|
||||
* [*Breaking change]: empty expressions, and empty alternatives are now
|
||||
allowed when using the Perl regular expression syntax. This change has
|
||||
been added for Perl compatibility, when the new [syntax_option_type]
|
||||
['no_empty_expressions] is set then the old behaviour is preserved and
|
||||
empty expressions are prohibited. This is issue
|
||||
[@https://svn.boost.org/trac/boost/ticket/1081 #1081].
|
||||
* Added support for Perl style ${n} expressions in format strings
|
||||
(issue [@https://svn.boost.org/trac/boost/ticket/2556 #2556]).
|
||||
* Added support for accessing the location of sub-expressions within the
|
||||
regular expression string
|
||||
(issue [@https://svn.boost.org/trac/boost/ticket/2269 #2269]).
|
||||
* Fixed compiler compatibility issues
|
||||
[@https://svn.boost.org/trac/boost/ticket/2244 #2244],
|
||||
[@https://svn.boost.org/trac/boost/ticket/2514 #2514],
