Instead of: undefined label track-arche we have : undefined label `track-arche’ (first use at line 748). No more Strange keywords cha^{i}nes. Removed final dot in keywords. This is a valid keyword: c{\oe}ur. Implemented \oldstylenums like \textsuperscript and \textsubscript. Implemented \linebreak and \nolinebreak as no-op with optional argument. Tralics counts lines properly for Unix, Mac and Windows. If you say EDITOR = {A. Drouin & G. Eude & J.Robert} you get an error of the form bad syntax in author or editor name.
[version 1.9j, 2003-10-24] Added special hack for empty macros everywhere. Better error message for \addtolength{toto}{2cm}. Same for \addtolength{\toto}{2cm}.

Implemented \openout, \write and \closeout. Tralics signals unterminated \if conditions. This is ok: \iffalse \FPiflt{1}{2} \fi \toto \fi. Evaluating $\undef$ generates an understandable message. Evaluating $a^b^c$ gives now : double superscript.
[version 1.9k, 2003-10-30] Added a missing flush_buffer() in \bibitem. Command \newline invalid in table. Function T_bibitem was completely wrong… Attribute rowspan replaced by columnspan in math tables. Added a use_all_sizes option. [2003-10-30] Split file txparser.C into two parts. txscan.C is a new file. There is an indication in the log file whenever Tralics opens/closes a file. Commands \input and \endinput are fully expanded. Calls \input{foo} and \input foo are OK. Implicit call of save_the_state for \input (needed for \input A\input B). Functions \openin and \closein are always traced, but only sometimes on the tty. Call \catcode `A=9 works now. Function get_token completely rewritten. [print_mods]: this_line is never zero.

[2004-01-22] Changed array_info, it holds two vectors : u and v. Renamed class Buffer as buffer. Added support for German. Change: flush_buffer does not create a useless XML element. Made code of \par and Co clearer. Entities: Tralics may output   instead of  . This prints OK: \expandafter\show\csname^^I^^85^^97\endcsname. Bug: \catcode^^I` does not change the catcode of space. First cell in table does not start with space. Bug: \dj\DJ is OK now.
[2004-01-24] Commands added for \=t\=T\=h\=H etc. Correction to: `Seeing a closing brace does not call flush_buffer();’ needed also in by save_aux_boxend::unsave.

2002-12, Version 1.7

[date unknown] In bibtex, if the citation is numeric, optional argument in the alpha key. Partial handling of \begin inside comments. \catcode160=10. Said otherwise, nonbreakspace is considered as a normal space. Message duplicate field ignored becomes duplicate field `note’ ignored, in the case of a note. \href{toto}{\url{titi}} gives two errors unexpected element hi, invalid url value. the first message becomes: unexpected font change tt. if the second is printed, it will be you should perhaps use \href{url{x}}{y} instead of \href{y}{url{x}}. editor = "\textsc{toto}" in the biblio gives unexpected font change sc. maybe you confused Publisher with Editor. Bug corrections: \c{c} OK in a bibname; \v{c} OK ; \a'{e} OK. Some new commands: \sharp \natural \flat \oval \updownarrow \thinspace. Message Module name already seen replaced by Module name `result’ already seen. $_$ give no memory fault but Math formula should not finish with _ Calling tralics -all works.

Problems with tables. \footcite puts a space before.

Version 1.6

[date unknown] Implementation of \@ifundefined, \@ifstar, \@ifnextchar, \typeout. Added option interactivemath. This prints the formulas on the the screen. No file is read. Instead of a message like Undefined command \eta; command code = 157 you get Math only command \eta. Missing dollar not inserted. Definition of \begin{sloppypar} ... \end{sloppypar}. In an url, \~ is converted to a ~. In an url, _ is of catcode 13, and not 11, it is defined to be identical to \_. (problem of toto\_titi_tata). Definition of \epsfbox. A construction like $7^{mbox{scriptsize it i`{e}me}}$ works. It is like 7\ieme. Added \P, it is like ¶. Added \line \put \bezier \qbezier \vector \thicklines \thinlines \dashlike \drawline \dotteline. \begin{minipage}[][][]{} ... \end{minipage} is translated. Implementation of \begin{xmlelement} ... \end{xmlelement}.
Version 1.6b [date unknown] Implementation of \hbox, \vbox, \xbox etc. Silly bug \def\foo\xbox{\foo}{} loops without end. Correction of bugs in a token list. Bug in <<~ : superfluous space. Bug in \medskip\par\noindent. Added \mbox, \fbox, \makebox, \framebox with the syntax of picture. Added the picture environment. Added comment environnement. If the final brace \end{module} is missing Tralics does not say : Unexpected end of file but indicates the line containing the \end. If you say \htmladdnormallink{toto}(titi) (parentheses instead of braces) the error will be: Invalid URL value.
Version 1.6c [date unknown] Bug correction: the second \par in \par toto \par titi was ignored (synchronisation problem). Added \let\debugfalse\relax. Instead of putting the biblio in toto.bbl, I put it in toto_.bbl. Bug of \{ and \} in math mode, not completely handled. Bug of \item[{\bf x}]; braces disappear. Bug of \begin{Verbatim} [numbers=true]; the test of optional argument is strange. Bug of \, among others in math mode; there is an unwanted <mo>. Bug: editeur twice in case of @conference. Bug of \newcount{toto}[titi], the \let\cl@toto\@empty did ignore the reference count. Other bug in the biblio. $$toto$$titi inserts a \par\noindent. If you say \newcommand{\Athapascan0}{ok} the error message will be Attempt to define: \Athapascan 0, Error signaled at line 188: Only one token allowed in argument list. \moduleref[1539]{PROJET}{section}{module} is an error, because I don’t know how to translate into English (Everybody knows Marignan 1515).
Version 1.6d [date unknown] Implementation of \dotsc \dotsb \dotsi \dotsm it’s like \dots. \geqslant, \leqslant ok. [raweb-cfg.sty] \ell works fine. Added\let\href\htmladdnormallink. \not= and \not\in work. [rawebfo.xsl] added separateur.objet in citation/xref. Problem of \href{\url{&}}{&} This is accepted by the translator, but conversion to Pdf fails. Environment cases implemented. [raweb-cfg.sty] problem with \item : bullet non centered if TeX decides to start a new page because of the \penalty of the \item. Tralics signals an error if a) you say \label{x} \label{x}, b) you say \ref{x} without the associated \label, c) you say \ref and the label disappears [thanks JB Pomet]. a\over b gives <mfrac> rather than a <mover> [pb. I. Vatton]. Added namespaces in math elements. Order of biblio references changed. Implementation of \input, \endinput, \IfFileExists, \InputIfFileExists. Bug corrections: in \small, nothing happened; in \setbox3=\hbox{}, assignment was local; {\large \hbox{\small x}} gave an empty <large> in the hbox. \newcommand\foo{\begin{latexonly}... calls abort, instead of memory fault (project Trec). Some (Sans titre) disappear, other become (Sans Titre).

Version 1.5

[date unknown] \hspace allowed in maths. For instance $I\hspace{-0.1cm}R^n$ ; Not bad in Pdf, not recognized by amaya. The file wmachin.cfg is not created if invalid (following a mail of Vincent Lefèvre). Tralics looks at the shell variable TRALICSDIR before RAWEBDIR. Tralics copies catalog.src in catalog in the current working dir replacing source_directory by whatever needed (catalog.src is a new file, to be added in the package). \includegraphics{toto.ps}, \includegraphics{a.b.c} are translated into <graphics file='toto'/> <graphics file='a.b.c'/>. Correction of a silly bug for the Sharp Team. A second one. The error message Non character found in environment name: becomes Non-character found in \includegraphics. (For the Sharp Team). Added a new error message that reads Things like {'{}} are a bit strange (they use it for an apostrophe). Implementation of \uppercase, \lowercase, \MakeUppercase, \MakeLowercase. Add/test of the commands \oe\OE\o\O\ae\AE\dh\DH\dj\DJ\l\L\ng\NG\ss\SS\th\TH (\ng, \NG do not work, \dj is strange). Problem \oe does not work in HTML. \mbox{\sc Vasy} is translated as {\sc Vasy}. \begin{quote} ... \end{quote} is OK. Idem with flushleft and flushright. \raggedleft \raggedright OK. (must modify rawebhtml.xsl and rawebfo.xsl). \begin{wrapfigure}{x}{y} ... \end{wrapfigure} is handled as \begin{figure}[x] ... \end{figure}. (putting a figure near some text works only if somebody checks that the layout is OK). Silly bug. You should not see something like Checked 1 keyword env with 14 keywords (13 unique) because there are 15 words, all different. \ensuremath{\alpha} works. $\ensuremath{\beta}$ puts too many braces, but there are other functions that do the same. Must correct this one day.
