Subject: Switch docs to MKDocs (#602)

Fixes #601. Merged in 6f87b32 from the md3 branch and did a lot of cleanup.

Changes include:

* Removed old docs build tool, templates, etc.

* Added MkDocs config file, etc.

* filename.txt => filename.md

* pythonhost.org/Markdown => Python-Markdown.github.io

* Markdown lint and other cleanup.

* Automate pages deployment in makefile with `mkdocs gh-deploy`

    Assumes a git remote is set up named "pages". Do

        git remote add pages https://github.com/Python-Markdown/Python-Markdown.github.io.git

    ... before running `make deploy` the first time.

+title: Release Notes for v2.0
+
+Python-Markdown 2.0 Release Notes
+=================================
+
+We are happy to release Python-Markdown 2.0, which has been over a year in the
+making. We have rewritten significant portions of the code, dramatically
+extending the extension API, increased performance, and added numerous
+extensions to the distribution (including an extension that mimics PHP Markdown
+Extra), all while maintaining backward compatibility with the end user API in
+version 1.7.
+
+Python-Markdown supports Python versions 2.3, 2.4, 2.5, and 2.6. We have even
+released a version converted to Python 3.0!
+
+Backwards-incompatible Changes
+------------------------------
+
+While Python-Markdown has experienced numerous internal changes, those changes
+should only affect extension authors. If you have not written your own
+extensions, then you should not need to make any changes to your code.
+However, you may want to ensure that any third party extensions you are using
+are compatible with the new API.
+
+The new extension API is fully [documented](../extensions/api.md) in the docs.
+Below is a summary of the significant changes:
+
+* The old home-grown NanoDOM has been replaced with ElementTree. Therefore all
+  extensions must use ElementTree rather than the old NanoDOM.
+* The various processors and patterns are now stored with OrderedDicts rather
+  than lists. Any code adding processors and/or patterns into Python-Markdown
+  will need to be adjusted to use the new API using OrderedDicts.
+* The various types of processors available have been either combined, added,
+  or removed. Ensure that your processors match the currently supported types.
+
+What's New in Python-Markdown 2.0
+---------------------------------
+
+Thanks to the work of Artem Yunusov as part of GSoC 2008, Python-Markdown uses
+ElementTree internally to build the (X)HTML document from markdown source text.
+This has resolved various issues with the older home-grown NanoDOM and made
+notable increases in performance.
+
+Artem also refactored the Inline Patterns to better support nested patterns
+which has resolved many inconsistencies in Python-Markdown's parsing of the
+markdown syntax.
+
+The core parser had been completely rewritten, increasing performance and, for
+the first time, making it possible to override/add/change the way block level
+content is parsed.
+
+Python-Markdown now parses markdown source text more closely to the other
+popular implementations (Perl, PHP, etc.) than it ever has before. With the
+exception of a few minor insignificant differences, any difference should be
+considered a bug, rather than a limitation of the parser.
+
+The option to return HTML4 output as apposed to XHTML has been added. In
+addition, extensions should be able to easily add additional output formats.
+
+As part of implementing markdown in the Dr. Project project (a Trac fork), among
+other things, David Wolever refactored the "extension" keyword so that it
+accepts either the extension names as strings or instances of extensions. This
+makes it possible to include multiple extensions in a single module.
+
+Numerous extensions are included in the distribution by default. See
+[available_extensions](../extensions/index.md) for a complete list.
+
+See the [Change Log](index.md) for a full list of changes.

+title: Release Notes for v2.1
+
+Python-Markdown 2.1 Release Notes
+=================================
+
+We are pleased to release Python-Markdown 2.1 which makes many
+improvements on 2.0. In fact, we consider 2.1 to be what 2.0 should have been.
+While 2.1 consists mostly of bug fixes, bringing Python-Markdown more inline
+with other implementations, some internal improvements were made to the parser,
+a few new built-in extensions were added, and HTML5 support was added.
+
+Python-Markdown supports Python versions 2.4, 2.5, 2.6, 2.7, 3.1, and 3.2 out
+of the box. In fact, the same code base installs on Python 3.1 and 3.2 with no
+extra work by the end user.
+
+Backwards-incompatible Changes
+------------------------------
+
+While Python-Markdown has received only minor internal changes since the last
+release, there are a few backward-incompatible changes to note:
+
+* Support had been dropped for Python 2.3. No guarantees are made that the
+  library will work in any version of Python lower than 2.4. Additionally, while
+  the library had been tested with Python 2.4, consider Python 2.4 support to be
+  depreciated. It is not likely that any future versions will continue to
+  support any version of Python less than 2.5. Note that Python 3.0 is not
+  supported due to a bug in its 2to3 tool. If you must use Python-Markdown with
+  Python 3.0, it is suggested you manually use Python 3.1's 2to3 tool to do a
+  conversion.
+
+* Python-Markdown previously accepted positional arguments on its class and
+  wrapper methods. It now expects keyword arguments. Currently, the positional
+  arguments should continue to work, but the solution feels hacky and may be
+  removed in a future version. All users are encouraged to use keyword arguments
+  as documented in the [Library Reference](../reference.md).
+
+* Past versions of Python-Markdown provided module level Global variables which
+  controlled the behavior of a few different aspects of the parser. Those global
+  variables have been replaced with attributes on the Markdown class.
+  Additionally, those attributes are settable as keyword arguments when
+  initializing a class instance. Therefore, if you were editing the global
+  variables (either by editing the source or by overriding them in your code),
+  you should now set them on the class. See the [Library
+  Reference](../reference.md) for the options available.
+
+* If you have been using the [HeaderId](../extensions/header_id.md) extension to
+  define custom ids on headers, you will want to switch to using the new
+  [Attribute List](../extensions/attr_list.md) extension. The HeaderId extension
+  now only auto-generates ids on headers which have not already had ids defined.
+  Note that the [Extra](../extensions/extra.md) extension has been switched to
+  use Attribute Lists instead of HeaderId as it did previously.
+
+* Some code was moved into the `markdown.util` namespace which was previously in
+  the `markdown` namespace. Extension authors may need to adjust a few import
+  statements in their extensions to work with the changes.
+
+* The command line script name was changed to `markdown_py`. The previous name
+  (`markdown`) was conflicting with people (and Linux package systems) who also
+  had markdown.pl installed on there system as markdown.pl's command line script
+  was also named `markdown`. Be aware that installing Python-Markdown 2.1 will
+  not remove the old versions of the script with different names. You may want
+  to remove them yourself as they are unlikely to work properly.
+
+What's New in Python-Markdown 2.1
+---------------------------------
+
+Three new extensions were added. [Attribute Lists](../extensions/attr_list.md),
+which was inspired by Maruku's feature of the same name,
+[Newline to Break](../extensions/nl2br.md), which was inspired by GitHub
+Flavored Markdown, and [Smart Strong](../extensions/smart_strong.md), which
+fills a hole in the Extra extension.
+
+HTML5 is now supported. All this really means is that new block level elements
+introduced in the HTML5 spec are now properly recognized as raw HTML. As
+valid  HTML5 can consist of either HTML4 or XHTML1, there is no need to add a
+new HTML5  serializers. That said, `html5` and `xhtml5` have been added as
+aliases of the `html4` and `xhtml1` serializers respectively.
+
+An XHTML serializer has been added. Previously, ElementTree's XML serializer
+was being used for XHTML output. With the new serializer we are able to avoid
+more invalid output like empty elements (i.e., `<p />`) which can choke
+browsers.
+
+Improved support for Python 3.x. Now when running `setupy.py install` in
+Python 3.1 or greater the 2to3 tool is run automatically. Note that Python 3.0
+is not supported due to a bug in its 2to3 tool. If you must use Python-Markdown
+with Python 3.0, it is suggested you manually use Python 3.1's 2to3 tool to
+do a conversion.
+
+Methods on instances of the Markdown class that do not return results can now
+be changed allowing one to do `md.reset().convert(moretext)`.
+
+The Markdown class was refactored so that a subclass could define it's own
+`build_parser` method which would build a completely different parser. In
+other words, one could use the basic machinery in the markdown library to
+build a parser of a different markup language without the overhead of building
+the markdown parser and throwing it away.
+
+Import statements within markdown have been improved so that third party
+libraries can embed the markdown library if they desire (licensing permitting).
+
+Added support for Python's `-m` command line option. You can run the markdown
+package as a command line script. Do `python -m markdown [options] [args]`.
+Note that this is only fully supported in Python 2.7+. Python 2.5 & 2.6
+require you to call the module directly (`markdown.__main__`) rather than
+the package (`markdown`). This does not work in Python 2.4.
+
+The command line script has been renamed to `markdown_py` which avoids all the
+various problems we had with previous names.  Also improved the command line
+script to accept input on `stdin`.
+
+The testing framework has been completely rebuilt using the Nose testing
+framework. This provides a number of benefits including the ability to better
+test the built-in extensions and other options available to change the parsing
+behavior. See the [Test Suite](../test_suite.md) documentation for details.
+
+Various bug fixes have been made, which are too numerous to list here. See the
+[commit log](https://github.com/Python-Markdown/markdown/commits/master) for a
+complete history of the changes.

+title: Release Notes for v2.2
+
+Python-Markdown 2.2 Release Notes
+=================================
+
+We are pleased to release Python-Markdown 2.2 which makes improvements on 2.1.
+While 2.2 is primarily a bug fix release, some internal improvements were made
+to the parser, and a few security issues were resolved.
+
+Python-Markdown supports Python versions 2.5, 2.6, 2.7, 3.1, and 3.2 out
+of the box.
+
+Backwards-incompatible Changes
+------------------------------
+
+While Python-Markdown has received only minor internal changes since the last
+release, there are a few backward-incompatible changes to note:
+
+* Support had been dropped for Python 2.4. No guarantees are made that the
+  library will work in any version of Python lower than 2.5. Additionally, while
+  the library had been tested with Python 2.5, consider Python 2.5 support to be
+  depreciated. It is not likely that any future versions will continue to
+  support any version of Python less than 2.6.
+
+* For many years Python-Markdown has identified `<ins>` and `<del>` tags in raw
+  HTML input as block level tags. As they are actually inline level tags, this
+  behavior has been changed. This may result in slightly different output. While
+  in most cases, the new output is more correct, there may be a few edge cases
+  where a document author has relied on the previous incorrect behavior. It is
+  likely that a few adjustments may need to be made to those documents.
+
+* The behavior of the `enable_attributes` keyword has been slightly altered. If
+  authors have been using attributes in documents with `safe_mode` on, those
+  attributes will no longer be parsed unless `enable_attributes` is explicitly
+  set to `True`. This change was made to prevent untrusted authors from
+  injecting potentially harmful JavaScript in documents. This change had no
+  effect when not in `safe_mode`.
+
+What's New in Python-Markdown 2.2
+---------------------------------
+
+The docs were refactored and can now be found at
+<http://packages.python.org/Markdown/>. The docs are now maintained in the
+Repository and are generated by the `setup.py build_docs` command.
+
+The [Sane_Lists](../extensions/sane_lists.md)
+extension was added. The Sane Lists Extension alters the behavior of the
+Markdown List syntax to be less surprising by not allowing the mixing of list
+types. In other words, an ordered list will not continue when an unordered list
+item is encountered and vice versa.
+
+Markdown now excepts a full path to an extension module. In other words, your
+extensions no longer need to be in the primary namespace (and start with `mdx_`)
+for Markdown to find them. Just do `Markdown(extension=['path.to.some.module'])`.
+As long as the provided module contains a compatible extension, the extension
+will be loaded.
+
+The BlockParser API was slightly altered to allow `blockprocessor.run` to return
+`True` or `False` which provides more control to the block processor loop from
+within any Blockprocessor instance.
+
+Various bug fixes have been made. See the
+[commit log](https://github.com/Python-Markdown/markdown/commits/master)
+for a complete history of the changes.

+title: Release Notes for v2.3
+
+Python-Markdown 2.3 Release Notes
+=================================
+
+We are pleased to release Python-Markdown 2.3 which adds one new extension,
+removes a few old (obsolete) extensions, and now runs on both Python 2 and
+Python 3 without running the 2to3 conversion tool. See the list of changes
+below for details.
+
+Python-Markdown supports Python versions 2.6, 2.7, 3.1, 3.2, and 3.3.
+
+Backwards-incompatible Changes
+------------------------------
+
+* Support has been dropped for Python 2.5. No guarantees are made that the
+  library will work in any version of Python lower than 2.6. As all supported
+  Python versions include the ElementTree library, Python-Markdown will no
+  longer try to import a third-party installation of ElementTree.
+
+* All classes are now "new-style" classes. In other words, all classes subclass
+  from 'object'. While this is not likely to affect most users, extension
+  authors may need to make a few minor adjustments to their code.
+
+* "safe_mode" has been further restricted. Markdown formatted links must be of a
+  known white-listed scheme when in "safe_mode" or the URL is discarded. The
+  white-listed schemes are: 'HTTP', 'HTTPS', 'FTP', 'FTPS', 'MAILTO', and
+  'news'. Schemeless URLs are also permitted, but are checked in other ways - as
+  they have been for some time.
+
+* The ids assigned to footnotes now contain a dash (`-`) rather than a colon
+  (`:`) when `output_format` it set to `"html5"` or `"xhtml5"`. If you are
+  making reference to those ids in your JavaScript or CSS and using the HTML5
+  output, you will need to update your code accordingly. No changes are
+  necessary if you are outputting XHTML (the default) or HTML4.
+
+* The `force_linenos` configuration setting of the CodeHilite extension has been
+  marked as **Pending Deprecation** and a new setting `linenums` has been added
+  to replace it. See documentation for the [CodeHilite Extension] for an
+  explanation of the new `linenums` setting. The new setting will honor the old
+  `force_linenos` if it is set, but it will raise a `PendingDeprecationWarning`
+  and will likely be removed in a future version of Python-Markdown.
+
+[CodeHilite Extension]: ../extensions/code_hilite.md
+
+* The "RSS" extension has been removed and no longer ships with Python-Markdown.
+  If you would like to continue using the extension (not recommended), it is
+  archived on [GitHub](https://gist.github.com/waylan/4773365).
+
+* The "HTML Tidy" Extension has been removed and no longer ships with
+  Python-Markdown. If you would like to continue using the extension (not
+  recommended), it is archived on
+  [GitHub](https://gist.github.com/waylan/5152650). Note that the underlying
+  library, uTidylib, is not Python 3 compatible. Instead, it is recommended that
+  the newer [PyTidyLib] (version 0.2.2+ for Python 3 comparability - install
+  from GitHub not PyPI) be used. As the API for that library is rather simple,
+  it is recommended that the output of Markdown be wrapped in a call to
+  PyTidyLib rather than using an extension (for example:
+  `tidylib.tidy_fragment(markdown.markdown(source), options={...})`).
+
+[PyTidyLib]: http://countergram.com/open-source/pytidylib
+
+What's New in Python-Markdown 2.3
+---------------------------------
+
+* The entire code base now universally runs in Python 2 and Python 3 without any
+  need for running the 2to3 conversion tool. This not only simplifies testing,
+  but by using Unicode_literals, results in more consistent behavior across
+  Python versions. Additionally, the relative imports (made possible in Python 2
+  via absolute_import) allows the entire library to more easily be embedded in a
+  sub-directory of another project. The various files within the library will
+  still import each other properly even though 'markdown' may not be in Python's
+  root namespace.
+
+* The [Admonition Extension] has been added, which implements [rST-style][rST]
+  admonitions in the Markdown syntax. However, be warned that this extension is
+  experimental and the syntax and behavior is still subject to change. Please
+  try it out and report bugs and/or improvements.
+
+[Admonition Extension]: ../extensions/admonition.md
+[rST]: http://docutils.sourceforge.net/docs/ref/rst/directives.html#specific-admonitions
+
+* Various bug fixes have been made. See the [commit
+  log](https://github.com/Python-Markdown/markdown/commits/master) for a
+  complete history of the changes.

+
+Python-Markdown 2.4 Release Notes
+=================================
+
+We are pleased to release Python-Markdown 2.4 which adds one new extension
+and fixes various bugs. See the list of changes below for details.
+
+Python-Markdown supports Python versions 2.6, 2.7, 3.1, 3.2, and 3.3.
+
+Backwards-incompatible Changes
+------------------------------
+
+* The `force_linenos` configuration setting of the CodeHilite extension has been
+  marked as **Deprecated**. It had previously been marked as "Pending
+  Deprecation" in version 2.3 when a new setting `linenums` was added to replace
+  it. See documentation for the [CodeHilite Extension] for an explanation of the
+  new `linenums` setting. The new setting will honor the old `force_linenos` if
+  it is set, but `force_linenos` will raise a `DeprecationWarning` and will
+  likely be removed in a future version of Python-Markdown.
+
+[CodeHilite Extension]: ../extensions/code_hilite.md
+
+* URLs are no longer percent-encoded. This improves compatibility with the
+  original (written in Perl) Markdown implementation. Please percent-encode your
+  URLs manually when needed.
+
+What's New in Python-Markdown 2.4
+---------------------------------
+
+* Thanks to the hard work of [Dmitry Shachnev] the [Smarty Extension] has been
+  added, which implements [SmartyPants] using Python-Markdown's Extension API.
+  This offers a few benefits over a third party script. The HTML does not need
+  to be "tokenized" twice, no hacks are required to combine SmartyPants and code
+  highlighting, and we get markdown's escaping feature for free. Please try it
+  out and report bugs and/or improvements.
+
+[Dmitry Shachnev]: https://github.com/mitya57
+[Smarty Extension]: ../extensions/smarty.md
+[SmartyPants]: http://daringfireball.net/projects/smartypants/
+
+* The [Table of Contents Extension] now supports new `permalink` option for
+  creating [Sphinx]-style anchor links.
+
+[Table of Contents Extension]: ../extensions/toc.md
+[Sphinx]: http://sphinx-doc.org/
+
+* It is now possible to enable Markdown formatting inside HTML blocks by
+  appending `markdown=1` to opening tag attributes. See [Markdown Inside HTML
+  Blocks] section for details. Thanks to [ryneeverett] for implementing this
+  feature.
+
+[Markdown Inside HTML Blocks]: ../extensions/extra.md#nested-markdown-inside-html-blocks
+[ryneeverett]: https://github.com/ryneeverett
+
+* The code blocks now support emphasizing some of the code lines. To use this
+  feature, specify `hl_lines` option after language name, for example (using the
+  [Fenced Code Extension]):
+
+        ```.python hl_lines="1 3"
+        # This line will be emphasized.
+        # This one won't.
+        # This one will be also emphasized.
+        ```

+    Thanks to [A. Jesse Jiryu Davis] for implementing this feature.
+
+[Fenced Code Extension]: ../extensions/fenced_code_blocks.md

+
+Python-Markdown 2.5 Release Notes
+=================================
+
+We are pleased to release Python-Markdown 2.5 which adds a few new features
+and fixes various bugs. See the list of changes below for details.
+
+Python-Markdown version 2.5 supports Python versions 2.7, 3.2, 3.3, and 3.4.
+
+Backwards-incompatible Changes
+------------------------------
+
+* Python-Markdown no longer supports Python version 2.6. You must be using Python
+  versions 2.7, 3.2, 3.3, or 3.4.
+
+[importlib]: https://pypi.python.org/pypi/importlib
+
+* The `force_linenos` configuration key on the [CodeHilite Extension] has been **deprecated**
+  and will raise a `KeyError` if provided. In the previous release (2.4), it was
+  issuing a `DeprecationWarning`. The [`linenums`][linenums] keyword should be used
+  instead, which provides more control of the output.
+
+[CodeHilite Extension]: ../extensions/code_hilite.md
+[linenums]: ../extensions/code_hilite.md#usage
+
+* Both `safe_mode` and the associated `html_replacement_text` keywords will be
+  deprecated in version 2.6 and will raise a **`PendingDeprecationWarning`** in
+  2.5. The so-called "safe mode" was never actually "safe" which has resulted in
+  many people having a false sense of security when using it. As an alternative,
+  the developers of Python-Markdown recommend that any untrusted content be
+  passed through an HTML sanitizer (like [Bleach]) after being converted to HTML
+  by markdown.
+
+    If your code previously looked like this:
+
+        html = markdown.markdown(text, same_mode=True)
+
+    Then it is recommended that you change your code to read something like this:
+
+        import bleach
+        html = bleach.clean(markdown.markdown(text))
+
+    If you are not interested in sanitizing untrusted text, but simply desire to
+    escape raw HTML, then that can be accomplished through an extension which
+    removes HTML parsing:
+
+        from markdown.extensions import Extension
+
+        class EscapeHtml(Extension):
+            def extendMarkdown(self, md, md_globals):
+                del md.preprocessors['html_block']
+                del md.inlinePatterns['html']
+
+        html = markdown.markdown(text, extensions=[EscapeHtml()])
+
+    As the HTML would not be parsed with the above Extension, then the
+    serializer will escape the raw HTML, which is exactly what happens now when
+    `safe_mode="escape"`.
+
+[Bleach]: https://bleach.readthedocs.io/
+
+* Positional arguments on the `markdown.Markdown()` are pending deprecation as are
+  all except the `text` argument on the `markdown.markdown()` wrapper function.
+  Only keyword arguments should be used. For example, if your code previously
+  looked like this:
+
+         html = markdown.markdown(text, ['extra'])
+
+    Then it is recommended that you change it to read something like this:
+
+        html = markdown.markdown(text, extensions=['extra'])
+
+    !!! Note
+        This change is being made as a result of deprecating `"safe_mode"` as the
+        `safe_mode` argument was one of the positional arguments. When that argument
+        is removed, the two arguments following it will no longer be at the correct
+        position. It is recommended that you always use keywords when they are supported
+        for this reason.
+
+* In previous versions of Python-Markdown, the built-in extensions received
+  special status and did not require the full path to be provided. Additionally,
+  third party extensions whose name started with `"mdx_"` received the same
+  special treatment. This behavior will be deprecated in version 2.6 and will
+  raise a **`PendingDeprecationWarning`** in 2.5. Ensure that you always use the
+  full path to your extensions. For example, if you previously did the
+  following:
+
+        markdown.markdown(text, extensions=['extra'])
+
+    You should change your code to the following:
+
+        markdown.markdown(text, extensions=['markdown.extensions.extra'])
+
+    The same applies to the command line:
+
+        $ python -m markdown -x markdown.extensions.extra input.txt
+
+    See the [documentation](../reference.md#extensions) for a full explanation
+    of the current behavior.
+
+* The previously documented method of appending the extension configuration as
+  a string to the extension name will be deprecated in Python-Markdown
+  version 2.6 and will raise a **`PendingDeprecationWarning`** in 2.5. The
+  [`extension_configs`](../reference.md#extension_configs) keyword should
+  be used instead. See the [documentation](../reference.md#extension-configs)
+  for a full explanation of the current behavior.
+
+What's New in Python-Markdown 2.5
+---------------------------------
+
+* The [Smarty Extension] has had a number of additional configuration settings
+  added, which allows one to define their own substitutions to better support
+  languages other than English. Thanks to [Martin Altmayer] for implementing this
+  feature.
+
+[Smarty Extension]: ../extensions/smarty.md
+[Martin Altmayer]:https://github.com/MartinAltmayer
+
+* Named Extensions (strings passed to the [`extensions`][ex] keyword of
+  `markdown.Markdown`) can now point to any module and/or Class on your
+  PYTHONPATH. While dot notation was previously supported, a module could not
+  be at the root of your PYTHONPATH. The name had to contain at least one dot
+  (requiring it to be a sub-module). This restriction no longer exists.
+
+    Additionally, a Class may be specified in the name. The class must be at the
+    end of the name (which uses dot notation from PYTHONPATH) and be separated
+    by a colon from the module.
+
+    Therefore, if you were to import the class like this:
+
+        from path.to.module import SomeExtensionClass
+
+    Then the named extension would comprise this string:
+
+        "path.to.module:SomeExtensionClass"
+
+    This allows multiple extensions to be implemented within the same module and
+    still accessible when the user is not able to import the extension directly
+    (perhaps from a template filter or the command line).
+
+    This also means that extension modules are no longer required to include the
+    `makeExtension` function which returns an instance of the extension class.
+    However, if the user does not specify the class name (she only provides
+    `"path.to.module"`) the extension will fail to load without the
+    `makeExtension` function included in the module. Extension authors will want
+    to document carefully what is required to load their extensions.
+
+[ex]: ../reference.md#extensions
+
+* The Extension Configuration code has been refactored to make it a little
+  easier for extension authors to work with configuration settings. As a
+  result, the [`extension_configs`][ec] keyword now accepts a dictionary
+  rather than requiring a list of tuples. A list of tuples is still supported
+  so no one needs to change their existing code. This should also simplify the
+  learning curve for new users.
+
+    Extension authors are encouraged to review the new methods available on the
+    `markdown.extnesions.Extension` class for handling configuration and adjust
+    their code going forward. The included extensions provide a model for best
+    practices. See the [API] documentation for a full explanation.
+
+[ec]: ../reference.md#extension_configs
+[API]: ../extensions/api.md#configsettings
+
+* The [Command Line Interface][cli] now accepts a `--extensions_config` (or
+  `-c`) option which accepts a file name and passes the parsed content of a
+  [YAML] or [JSON] file to the [`extension_configs`][ec] keyword of the
+  `markdown.Markdown` class. The contents of the YAML or JSON must map to a
+  Python Dictionary which matches the format required by the
+  `extension_configs` keyword. Note that [PyYAML] is required to parse YAML
+  files.
+
+[cli]: ../cli.md#using-extensions
+[YAML]: http://yaml.org/
+[JSON]: http://json.org/
+[PyYAML]: http://pyyaml.org/
+
+* The [Admonition Extension][ae] is no longer considered "experimental."
+
+[ae]: ../extensions/admonition.md
+
+* There have been various refactors of the testing framework. While those
+  changes will not directly effect end users, the code is being better tested
+  which will benefit everyone.
+
+* Various bug fixes have been made. See the [commit
+  log](https://github.com/Python-Markdown/markdown/commits/master) for a
+  complete history of the changes.

+title: Release Notes for v2.6
+
+# Python-Markdown 2.6 Release Notes
+
+We are pleased to release Python-Markdown 2.6 which adds a few new features
+and fixes various bugs. See the list of changes below for details.
+
+Python-Markdown version 2.6 supports Python versions 2.7, 3.2, 3.3, and 3.4 as
+well as PyPy.
+
+## Backwards-incompatible Changes
+
+### `safe_mode` Deprecated
+
+Both `safe_mode` and the associated `html_replacement_text` keywords are
+deprecated in version 2.6 and will raise a **`DeprecationWarning`**. The
+`safe_mode` and `html_replacement_text` keywords will be ignored in the next
+release. The so-called "safe mode" was never actually "safe" which has resulted
+in many people having a false sense of security when using it. As an
+alternative, the developers of Python-Markdown recommend that any untrusted
+content be passed through an HTML sanitizer (like [Bleach]) after being
+converted to HTML by markdown. In fact, [Bleach Whitelist] provides a curated
+list of tags, attributes, and styles suitable for filtering user-provided HTML
+using bleach.
+
+If your code previously looked like this:
+
+```python
+html = markdown.markdown(text, safe_mode=True)
+```
+
+Then it is recommended that you change your code to read something like this:
+
+```python
+import bleach
+from bleach_whitelist import markdown_tags, markdown_attrs
+html = bleach.clean(markdown.markdown(text), markdown_tags, markdown_attrs)
+```
+
+If you are not interested in sanitizing untrusted text, but simply desire to
+escape raw HTML, then that can be accomplished through an extension which
+removes HTML parsing:
+
+```python
+from markdown.extensions import Extension
+
+class EscapeHtml(Extension):
+    def extendMarkdown(self, md, md_globals):
+    del md.preprocessors['html_block']
+    del md.inlinePatterns['html']
+
+html = markdown.markdown(text, extensions=[EscapeHtml()])
+```
+
+As the HTML would not be parsed with the above Extension, then the serializer
+will escape the raw HTML, which is exactly what happens now when
+`safe_mode="escape"`.
+
+[Bleach]: https://bleach.readthedocs.io/
+[Bleach Whitelist]: https://github.com/yourcelf/bleach-whitelist
+
+### Positional Arguments Deprecated
+
+Positional arguments on the `markdown.Markdown()` class are deprecated as are
+all except the `text` argument on the `markdown.markdown()` wrapper function.
+Using positional arguments will raise a **`DeprecationWarning`** in 2.6 and an
+error in the next release. Only keyword arguments should be used. For example,
+if your code previously looked like this:
+
+```python
+html = markdown.markdown(text, [SomeExtension()])
+```
+
+Then it is recommended that you change it to read something like this:
+
+```python
+html = markdown.markdown(text, extensions=[SomeExtension()])
+```
+
+!!! Note
+    This change is being made as a result of deprecating `"safe_mode"` as the
+    `safe_mode` argument was one of the positional arguments. When that argument
+    is removed, the two arguments following it will no longer be at the correct
+    position. It is recommended that you always use keywords when they are
+    supported for this reason.
+
+### "Shortened" Extension Names Deprecated
+
+In previous versions of Python-Markdown, the built-in extensions received
+special status and did not require the full path to be provided. Additionally,
+third party extensions whose name started with `"mdx_"` received the same
+special treatment. This behavior is deprecated and will raise a
+**`DeprecationWarning`** in version 2.6 and an error in the next release. Ensure
+that you always use the full path to your extensions. For example, if you
+previously did the following:
+
+```python
+markdown.markdown(text, extensions=['extra'])
+```
+
+You should change your code to the following:
+
+```python
+markdown.markdown(text, extensions=['markdown.extensions.extra'])
+```
+
+The same applies to the command line:
+
+```python
+python -m markdown -x markdown.extensions.extra input.txt
+```
+
+Similarly, if you have used a third party extension (for example `mdx_math`),
+previously you might have called it like this:
+
+```python
+markdown.markdown(text, extensions=['math'])
+```
+
+As the `"mdx"` prefix will no longer be appended, you will need to change your
+code as follows (assuming the file `mdx_math.py` is installed at the root of
+your PYTHONPATH):
+
+```python
+markdown.markdown(text, extensions=['mdx_math'])
+```
+
+Extension authors will want to update their documentation to reflect the new
+behavior.
+
+See the [documentation](../reference.md#extensions) for a full explanation
+of the current behavior.
+
+### Extension Configuration as Part of Extension Name Deprecated
+
+The previously documented method of appending the extension configuration
+options as a string to the extension name is deprecated and will raise a
+**`DeprecationWarning`** in version 2.6 and an error in 2.7. The
+[`extension_configs`](../reference.md#extension_configs) keyword should be used
+instead. See the [documentation](../reference.md#extension-configs) for a full
+explanation of the current behavior.
+
+### HeaderId Extension Pending Deprecation
+
+The [HeaderId][hid] Extension is pending deprecation and will raise a
+**`PendingDeprecationWarning`** in version 2.6. The extension will be deprecated
+in the next release and raise an error in the release after that. Use the [Table
+of Contents][TOC] Extension instead, which offers most of the features of the
+HeaderId Extension and more (support for meta data is missing).
+
+Extension authors who have been using the `slugify` and `unique` functions
+defined in the HeaderId Extension should note that those functions are now
+defined in the Table of Contents extension and should adjust their import
+statements accordingly (`from markdown.extensions.toc import slugify, unique`).
+
+[hid]: ../extensions/header_id.md
+
+### The `configs` Keyword is Deprecated
+
+Positional arguments and the `configs` keyword on the
+`markdown.extension.Extension` class (and its subclasses) are deprecated. Each
+individual configuration option should be passed to the class as a keyword/value
+pair. For example. one might have previously initiated an extension subclass
+like this:
+
+```python
+ext = SomeExtension(configs={'somekey': 'somevalue'})
+```
+
+That code should be updated to pass in the options directly:
+
+```python
+ext = SomeExtension(somekey='somevalue')
+```
+
+Extension authors will want to note that this affects the `makeExtension`
+function as well. Previously it was common for the function to be defined as
+follows:
+
+```python
+def makeExtension(configs=None):
+    return SomeExtension(configs=configs)
+```
+
+Extension authors will want to update their code to the following instead:
+
+```python
+def makeExtension(**kwargs):
+    return SomeExtension(**kwargs)
+```
+
+Failing to do so will result in a **`DeprecationWarning`** and will raise an
+error in the next release. See the [Extension API][mext] documentation for more
+information.
+
+In the event that an `markdown.extension.Extension` subclass overrides the
+`__init__` method and implements its own configuration handling, then the above
+may not apply. However, it is recommended that the subclass still calls the
+parent `__init__` method to handle configuration options like so:
+
+```python
+class SomeExtension(markdown.extension.Extension):
+    def __init__(**kwargs):
+        # Do pre-config stuff here
+        # Set config defaults
+        self.config = {
+            'option1' : ['value1', 'description1'],
+            'option2' : ['value2', 'description2']
+        }
+        # Set user defined configs
+        super(MyExtension, self).__init__(**kwargs)
+        # Do post-config stuff here
+```
+
+Note the call to `super` to get the benefits of configuration handling from the
+parent class. See the [documentation][config] for more information.
+
+[config]: ../extensions/api.md#configsettings
+[mext]: ../extensions/api.md#makeextension
+
+## What's New in Python-Markdown 2.6
+
+### Official Support for PyPy
+
+Official support for [PyPy] has been added. While Python-Markdown has most
+likely worked on PyPy for some time, it is now officially supported and tested
+on PyPy.
+
+[PyPy]: http://pypy.org/
+
+### YAML Style Meta-Data
+
+<del>The [Meta-Data] Extension now includes optional support for [YAML] style
+meta-data.</del> By default, the YAML deliminators are recognized, however, the
+actual data is parsed as previously. This follows the syntax of [MultiMarkdown],
+which inspired this extension.
+
+<del>Alternatively, if the `yaml` option is set, then the data is parsed as
+YAML.</del> <ins>As the `yaml` option was buggy, it was removed in 2.6.1. It is
+suggested that a preprocessor (like [docdata]) or a third party extension be
+used if you want true YAML support. See [Issue #390][#390] for a full
+explanation.</ins>

+### Table of Contents Extension Refactored
+
+The [Table of Contents][TOC] Extension has been refactored and some new features
+have been added. See the documentation for a full explanation of each feature
+listed below:
+
+* The extension now assigns the Table of Contents to the `toc` attribute of
+  the Markdown class regardless of whether a "marker" was found in the
+  document. Third party frameworks no longer need to insert a "marker," run
+  the document through Markdown, then extract the Table of Contents from the
+  document.
+
+* The Table of Contents Extension is now a "registered extension." Therefore,
+  when the `reset` method of the Markdown class is called, the `toc` attribute
+  on the Markdown class is cleared (set to an empty string).
+
+* When the `marker` configuration option is set to an empty string, the parser
+  completely skips the process of searching the document for markers. This
+  should save parsing time when the Table of Contents Extension is being used
+  only to assign ids to headers.
+
+* A `separator` configuration option has been added allowing users to override
+  the separator character used by the slugify function.
+
+* A `baselevel` configuration option has been added allowing users to set the
+  base level of headers in their documents (h1-h6). This allows the header
+  levels to be automatically adjusted to fit within the hierarchy of an HTML
+  template.

+
+### Pygments can now be disabled
+
+The [CodeHilite][ch] Extension has gained a new configuration option:
+`use_pygments`. The option is `True` by default, however, it allows one to turn
+off Pygments code highlighting (set to `False`) while preserving the language
+detection features of the extension. Note that Pygments language guessing is not
+used as that would 'use Pygments'. If a language is defined for a code block, it
+will be assigned to the `<code>` tag as a class in the manner suggested by the
+[HTML5 spec][spec] (alternate output will not be entertained) and could
+potentially be used by a JavaScript library in the browser to highlight the code
+block.

+
+### Miscellaneous
+
+Test coverage has been improved including running [flake8]. While those changes
+will not directly effect end users, the code is being better tested which will
+benefit everyone.
