<P>Boost 1.31.0.</P>
<UL>
<LI>
Completely rewritten pattern matching code - it is now up to 10 times faster
than before.
<LI>
Reorganized documentation.
<LI>
Deprecated all interfaces that are not part of the <A href="http://anubis.dkuug.dk/jtc1/sc22/wg21/docs/papers/2003/n1429.htm">
regular expression standardization proposal</A>.
<LI>
Added <A href="regex_iterator.html">regex_iterator</A> and <A href="regex_token_iterator.html">
regex_token_iterator</A>
.
<LI>
Added support for Perl style independent sub-expressions.
<LI>
Added non-member operators to the<A href="sub_match.html"> sub_match class</A>,
so that you can compare sub_match's with strings, or add them to a string to
produce a new string.
<LI>
Added experimental support for <A href="captures.html">extended capture
information</A>.
<LI>
Changed the match flags so that they are a distinct type (not an integer), if
you try to pass the match flags as an integer rather than<A href="match_flag_type.html">
match_flag_type</A> to the regex algorithms then you will now get a compiler
error.</LI></UL>
