Version 3.5.0

  • Avoid mutating the options hash passed to a render object.

    Refs #663.

    Max Schwenk

  • Fix a segfault rendering quotes using StripDown and the :quote option.

    Fixes #639.

  • Fix warning: instance variable @options not initialized when running under verbose mode (-w, $VERBOSE = true).

  • Fix SmartyPants single quotes right after a link. For example:

    [John](http://john.doe)'s cat

    Will now properly converts ' to a right single quote (i.e. ).

    Fixes #624.

  • Remove the rel and rev attributes from the output generated for footnotes as they don't pass the HTML 5 validation.

    Fixes #536.

  • Automatically enable the fenced_code_blocks option passing a HTML_TOC object to the Markdown object's constructor since some languages rely on the sharp to comment code.

    Fixes #451.

  • Allow passing Range objects to the nesting_level option to have a higher level of customization for table of contents: 2..5)

    Fixes #519.

Version 3.4.0

  • Rely on djb2 hashing generating anchors with non-ASCII chars.

    Fix issue #538.

    Alexey Kopytko, namusyaka

  • Added suppport for HTML 5 details and summary tags.

    Fix issue #578.

    James Edwards-Jones

  • Multiple single quote pairs are parsed correctly with SmartyPants.

    Fix issue #549.

    Jan Jędrychowski

  • Table headers don't require a minimum of three dashes anymore; a single one can be used for each row.

  • Remove escaped entities from HTML render table of contents' ids to be consistent with the HTML_TOC render.

    Fix issue #529.

  • Remove periods at the end of URLs when autolinking to make sure that links at the end of a sentence get properly generated.

    Fix issue #465.

  • Expose the Markdown and rendering options through a Hash inside the @options instance variable for custom render objects.

  • Avoid escaping ampersands in href links.

    Nolan Evans

Version 3.3.4

  • Fix bufprintf to correctly work on Windows MinGW-w64 so strings are properly written to the buffer.

    Kenichi Saita

  • Fix the header anchor normalization by skipping non-ASCII chars and not calling tolower because this leads to invalid UTF-8 byte sequences in the HTML output. (tolower is not locale-aware)

    Clemens Gruber

Version 3.3.3

  • Fix a memory leak instantiating a Redcarpet::Render::Base object.

    Oleg Dashevskii

  • Fix the StripDown renderer to handle the :highlight option.

    Itay Grudev

  • The StripDown renderer handles tables if the tables extension is enabled.


  • Fix Smarty Pants to avoid fraction conversions when there are several numbers separated with slashes (e.g. for a date).

    Sam Saffron

Version 3.3.2

  • Fix a potential security issue in the HTML renderer (Thanks to Giancarlo Canales Barreto for the heads up)

Version 3.3.1

  • Include the Redcarpet::CLI's file in the gemspec to make it available when downloading.

Version 3.3.0

  • Fix the stripping of surrounding characters that should be removed during anchor generation.

  • Provide a Redcarpet::CLI class to create custom binary files.

    Relying on Ruby's OptionParser, it's now straightforward to add new options, rely on custom render objects or handle differently the rendering of the provided files.

  • Undeprecate the compatibility layer for the old RedCloth API.

    This layer actually ease the support of libraries supporting different Markdown processors.

  • Strip out style tags at the HTML-block rendering level when the :no_styles options is enabled ; previously they were only removed inside paragraphs.

  • Avoid parsing images when the given URL isn't safe and the :safe_links_only option is enabled.

    Alex Serban

  • Avoid parsing references inside fenced code blocks so they are now kept in the code snippet.

    David Waller

  • Avoid escaping table-of-contents' headers by default. A new :escape_html option is now available for the HTML_TOC object if there are security concerns.

  • Add the lang- prefix in front of the language's name when using :prettify along with :fenced_code_blocks.

  • Non-alphanumeric chars are now stripped out from generated anchors (along the lines of Active Support's #parameterize method).

Version 3.2.3

  • Avoid rewinding content of a previous inline when autolinking is enabled.

    Daniel LeCheminant

  • Fix escaping of forward slashes with the Safe render object (add a missing semi-colon).

Version 3.2.2

  • Consider script as a block-level element so it doesn't get included inside a paragraph.

Version 3.2.1

  • Load RedcarpetCompat when requiring Redcarpet for the sake of backward compatibility.

    Loren Segal

Version 3.2.0

  • Add a Safe renderer to deal with users' input. The escape_html and safe_links_only options are turned on by default.

    Moreover, the block_code callback removes the tag's class since the user can basically set anything with the vanilla one.

    Robin Dupret

  • HTML5 block-level tags are now recognized


  • The StripDown render object now displays the URL of links along with the text.

    Robin Dupret

  • The RedCloth API compatibility layer is now deprecated.

    Robin Dupret

  • A hyphen and an equal should not be converted to heading.


  • Fix emphasis character escape sequence detection while mid-emphasis.


  • Add = to the whitelist of escaped chars so it can be used inside highlighted snippets.


  • Convert trailing single quotes to curly quotes. For example, Road Trippin' now converts to Road Trippin’.

    Kevin Chen

  • Allow in-page links (e.g. [headline](#headline)) when :safe_links_only is set.


  • Enable emphasis inside of sentences in multi-byte languages when :no_intra_emphasis is set.

    Chun-wei Kuo

  • Avoid making :no_intra_emphasis only match spaces. This allows using emphasizes inside quotes when the option is enabled for instance.

    Jason Webb and BJ Homer

  • The StripDown renderer handles image tags now.

Version 3.1.2

  • Remove the yielding of anchors in the header callback. This was a breaking change between 3.0 and 3.1 as the method's arity changed.

Version 3.1.1

  • Fix a segfault when parsing text with headers.

Version 3.1.0

  • Yield the anchor of the headers

    Using the header callback, it's now possible to get access to the humanized generated id to easily keep tracking of the tree of headers or simply handle the duplicate values easily.

    Since the HTML_TOC and HTML objects both have this callback, it's advisable to define a module and mix it in these objects to avoid code duplication.

    Robin Dupret

  • Allow using tabs between a reference's colon and its link

    Fix issue #337

    Juan Guerrero

  • Make ordered lists preceded by paragraph parsed with :lax_spacing

    Previously, enabling the :lax_spacing option, if a paragraph was followed by an ordered list it was unparsed and was part of the paragraph but this is no more the case.

    Robin Dupret

  • Feed the gemspec into ExtensionTask so that we can pre-compile. ie. rake native gem

    Todd Edwards

  • Revert lax indent of less than 4 characters after list items

    Follow the standard to detect when new paragraph is outside last item. Fixes issue #111.

    Eric Bréchemier

  • Fix code blocks' classes when using Google code prettify

    When using the the :prettify option and specifying the language name, the generated code block's class had a missing space.


  • Add -v/--version and -h flags to commandline redcarpet

    Lukas Stabe

  • Add optional quote support through the :quote option. Render quotations marks to q HTML tag.

    This is a "quote".

    Anatol Broder

  • Ensure inline markup in titles is correctly stripped when generating headers' anchor.

    Robin Dupret

  • Revert the unescaping behavior on comments

    This behavior doesn't follow the conformance suite.

    Robin Dupret

  • Add optional footnotes support

    Add PHP-Markdown style footnotes through the :footnotes option.

    Ben Dolman, Adam Florin, microjo, brief

  • Enable GitHub style anchors for headers

    Passing the with_toc_data option to a HTML render object now generates GitHub style anchors.

    Matt Rogers

  • Allow to set a maximum rendering level for HTML_TOC

    Allow the user to pass a nesting_level option when instantiating a new HTML_TOC render object in order to limit the nesting level in the generated table of content. For example: 2))

  • Fix issue #57 Mike Morearty

  • Ensure new lines characters are inserted when using the StripDown render. Robin Dupret

  • Removed and ignored Gemfile.lock Ryan McGeary

  • Added support for org-table syntax Ryan McGeary
