h1. Changelog

Here's a summary of changes in each release. The list doesn't include some small changes or updates to test cases.

h2. Version 3.5.6 - upcoming

h2. "Version 3.5.5 - 2014/01/02":https://github.com/textile/php-textile/releases/tag/v3.5.5

* Fix rendering of left and right image alignment in non-lite restricted mode (closes "#132":https://github.com/textile/php-textile/issues/132).
* Fix wrong triggered error type when using the deprecated @$encode@ option of @Parser::textileThis()@.
* Fix attribute regular expression to stop it matching multiple times (closes "#131":https://github.com/textile/php-textile/issues/131).
* Fix rendering of lists in table cells with span attributes set (closes "#135":https://github.com/textile/php-textile/issues/135).
* Throws an exception if @Parser::__construct()@ is given invalid document type, instead of eating it silently and returning document using the default content-type you weren't wishing for. Prevents issues where you want HTML5, but silently got XHTML due to typo or an issue in application design.
* Clean user-supplied styles prior to sorting and re-formatting.
* Remove dead code and duplicated procedures as outlined by code coverage reports.
* Remove unused internal method @Parser::fSpecial()@.
* Test code coverage, coding style and run unit tests against "HHVM":http://hhvm.com.
* Footnote reference numbers support unicode characters.
* Use named sub-patterns in regular expressions (closes "#121":https://github.com/textile/php-textile/issues/121).
* Refactored link detection code.

h2. "Version 3.5.4 - 2013/11/06":https://github.com/textile/php-textile/releases/tag/v3.5.4

* Fix broken image alignment in HTML5 mode (closes "#123":https://github.com/textile/php-textile/issues/123).
* Fix duplicate HTML IDs that occur when a footnote isn't referenced in the content (closes "#125":https://github.com/textile/php-textile/issues/125). 
* Don't include image alignment to the URL in restricted mode.
* Detect and process quoted quote symbols.
* New link parser (closes "#86":https://github.com/textile/php-textile/issues/86, "#87":https://github.com/textile/php-textile/issues/87 and "#128":https://github.com/textile/php-textile/issues/128).

h2. "Version 3.5.3 - 2013/10/30":https://github.com/textile/php-textile/releases/tag/v3.5.3

* Fix URL reference token spoofing.
* Fix broken parser output when $strict argument was set to TRUE (closes "#119":https://github.com/textile/php-textile/issues/119).
* Fix memory leaking tag cache. Tag cache is never reset between @textileThis()@ and @textileRestricted()@ calls referencing the same instance.
* Fix rare instances where a link displays a wrong URL mentioned elsewhere in the document.
* Fix invalid markup generated when Redcloth-style definition list is used inside a table cell.
* Link aliases follow same allowed URL schemes as normal links.
* Update @hasRawText()@ and @fPBr()@ to detect a wider range of raw HTML and XHTML.

h2. "Version 3.5.2 - 2013/10/25":https://github.com/textile/php-textile/releases/tag/v3.5.2

* Improved support for Redcloth-style definition lists.
*# Allow multiple terms
*# Allow linebreaks in terms
* Fix incorrectly rendered @rel@ attributes (closes "#103":https://github.com/textile/php-textile/issues/103).
* Fix @getSymbol()@ so it actually returns the named symbol (closes "#104":https://github.com/textile/php-textile/issues/104).
* Fix unicode link aliases that were broken on some PCRE_UTF8 supporting systems.
* Fix collapsing whitespace and preserve newlines. Preserves whitespace inside long @bc@, @notextile@ and @pre@ blocks, rather than collapsing two or more empty lines down to one. Renders whitespace as it was defined, rather than using hard-coded single LF to separate lines (closes "#109":https://github.com/textile/php-textile/issues/109 and "#111":https://github.com/textile/php-textile/pull/111).
* Fix the number of code tags rendered inside long code blocks (closes "#116":https://github.com/textile/php-textile/issues/116).
* Fix token spoofing from the document body by randomizing token references (closes "#115":https://github.com/textile/php-textile/issues/115).
* Add image dimensions to images even when Textile is run on command line. On CLI, images are looked from the current working directory.
* Define internal class properties as protected rather than at all, causing them to be created as public.
* Move internal property definitions from the constructor to class definition.
* Added runnable PHPUnit tests, integration with "Travis CI":https://travis-ci.org/.
* Removed error suppression, the code doesn't intentionally produce notices.
* Add @br@ tags to headings instead of leaving linebreaks untouched.

h2. "Version 3.5.1 - 2013/01/01":https://github.com/textile/php-textile/releases/tag/v3.5.1

* Remove horizontal alignment from inline elements (closes "#66":https://github.com/textile/php-textile/issues/66).
* Reinstate automatic generation of image width and height generation for relative images (closes "#101":https://github.com/textile/php-textile/issues/101).

* Allow "." in class attributes (closes "#97":https://github.com/textile/php-textile/issues/97).

h2. "Version 3.5.0 - 2012/12/12":https://github.com/textile/php-textile/releases/tag/v3.5.0

* Add composer.json to allow installation via the "Composer PHP package manager":https://getcomposer.org/.
* Regular expression improvements (issues "#78":https://github.com/textile/php-textile/issues/78, "#81":https://github.com/textile/php-textile/issues/81 and "#83":https://github.com/textile/php-textile/issues/83).

* Fix undefined variable in Redcloth-style definition lists.
* Improvements to image handling (closes "#69":https://github.com/textile/php-textile/issues/69).
* Extend recognition of dimension sign to more complex cases. Eg...
*# @-0.5 x -.1 x +100@ => %-0.5 × -.1 × +100%
*# @10 x -€ 110,00@ => %10 × -€ 110,00% (this replacement is available only if unicode support is included in your PCRE implementation and any character that is a currency symbol should work)
* Change parse tokens to further prevent glyphs from matching them internally.
* Improve handling of textile within table cells without leading or trailing spaces (eg. @|"$":https://github.com"|_Here we are_|==code==|@ etc).
* Improve handling of lists within table cells. (closes "#79":https://github.com/textile/php-textile/issues/79)
* Allow mixed nested lists (Already supported in Redcloth).
* Improve detection of open quotes in situations like @["(Berk). Hilton"]@ (where the open quote was previously was incorrectly detected encoded).
* Fix a problem with links followed by ':', ';' or '?' like @Do you like "cheese":/cheese?@ where the '?' becomes part of the href rather than a '?' at the end of the sentence. This happens on platforms where PCRE has unicode support.
* Removal of leading \t from generated paragraphs & better indentation of generated lists in the HTML (closes "#90":https://github.com/textile/php-textile/issues/90).
* New method @textileEncode()@. This is preferred to calling @textileThis()@ with the $encode flag.
* "PSR-0, PSR-1 & PSR-2":https://github.com/php-fig/fig-standards/tree/master/accepted conformity added.
*# Split class Textile into classes @Parser@, @DataBag@ & @Tag@ and moved them into @src/textile/php-textile@ directory for PSR-0.
*# Unified method names & coding styles according to PSR-1 & PSR-2.
*# Switched from using defines to explicit set methods; @setSymbol()@ & @setRelativeImagePrefix()@.

* Support international format @tel@ URIs via linkrefs (link aliases).
* Extend linkrefs to all available URI schemes in unrestricted mode.
* Reverted looser matching of list-like structures as it introduced problems in block-level elements that
  can legitimately have literals or other non-lists in them that are similar to textile's lists.
  See issue "#65"::https://github.com/textile/php-textile/issues/65 for some examples.
* Fixed "#61"::https://github.com/textile/php-textile/issues/61 which caused strong numeric strings at the start of a line to be turned into lists.
* Reverted auto-breaking in table cells as it introduced "#71"::https://github.com/textile/php-textile/issues/71 (breaking lists within table cells).
* Fixed "#67"::https://github.com/textile/php-textile/issues/67 which ran textile within table cells through the glyph routine twice.
