<expand|section|Document format (0.3.4)>
The TeXmacs document format has profoundly changed in order to make TeXmacs
compatible with XML in the future. Most importantly, the old style
environments like\
<\verbatim>
\ \ \ \ \<less\>assign\|env\|\<less\>environment\|open\|close\<gtr\>\<gtr\
\>,
</verbatim>
which are applied via matching pairs <verbatim|\<less\>begin\|env\<gtr\>tex\
t\<less\>end\|env\<gtr\>>, have been replaced by macros\
<\verbatim>
\ \ \ \ \<less\>assign\|env\|\<less\>macro\|body\|open\<less\>body\<gtr\>\
close\<gtr\>\<gtr\>,
</verbatim>
which are applied via single macro expansions
<verbatim|\<less\>expand\|env\|text\<gtr\>>. Similarly, matching pairs
<verbatim|\<less\>set\|var\|val\<gtr\>text\<less\>reset\|var\<gtr\>> of
environment variable changes are replaced by a
<verbatim|\<less\>with\|var\|val\|text\<gtr\>> construct (close to XML
attributes). From a technical point of view, these changes lead to several
complications if the <verbatim|text> body consists of several paragraphs.
As a consequence, badly structured documents may sometimes display
differently in the new version (although I only noticed one minor change in
my own documents). Furthermore, in order to maintain the higher level of
structure in the document, the behaviour of the editor in relation to
multiparagraph environments has slightly changed.
