/9909): In the help browser, add a way to open the online version of the current page.
* [#12889](https://bugzilla.scilab.org/12889): In the help browser, add a menu allowing to select the language of help pages, regardless of the language of the session.
+* [#14873](https://bugzilla.scilab.org/14873): `setfield` page: The output and the 6.0 history were documented only on the en_US version. The input was wrongly restricted to matrices, while any Scilab object is acceptable. The specific role of `setfield` for mlists was not really described nor illustrated. The example did not include any call to setfield.

<para>
- This function is an equivalent of <code>l(i)=x</code> syntax for field
- extraction with the only difference that it also applies to
- <literal>mlist</literal> objects.
+ <literal>L=setfield(a,v,L)</literal> addresses and changes the
+ i<superscript>th</superscript> element of a list, in a unified way
+ over lists, tlists and mlists.
+ </para>
+ <para>
+ For simple lists and for tlists, <literal>L=setfield(a,v,L)</literal>
+ is equivalent to <literal>L(a)=v</literal>, that is simpler and should be preferred.
+ The same stands for any mlist if the address <varname>a</varname> is a
+ field's name.
+ </para>
+ <para>
+ However, for any mlist L, if <literal>i</literal> is an index, the insertion
+ <literal>L(i)=v</literal> is not predefined, in order to let the user define
+ an overload implementing a matrix-oriented insertion, if required.
+ Yet <literal>setfield(i,v,L)</literal> is always defined, with the same meaning as

<para>
- Cette fonction est équivalente à la syntaxe <literal>l(i)=x</literal> pour l'extraction avec la seule différence qu'elle s'applique aussi aux objets de type <literal>mlist</literal>.
+ <literal>L=setfield(a,v,L)</literal> adresse et modifie le

+ </para>
+ <para>
+ Pour des simples list et pour des mlist, <literal>L=setfield(a,v,L)</literal>
+ est équivalent à <literal>L(a)=v</literal>, qui est plus simple et préférable.
+ L'équivalence tient aussi pour toute mlist si l'adresse <varname>a</varname>
+ est le nom d'un champ.
+ </para>
+ <para>
+ En revanche, pour toute mlist <varname>L</varname>, si <literal>i</literal>
+ est un n°, <literal>L(i)=v</literal> adresse le i<superscript>ème</superscript>
+ élément de <varname>L</varname> considérée comme un vecteur, au lieu
+ du i<superscript>ème</superscript> élément tel que déclaré dans la
+ définition initiale <literal>mlist(c1,c2,c3...)</literal>.
+ <literal>setfield(i,v,L)</literal> aura alors le même sens que pour les

<title>Descrição</title>
<para>
- Esta função é equivalente à sintaxe <literal>l(i)=x</literal> spara
- inserção de campos, com a única diferença de que também se aplica a
- objetos <literal>mlist</literal>.
+ <literal>L=setfield(a,v,L)</literal> addresses and changes the
+ i<superscript>th</superscript> element of a list, in a unified way
+ over lists, tlists and mlists.
+ </para>
+ <para>
+ For simple lists and for tlists, <literal>L=setfield(a,v,L)</literal>
+ is equivalent to <literal>L(a)=v</literal>, that is simpler and should be preferred.
+ The same stands for any mlist if the address <varname>a</varname> is a
+ field's name.
+ </para>
+ <para>
+ However, for any mlist L, if <literal>i</literal> is an index, the insertion
+ <literal>L(i)=v</literal> is not predefined, in order to let the user define
+ an overload implementing a matrix-oriented insertion, if required.
+ Yet <literal>setfield(i,v,L)</literal> is always defined, with the same meaning as
+ for other list and tlist types.
</para>

<title>Exemplos</title>
+ <para>
+ For a tlist, <literal>setfield(3, v, T)</literal> is equivalent to
+ <literal>T(3)=v</literal> :
+ </para>
+ <programlisting role="example"><![CDATA[
+T = tlist(['V','a','b'], [%z (1-%z) %z^2], [%f %t %t]);
+// The insertion is predefined:
+T(3) = [%t %t %f];
+T(3)
+
+T = setfield(3, [%f %t %f], T);
+T(3)
+ ]]></programlisting>
+ <screen><![CDATA[

+ T T F
+
+--> T = setfield(3, [%f %t %f], T);
+--> T(3)
+ ans =
+ F T F
+]]></screen>
+ <para>
+ For a mlist, there is no predefined indexed insertion routine, to let
+ the user define a matrix-oriented insertion overload if required.
+ </para>
<programlisting role="example"><![CDATA[

<title>Описание</title>
<para>
- Эта функция является эквивалентом синтаксиса <code>l(i)=x</code>
- для вставки поля с той лишь разницей, что она также применима к объектам <literal>mlist</literal>.
+ <literal>L=setfield(a,v,L)</literal> адресует и изменяет
+ i<superscript>й</superscript> элемент списка унифицированным образом
+ среди списков типа list, tlist и mlist.
+ </para>
+ <para>
+ Для простых списков (list) и для типизированных списков (tlist),
+ <literal>L=setfield(a,v,L)</literal> эквивалентно <literal>L(a)=v</literal>,
+ то есть проще и должно быть предпочтительнее. Аналогично для любого
+ матричноориентированного списка (mlist), если адрес <varname>a</varname>
+ является именем поля.
+ </para>
+ <para>
+ Тем не менее, для любого матричноориентированного списка
+ <varname>L</varname>, если <literal>i</literal> является индексом, то
+ вставка <literal>L(i)=v</literal> не предопределена, для того, чтобы
+ позволить пользователю определить перегрузку, реализующую
+ матричноориентированную вставку, если требуется. Вот
+ <literal>setfield(i,v,L)</literal> всегда определена, с тем же смыслом,
+ что и для других списков типа list и tlist.
