| <li> |
| Fixed broken makefiles. |
| </li> |
| <li> |
| Fixed configuration setup to allow building with VC7.1 - STLport-4.6.2 |
| when using /Zc:wchar_t. |
| </li> |
| <li> |
| Moved declarations class-inline in static_mutex.hpp so that SGI Irix |
| compiler can cope. |
| </li> |
| <li> |
| Added needed standard library #includes to fileiter.hpp, regex_workaround.hpp |
| and cpp_regex_traits.hpp. |
| </li> |
| <li> |
| Fixed a bug where non-greedy repeats could in certain strange curcumstances |
| repeat more times than their maximum value. |
| </li> |
| <li> |
| Fixed the value returned by basic_regex<>::empty() from a default |
| constructed object. |
| </li> |
| <li> |
| Changed the deffinition of regex_error to make it backwards compatible |
| with Boost-1.32.0. |
| </li> |
| <li> |
| Disabled external templates for Intel C++ 8.0 and earlier - otherwise |
| unresolved references can occur. |
| </li> |
| <li> |
| Rewritten extern template code for gcc so that only specific member functions |
| are exported: otherwise strange unresolved references can occur when |
| linking and mixing debug and non-debug code. |
| </li> |
| <li> |
| Initialise all the data members of the unicode_iterators: this keeps |
| gcc from issuing needless warnings. |
| </li> |
| <li> |
| Ported the ICU integration code to VC6 and VC7. |
| </li> |
| <li> |
| Ensured code is STLport debug mode clean. |
| </li> |
| <li> |
| Fixed lookbehind assertions so that fixed length repeats are permitted, |
| and so that regex iteration allows lookbehind to look back before the |
| current search range (into the last match). |
| </li> |
| <li> |
| Fixed strange bug with non-greedy repeats inside forward lookahead assertions. |
| </li> |
| <li> |
| Enabled negated character classes inside character sets. |
| </li> |
| <li> |
| Fixed regression so that [a-z-] is a valid expression again. |
| </li> |
| <li> |
| Fixed bug that allowed some invalid expressions to be accepted. |

| <div class="itemizedlist"><ul type="disc"> |
| <li> |
| Completely rewritten expression parsing code, and traits class support; |
| now conforms to the standardization proposal. |
| </li> |
| <li> |
| Breaking Change: The syntax options that can be passed to basic_regex |
| constructors have been rationalized. The default option (perl) now has |
| a value of zero, and it is now clearly documented which options apply |
| to which regular expression syntax styles (perl, POSIX-extended, POSIX-basic |
| etc). Some of the more esoteric options have now been removed, so there |
| is the possibility that existing code may fail to compile: however equivalent |
| functionality should still be available. |
| </li> |
| <li> |
| Breaking Change: POSIX-extended and POSIX-basic regular expressions now |
| enforce the letter of the POSIX standard much more closely than before. |
| </li> |
| <li> |
| Added support for (?imsx-imsx) constructs. |
| </li> |
| <li> |
| Added support for lookbehind expressions (?<=positive-lookbehind) |
| and (?<!negative-lookbehind). |
| </li> |
| <li> |
| Added support for conditional expressions (?(assertion)true-expresion|false-expression). |
| </li> |
| <li> |
| Added MFC/ATL string wrappers. |
| </li> |
| <li> |
| Added Unicode support; based on ICU. |
| </li> |
| <li> |
| Changed newline support to recognise \f as a line separator (all character |
| types), and \x85 as a line separator for wide characters / Unicode only. |
| </li> |
| <li> |
| Added a new format flag format_literal that treats the replace string |
| as a literal, rather than a Perl or Sed style format string. |
| </li> |
| <li> |
| Errors are now reported by throwing exceptions of type regex_error. The |
| types used previously - bad_expression and bad_pattern - are now just |
| typedefs for regex_error. Type regex_error has a couple of new members: |
| code() to report an error code rather than a string, and position() to |
| report where in the expression the error occured. |

| Reorganized documentation. |
| </li> |
| <li> |
| Deprecated all interfaces that are not part of the regular expression |
| standardization proposal. |
| </li> |
| <li> |
| Added regex_iterator and regex_token_iterator . |
| </li> |
| <li> |
| Added support for Perl style independent sub-expressions. |
| </li> |
| <li> |
| Added non-member operators to the sub_match class, so that you can compare |
| sub_match's with strings, or add them to a string to produce a new string. |
| </li> |
| <li> |
| Added experimental support for extended capture information. |
| </li> |
| <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 match_flag_type |
| to the regex algorithms then you will now get a compiler error. |
