-\subsection{Compatibility with \file{german.sty}}\label{l-h}
+\section{Changes}
-The file \file{german.sty} has been one of the sources of inspiration
-for the \babel{} system. Because of this I wanted to include
-\file{german.sty} in the \babel{} system. To be able to do that I had
-to allow for one incompatibility: in the definition of the macro
-|\selectlanguage| in \file{german.sty} the argument is used as the
-{$\langle \it number \rangle$} for an |\ifcase|. So in this case a
-call to |\selectlanguage| might look like |\selectlanguage{\german}|.
+\subsection{Changes in \babel\ version 3.9}
-In the definition of the macro |\selectlanguage| in \file{babel.def}
-the argument is used as a part of other macronames, so a call to
-|\selectlanguage| now looks like |\selectlanguage{german}|. Notice
-the absence of the escape character. As of version~3.1a of \babel{}
-both syntaxes are allowed.
+Most of changes in version 3.9 are related to bugs, either to fix them
+(there were lots), or to provide some alternatives. Even new features
+like |\babelhyphen| are intended to solve a certain problem (in this
+case, the lacking of a uniform syntax and behaviour for shorthands
+across languages). These changes are described in this manual in the
+corresponding place. A selective list follows:
+\begin{itemize}
+\item |\select@language| did not set |\languagename|. This meant the
+ language in force when auxiliary files were loaded was the one used
+ in, for example, shorthands -- if the language was |german|, a
+ |\select@language{spanish}| had no effect.
-All other features of the original \file{german.sty} have been copied
-into a new file, called \file{germanb.sty}\footnote{The `b' is added
-to the name to distinguish the file from Partls' file.}.
+\item |\foreignlanguage| and |otherlanguage*| messed up
+ |\extras<language>|. Scripts, encodings and many other things were
+ not switched correctly.
-Although the \babel{} system was developed to be used with \LaTeX,
-some of the features implemented in the language definition files
-might be needed by plain \TeX\ users. Care has been taken that all
-files in the system can be processed by plain \TeX.
+\item The |:ENC| mechanism for hyphenation patterns used the encoding
+ of the \textit{previous} language, not that of the language being
+ selected.
-\subsection{Compatibility with \file{ngerman.sty}}
+\item |'| (with |activeacute|) had the original value when writing to an
+ auxiliary file, and things like an infinite loop could happen. It
+ worked incorrectly with |^| (if activated) and also if deactivated.
-When used with the options \Lopt{ngerman} or \Lopt{naustrian},
-\babel{} will provide all features of the package \pkg{ngerman}.
-There is however one exception: The commands for special hyphenation
-of double consonants (|"ff| etc.) and ck (|"ck|), which are no longer
-required with the new German orthography, are undefined. With the
-\pkg{ngerman} package, however, these commands will generate
-appropriate warning messages only.
+\item Active chars where not reset at the end of language options, and
+ that lead to incompatibilities between languages.
-\subsection{Compatibility with the \pkg{french} package}
+\item |\textormath| raised and error with a conditional.
-It has been reported to me that the package \pkg{french} by Bernard
-Gaulle (\texttt{gaulle@idris.fr}) works together with \babel. On the
-other hand, it seems \emph{not} to work well together with a lot of
-other packages. Therefore I have decided to no longer load
-\file{french.ldf} by default. Instead, when you want to use the
-package by Bernard Gaulle, you will have to request it specifically,
-by passing either \Lopt{frenchle} or \Lopt{frenchpro} as an option to
-\babel.
+\item |\aliasshorthand| didn't work (or only in a few and very specific
+ cases).
-\subsection{Changes in \babel\ version 3.9}
+\item |\l@english| was defined incorrectly (using |\let| instead of
+ |\chardef|).
-Most of changes in version 3.9 are related to bugs, either to fix them

+% \section{Hooks for XeTeX and LuaTeX}
+%
+% \subsection{XeTeX}
+%
+% Unfortunately, the current encoding cannot be retrieved and
+% therefore it is reset always to |utf8|, which seems a sensible
+% default.
+%
+% \LaTeX{} sets many ``codes'' just before loading
+% \verb|hyphen.cfg|. That is not a problem in luatex, but in xetex
+% they must be reset to the proper value. Most of the work is done in
+% \textsf{xe(la)tex.ini}, so here we just ``undo'' some of the
+% changes done by \LaTeX. Anyway, for consistency Lua\TeX{} also
+% resets the catcodes.

+%
+% \subsection{LuaTeX}
+%
+% The new loader for luatex is based solely on |language.dat|, which
+% is read on the fly. The code shouldn't be executed when the format
+% is build, so we check if |\AddBabelHook| is defined. Then comes a
+% modified version of the loader in |hyphen.cfg| (without the
+% hyphenmins stuff, which is under the direct control of \babel).
+%
+% The names |\l@<language>| are defined and take some value from the
+% beginning because all \texttt{ldf} files assume this for the
+% corresponding language to be considered valid, but patterns are not
+% loaded (except the first one). This is done later, when the language
+% is first selected (which usually means when the \texttt{ldf}
+% finishes). If a language has been loaded, |\bbl@hyphendata@<num>|
+% exists (with the names of the files read).
+%
+% The default setup preloads the first language into the format. This
+% is intended mainly for `english', so that it's available without
+% further intervention from the user. To avoid duplicating it, the
+% following rule applies: if the ``0th'' language and the first
+% language in |language.dat| have the same name then just ignore the
+% latter. If there are new synonymous, the are added, but note if the
+% language patterns have not been preloaded they won't at run time.
+%
+% Other preloaded languages could be read twice, if they has been
+% preloaded into the format. This is not optimal, but it shouldn't
+% happen very often -- with \luatex{} patterns are best loaded when
+% the document is typeset, and the ``0th'' language is preloaded just
+% for backwards compatibility.
+%
+% As of 1.1b, lua(e)tex is taken into account. Formerly, loading of
+% patterns on the fly didn't work in this format, but with the new
+% loader it does. Unfortunately, the format is not based on \babel,
+% and data could be duplicated, because languages are reassigned above
+% those in the format (nothing serious, anyway). Note even with this
+% format |language.dat| is used (under the principle of a single
+% source), instead of |language.def|.
+%
+% Of course, there is room for improvements, like tools to read and
+% reassign languages, which would require modifying the language list,
+% and better error handling.
+%
+% We need catcode tables, but no format (targeted by \babel) provide a
+% command to allocate them (although there are packages like
+% \textsf{ctablestack}). For the moment, a dangerous approach is used
+% -- just allocate a high random number and cross the fingers. To
+% complicate things, \textsf{etex.sty} changes the way languages are
+% allocated.
