  18 [h4 Boost.Regex-5.1.2 (Boost-1.62.0)]
  19
  20
  21 * Fix buffer over-run error when parsing certain invalid regexes, see [@https://svn.boost.org/trac/boost/ticket/12222 #12222].
  22 * Fix detection of ICU in library build, see [@https://svn.boost.org/trac/boost/ticket/12152 #12152].
  23 * Fix bug in case sensitivity change, see [@https://svn.boost.org/trac/boost/ticket/11940 #11940].
  24 * Allow types wider than int in `\x{}` expressions (for char32_t etc), see [@https://svn.boost.org/trac/boost/ticket/11988 #11988].
  25
  26 [h4 Boost.Regex-5.1.1 (Boost-1.61.0)]
  27
  28 * Change to lockfree implementation of memory cache, see [@https://github.com/boostorg/regex/pull/23 PR#23].
  29
  30 [h4 Boost.Regex-5.1.0 (Boost-1.60.0)]
  31
  32 * Add support for Perl's backtracking control verbs, see [@https://svn.boost.org/trac/boost/ticket/11205 #11205].  Note however, that
  33 (*MARK) and operations on marks are not currently supported.
  34 * Fix incorrect range end when matching \[\[:unicode:\]\], see [@https://svn.boost.org/trac/boost/ticket/11524 #11524].
  35 * Change POSIX reg_comp API to not check potentially uninitialized memory, note that code which was previously free from memory
  36 leaks (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].
  37 * Make sub_match a valid C++ range type, see [@https://svn.boost.org/trac/boost/ticket/11036 #11036].
  38
  39 [h4 Boost.Regex-5.0.1 (Boost-1.58.0)]
  40
  41 * Fixed some typos as in [@https://svn.boost.org/trac/boost/ticket/10682 #10682].
  42 * Merged [@https://github.com/boostorg/regex/pull/6 pull-request #6] for Coverity warnings.
  43 * Merged [@https://github.com/boostorg/regex/pull/7 pull-request #7] for Coverity warnings.
  44 * Merged [@https://github.com/boostorg/regex/pull/8 pull-request #8] for Coverity warnings.
  45 * Merged [@https://github.com/boostorg/regex/pull/10 pull-request #10] to enable more build variants when linking to ICU.
  46 * Fix issue with ICU and partial matches, see [@https://svn.boost.org/trac/boost/ticket/10114 #10114].
  47 * Removed delayload support for the ICU libraries: this doesn't work with the latest ICU releases (linker errors).
  48
  49
  50 [h4 Boost.Regex-5.0.0 (Boost-1.56.0)]
  51
  52 * Moved to library-specific version number post the move to Git.  And since we have one (minor) breaking change
  53 this gets bumped up from v4 to v5.
  54 * [*Breaking change:] corrected behavior of `basic_regex<>::mark_count()` to match existing documentation,
  55 `basic_regex<>::subexpression(n)` changed to match, see [@https://svn.boost.org/trac/boost/ticket/9227 #9227]
  56 * Fixed issue [@https://svn.boost.org/trac/boost/ticket/8903 #8903].
  57 * Fixed documentation typos from [@https://svn.boost.org/trac/boost/ticket/9283 #9283].
  58 * Fixed bug in collation code that failed if the locale generated collation strings with embedded nul's,
  59 see [@https://svn.boost.org/trac/boost/ticket/9451 #9451].
  60 * Apply patch for unusual thread usage (no statically initialized mutexes), see [@https://svn.boost.org/trac/boost/ticket/9461 #9461].
  61 * Added better checks for invalid UTF-8 sequences, see [@https://svn.boost.org/trac/boost/ticket/9473 #9473].

 111
 112 [h4 Boost 1.42]
 113
 114 * Added support for Functors rather than strings as format expressions.
 115 * Improved error reporting when throwing exceptions to include better more relevant information.
 116 * Improved performance and reduced stack usage of recursive expressions.
 117 * Fixed tickets
 118 [@https://svn.boost.org/trac/boost/ticket/2802 #2802],

 128
 129 [h4 Boost 1.40]
 130
 131 * Added support for many Perl 5.10 syntax elements including named
 132 sub-expressions, branch resets and recursive regular expressions.
 133
 134 [h4 Boost 1.38]
 135
 136 * [*Breaking change]: empty expressions, and empty alternatives are now
 137 allowed when using the Perl regular expression syntax.  This change has
 138 been added for Perl compatibility, when the new [syntax_option_type]
 139 ['no_empty_expressions] is set then the old behaviour is preserved and
 140 empty expressions are prohibited.  This is issue
 141 [@https://svn.boost.org/trac/boost/ticket/1081 #1081].
 142 * Added support for Perl style ${n} expressions in format strings
 143 (issue [@https://svn.boost.org/trac/boost/ticket/2556 #2556]).
 144 * Added support for accessing the location of sub-expressions within the
 145 regular expression string
 146 (issue [@https://svn.boost.org/trac/boost/ticket/2269 #2269]).
 147 * Fixed compiler compatibility issues
 148 [@https://svn.boost.org/trac/boost/ticket/2244 #2244],
 149 [@https://svn.boost.org/trac/boost/ticket/2514 #2514],
 150 and
 151 [@https://svn.boost.org/trac/boost/ticket/2244 #2458].
 152
 153
 154 [h4 Boost 1.34]
 155
 156 * Fix for non-greedy repeats and partial matches not working correctly in some cases.
 157 * Fix for non-greedy repeats on VC++ not working in some cases (bug report 1515830).
 158 * Changed match_results::position() to return a valid result when *this represents a partial match.
 159 * Fixed the grep and egrep options so that the newline character gets treated the same as |.
 160
 161 [h4 Boost 1.33.1]
 162
 163 * Fixed broken makefiles.
 164 * Fixed configuration setup to allow building with VC7.1 - STLport-4.6.2 when using /Zc:wchar_t.
 165 * Moved declarations class-inline in static_mutex.hpp so that SGI Irix compiler can cope.
 166 * Added needed standard library #includes to fileiter.hpp, regex_workaround.hpp and cpp_regex_traits.hpp.
 167 * Fixed a bug where non-greedy repeats could in certain strange circumstances repeat more times than their maximum value.
 168 * Fixed the value returned by basic_regex<>::empty() from a default constructed object.
 169 * Changed the definition of regex_error to make it backwards compatible with Boost-1.32.0.
 170 * Disabled external templates for Intel C++ 8.0 and earlier - otherwise unresolved references can occur.
 171 * 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.
 172 * Initialise all the data members of the unicode_iterators: this keeps gcc from issuing needless warnings.
 173 * Ported the ICU integration code to VC6 and VC7.
 174 * Ensured code is STLport debug mode clean.
 175 * 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).
 176 * Fixed strange bug with non-greedy repeats inside forward lookahead assertions.
 177 * Enabled negated character classes inside character sets.
 178 * Fixed regression so that [a-z-] is a valid expression again.
 179 * Fixed bug that allowed some invalid expressions to be accepted.
 180
 181 [h4 Boost 1.33.0]
 182
 183 * Completely rewritten expression parsing code, and traits class support; now conforms to the standardization proposal.
 184 * 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.
 185 * Breaking Change: POSIX-extended and POSIX-basic regular expressions now enforce the letter of the POSIX standard much more closely than before.
 186 * Added support for (?imsx-imsx) constructs.
 187 * Added support for lookbehind expressions (?<=positive-lookbehind) and (?<!negative-lookbehind).
 188 * Added support for conditional expressions (?(assertion)true-expression|false-expression).
 189 * Added MFC/ATL string wrappers.
 190 * Added Unicode support; based on ICU.
 191 * Changed newline support to recognise \\f as a line separator (all character types), and \\x85 as a line separator for wide characters / Unicode only.
 192 * Added a new format flag format_literal that treats the replace string as a literal, rather than a Perl or Sed style format string.
 193 * 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.
 194
 195 [h4 Boost 1.32.1]
 196
 197 * Fixed bug in partial matches of bounded repeats of '.'.
 198
 199 [h4 Boost 1.31.0]
 200
 201 * Completely rewritten pattern matching code - it is now up to 10 times faster than before.
 202 * Reorganized documentation.
 203 * Deprecated all interfaces that are not part of the regular expression standardization proposal.
 204 * Added regex_iterator and regex_token_iterator .
 205 * Added support for Perl style independent sub-expressions.
 206 * 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.
 207 * Added experimental support for extended capture information.
 208 * 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.
