Note however, that 41(*MARK) and operations on marks are not currently supported. 42* Fix incorrect range end when matching \[\[:unicode:\]\], see [@https://svn.boost.org/trac/boost/ticket/11524 #11524]. 43* Change POSIX reg_comp API to not check potentially uninitialized memory, note that code which was previously free from memory 44leaks (but none the less buggy, as it didn't call reg_free) will now leak. See [@https://svn.boost.org/trac/boost/ticket/11472 #11472]. 45* Make sub_match a valid C++ range type, see [@https://svn.boost.org/trac/boost/ticket/11036 #11036]. 46 47[h4 Boost.Regex-5.0.1 (Boost-1.58.0)] 48 49* Fixed some typos as in [@https://svn.boost.org/trac/boost/ticket/10682 #10682]. 50* Merged [@https://github.com/boostorg/regex/pull/6 pull-request #6] for Coverity warnings. 51* Merged [@https://github.com/boostorg/regex/pull/7 pull-request #7] for Coverity warnings. 52* Merged [@https://github.com/boostorg/regex/pull/8 pull-request #8] for Coverity warnings. 53* Merged [@https://github.com/boostorg/regex/pull/10 pull-request #10] to enable more build variants when linking to ICU. 54* Fix issue with ICU and partial matches, see [@https://svn.boost.org/trac/boost/ticket/10114 #10114]. 55* Removed delayload support for the ICU libraries: this doesn't work with the latest ICU releases (linker errors). 56 57 58[h4 Boost.Regex-5.0.0 (Boost-1.56.0)] 59 60* Moved to library-specific version number post the move to Git. And since we have one (minor) breaking change 61this gets bumped up from v4 to v5. 62* [*Breaking change:] corrected behavior of `basic_regex<>::mark_count()` to match existing documentation, 63`basic_regex<>::subexpression(n)` changed to match, see [@https://svn.boost.org/trac/boost/ticket/9227 #9227] 64* Fixed issue [@https://svn.boost.org/trac/boost/ticket/8903 #8903]. 65* Fixed documentation typos from [@https://svn.boost.org/trac/boost/ticket/9283 #9283]. 66* Fixed bug in collation code that failed if the locale generated collation strings with embedded nul's, 67see [@https://svn.boost.org/trac/boost/ticket/9451 #9451]. 68* Apply patch for unusual thread usage (no statically initialized mutexes), see [@https://svn.boost.org/trac/boost/ticket/9461 #9461]. 69* Added better checks for invalid UTF-8 sequences, see [@https://svn.boost.org/trac/boost/ticket/9473 #9473]. 70 71[h4 Boost-1.54] 72 73Fixed issue [@https://svn.boost.org/trac/boost/ticket/8569 #8569]. 74 75[h4 Boost-1.53] 76 77Fixed Issues: 78[@https://svn.boost.org/trac/boost/ticket/7744 #7744], [@https://svn.boost.org/trac/boost/ticket/7644 #7644]. 79 80[h4 Boost-1.51] 81 82Fixed issues: 83[@https://svn.boost.org/trac/boost/ticket/589 #589], [@https://svn.boost.org/trac/boost/ticket/7084 #7084], 84[@https://svn.boost.org/trac/boost/ticket/7032 #7032], [@https://svn.boost.org/trac/boost/ticket/6346 #6346]. 85 86[h4 Boost-1.50] 87 88Fixed issue with `(?!)` not being a valid expression, and updated docs on what constitutes a valid conditional expression. 89 90[h4 Boost-1.48] 91 92Fixed issues: 93[@https://svn.boost.org/trac/boost/ticket/688 #698], [@https://svn.boost.org/trac/boost/ticket/5835 #5835], 94[@https://svn.boost.org/trac/boost/ticket/5958 #5958], [@https://svn.boost.org/trac/boost/ticket/5736 #5736]. 95 96 97[h4 Boost 1.47] 98 99Fixed issues: 100[@https://svn.boost.org/trac/boost/ticket/5223 #5223], [@https://svn.boost.org/trac/boost/ticket/5353 #5353], 101[@https://svn.boost.org/trac/boost/ticket/5363 #5363], [@https://svn.boost.org/trac/boost/ticket/5462 #5462], 102[@https://svn.boost.org/trac/boost/ticket/5472 #5472], [@https://svn.boost.org/trac/boost/ticket/5504 #5504]. 103 104[h4 Boost 1.44] 105 106Fixed issues: 107[@https://svn.boost.org/trac/boost/ticket/4309 #4309], 108[@https://svn.boost.org/trac/boost/ticket/4215 #4215], 109[@https://svn.boost.org/trac/boost/ticket/4212 #4212], 110[@https://svn.boost.org/trac/boost/ticket/4191 #4191], 111[@https://svn.boost.org/trac/boost/ticket/4132 #4132], 112[@https://svn.boost.org/trac/boost/ticket/4123 #4123], 113[@https://svn.boost.org/trac/boost/ticket/4114 #4114], 114[@https://svn.boost.org/trac/boost/ticket/4036 #4036], 115[@https://svn.boost.org/trac/boost/ticket/4020 #4020], 116[@https://svn.boost.org/trac/boost/ticket/3941 #3941], 117[@https://svn.boost.org/trac/boost/ticket/3902 #3902], 118[@https://svn.boost.org/trac/boost/ticket/3890 #3890] 119 120[h4 Boost 1.42] 121 122* Added support for Functors rather than strings as format expressions. 123* Improved error reporting when throwing exceptions to include better more relevant information. 124* Improved performance and reduced stack usage of recursive expressions. 125* Fixed tickets 126[@https://svn.boost.org/trac/boost/ticket/2802 #2802], 127[@https://svn.boost.org/trac/boost/ticket/3425 #3425], 128[@https://svn.boost.org/trac/boost/ticket/3507 #3507], 129[@https://svn.boost.org/trac/boost/ticket/3546 #3546], 130[@https://svn.boost.org/trac/boost/ticket/3631 #3631], 131[@https://svn.boost.org/trac/boost/ticket/3632 #3632], 132[@https://svn.boost.org/trac/boost/ticket/3715 #3715], 133[@https://svn.boost.org/trac/boost/ticket/3718 #3718], 134[@https://svn.boost.org/trac/boost/ticket/3763 #3763], 135[@https://svn.boost.org/trac/boost/ticket/3764 #3764] 136 137[h4 Boost 1.40] 138 139* Added support for many Perl 5.10 syntax elements including named 140sub-expressions, branch resets and recursive regular expressions. 141 142[h4 Boost 1.38] 143 144* [*Breaking change]: empty expressions, and empty alternatives are now 145allowed when using the Perl regular expression syntax. This change has 146been added for Perl compatibility, when the new [syntax_option_type] 147['no_empty_expressions] is set then the old behaviour is preserved and 148empty expressions are prohibited. This is issue 149[@https://svn.boost.org/trac/boost/ticket/1081 #1081]. 150* Added support for Perl style ${n} expressions in format strings 151(issue [@https://svn.boost.org/trac/boost/ticket/2556 #2556]). 152* Added support for accessing the location of sub-expressions within the 153regular expression string 154(issue [@https://svn.boost.org/trac/boost/ticket/2269 #2269]). 155* Fixed compiler compatibility issues 156[@https://svn.boost.org/trac/boost/ticket/2244 #2244], 157[@https://svn.boost.org/trac/boost/ticket/2514 #2514], 158and 159[@https://svn.boost.org/trac/boost/ticket/2244 #2458]. 160 161 162[h4 Boost 1.34] 163 164* Fix for non-greedy repeats and partial matches not working correctly in some cases. 165* Fix for non-greedy repeats on VC++ not working in some cases (bug report 1515830). 166* Changed match_results::position() to return a valid result when *this represents a partial match. 167* Fixed the grep and egrep options so that the newline character gets treated the same as |. 168 169[h4 Boost 1.33.1] 170 171* Fixed broken makefiles. 172* Fixed configuration setup to allow building with VC7.1 - STLport-4.6.2 when using /Zc:wchar_t. 173* Moved declarations class-inline in static_mutex.hpp so that SGI Irix compiler can cope. 174* Added needed standard library #includes to fileiter.hpp, regex_workaround.hpp and cpp_regex_traits.hpp. 175* Fixed a bug where non-greedy repeats could in certain strange circumstances repeat more times than their maximum value. 176* Fixed the value returned by basic_regex<>::empty() from a default constructed object. 177* Changed the definition of regex_error to make it backwards compatible with Boost-1.32.0. 178* Disabled external templates for Intel C++ 8.0 and earlier - otherwise unresolved references can occur. 179* 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. 180* Initialise all the data members of the unicode_iterators: this keeps gcc from issuing needless warnings. 181* Ported the ICU integration code to VC6 and VC7. 182* Ensured code is STLport debug mode clean. 183* 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). 184* Fixed strange bug with non-greedy repeats inside forward lookahead assertions. 185* Enabled negated character classes inside character sets. 186* Fixed regression so that [a-z-] is a valid expression again. 187* Fixed bug that allowed some invalid expressions to be accepted. 188 189[h4 Boost 1.33.0] 190 191* Completely rewritten expression parsing code, and traits class support; now conforms to the standardization proposal. 192* 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. 193* Breaking Change: POSIX-extended and POSIX-basic regular expressions now enforce the letter of the POSIX standard much more closely than before. 194* Added support for (?imsx-imsx) constructs. 195* Added support for lookbehind expressions (?<=positive-lookbehind) and (?<!negative-lookbehind). 196* Added support for conditional expressions (?(assertion)true-expression|false-expression). 197* Added MFC/ATL string wrappers. 198* Added Unicode support; based on ICU. 199* Changed newline support to recognise \\f as a line separator (all character types), and \\x85 as a line separator for wide characters / Unicode only. 200* Added a new format flag format_literal that treats the replace string as a literal, rather than a Perl or Sed style format string. 201* 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 occurred. 202 203[h4 Boost 1.32.1] 204 205* Fixed bug in partial matches of bounded repeats of '.'. 206 207[h4 Boost 1.31.0] 208 209* Completely rewritten pattern matching code - it is now up to 10 times faster than before. 210* Reorganized documentation. 211* Deprecated all interfaces that are not part of the regular expression standardization proposal. 212* Added regex_iterator and regex_token_iterator . 213* Added support for Perl style independent sub-expressions. 214* 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. 215* Added experimental support for extended capture information. 216* 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. 217 218[endsect] 219 220 221 222
