'Supage Fun' Changelog:
 =======================

* (trunk) -- Version 0.5.3:
  - With parameter 'linked' set, wfEscapeWikiText() won't be used to escape sitenames within links since this could break a link.

* December 2, 2011 -- Version 0.5.2:
  - Support for 'Parser Fun' extensions 'THIS' function added. With 'Parser Fun' enabled it now is possible to call
    '{{THIS:SUBPAGETITLE}}' which will output the subpage title of the template or page where the phrase is defined on, not the
    page which is actually being rendered by the parser as '{{SUBPAGETITLE}}' would output it.
  - Parser function functions within 'ExtSubpageFun' class now have a 'pf_' prefix.

* November 8, 2011 -- Version 0.5.1:
  - All functions/variables returning page names in any way are using 'wfEscapeWikiText()' now like other variables like 'PAGENAME'
    for example.
  - 'filter' parameter can be used for 'NUMBEROFSUBPAGES'.

* November 7, 2011 -- Version 0.5:
  - All magic words are case-sensitive now and must be written in UPPERCASE.
  - Input of invalid page names (with forbidden characters) will output '' instead of raising a php error. This behavior is adopted
    from {{FULLPAGENAME}} which also outputs '' in that case.
  - New parameter 'filter' for 'SUBPAGES', 'PARENTPAGES' and 'SIBLINGPAGES'. This allows to filter the list of pages by keywords or
    a regular expression (delimiters '/', '%' and '|' allowed, flags 'imsSuUx'. If the string is not considered a valid regex, the
    string is considered a list of keywords (separated by '|' e.g. through a template '{{!}}').
  - Functions output on category pages with link parameter set will no longer create category links but real links how it should be.
  - Language file added.
  - 'SubpageInfo' class put into new file 'SFun_SubpageInfo.php'.
  - Further code cleanup. Magic words overload removed.
  - 'Supage Fun' now is distributed under ISC License and can be found in wikimedia.org svn.


* September 16, 2011 -- Version 0.4:
  - Cleaned-up code, gotten rid of global functions. All useful functions for other extension developers are in 'SubpageInfo' class,
    parser function/variables stuff has its own 'ExtSubpageFun' class now.
  - Function 'NUMBEROFSUBPAGES' now allows the use of parameter 'depth'.
  - Function 'PARENTPAGES' now allows negative 'depth' values to return that many pages starting from the top-level parent.
  - If parameter 'depth' is '0', 'NUMBEROFSUBPAGES' will return '0', 'PARENTPAGES' and 'SUBPAGETITLE' an empty string.
  - Named function Arguments won't accidentally be threated as parameter '1' anymore if no value is given. E.g. '{{PARENTPAGES:depth=}}'
    is possible without confusion now.


* March 24, 2011 -- Version 0.3.2.1:
  - Fit for PHP 5.3: [http://php.net/manual/en/function.split.php Split] function replaced with
    [http://www.php.net/manual/en/function.preg-split.php preg_split].

* March 24, 2011 -- Version 0.3.2:
  - 'SUBPAGETITLE' won't output any namespace anymore, just the main part.
  - Bug solved in which page titles with some special characters were causing problems.

* December 30, 2009 -- Version 0.3.1:
  - Minor change in extension meta infos for proper appearance in [[special:version]].
  - Extension status is ''stable'' now.

* December 10, 2009 -- Version 0.3.0:
  - Changed parameters '2' and '3' for advanced list formations against named parameters 'linked' and 'sep'.
  - Added named parameter 'depth' for 'SUBPAGES' and 'PARENTPAGES'.
