Reformatted Release Notes for 2.6.
This format (using subheading rather than lists), allows for easy linking to each individual section of the release notes. I think we should sue this format going forward. Also added an additional example to clarify the deprecation of the special treatment of the 'mdx_' prefix for third party extensions.

- `html_replacement_text` keywords will be ignored in version 2.7. 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.

+ 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 2.7. Ensure that you
+always use the full path to your extensions. For example, if you previously
+did the following:
+
+ markdown.markdown(text, extensions=['extra'])
- html = markdown.markdown(text, [SomeExtension()])
-
- Then it is recommended that you change it to read something like this:

- did the following:
+ $ python -m markdown -x markdown.extensions.extra input.txt
- markdown.markdown(text, extensions=['extra'])
+Similarly, if you have used a third party extension (eg: `mdx_math`), previously
+you might have called it like this:
- You should change your code to the following:
+ markdown.markdown(text, extensions=['math'])
- markdown.markdown(text, extensions=['markdown.extensions.extra'])
+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):
- The same applies to the command line:
+ markdown.markdown(text, extensions=['mdx_math'])
- $ python -m markdown -x markdown.extensions.extra input.txt
+Extension authors will want to update their documentation to reflect the new behavior.
- See the [documentation](reference.html#extensions) for a full explanation
- of the current behavior.

- The [`extension_configs`](reference.html#extension_configs) keyword should
- be used instead. See the [documentation](reference.html#extension-configs)

+### Extension Configs as Part of Extension Name Deprecated
-* The [HeaderId][hid] Extension is pending deprecation and will raise a

- [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`).

-* 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:
-
- ext = SomeExtension(configs={'somekey': 'somevalue'})
-
- That code should be updated to pass in the options directly:
-
- 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:
-
- def makeExtension(configs=None):
- return SomeExtension(configs=configs)
-
- Extension authors will want to update their code to the following instead:
-
- 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:
-
- 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.

-* 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.

-* 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.
