[pyup-bot]

This PR pins markdown to the latest release 3.8.1.

Changelog

3.8.1

Fixed

* Ensure incomplete markup declaration in raw HTML doesn't crash parser (1534).
* Fixed dropped content in `md_in_html` (1526).
* Fixed HTML handling corner case that prevented some content from not being rendered (1528).

3.8

Changed

* DRY fix in `abbr` extension by introducing method `create_element` (1483).
* Clean up test directory by removing some redundant tests and port
non-redundant cases to the newer test framework.
* Improved performance of the raw HTML post-processor (1510).

Fixed

* Backslash Unescape IDs set via `attr_list` on `toc` (1493).
* Ensure `md_in_html` processes content inside "markdown" blocks as they are
parsed outside of "markdown" blocks to keep things more consistent for
third-party extensions (1503).
* `md_in_html` handle tags within inline code blocks better (1075).
* `md_in_html` fix handling of one-liner block HTML handling (1074).
* Ensure `<center>` is treated like a block-level element (1481).

perceived abbreviations in these strings (1512).
* Ensure `smarty` extension correctly renders nested closing quotes (1514).

Refactor `abbr` Extension

A new `AbbrTreeprocessor` has been introduced, which replaces the now deprecated
`AbbrInlineProcessor`. Abbreviation processing now happens after Attribute Lists,
avoiding a conflict between the two extensions (1460).

The `AbbrPreprocessor` class has been renamed to `AbbrBlockprocessor`, which
better reflects what it is. `AbbrPreprocessor` has been deprecated.

A call to `Markdown.reset()` now clears all previously defined abbreviations.

Abbreviations are now sorted by length before executing `AbbrTreeprocessor`
to ensure that multi-word abbreviations are implemented even if an abbreviation
exists for one of those component words. (1465)

Abbreviations without a definition are now ignored. This avoids applying
abbr tags to text without a title value.

Added an optional `glossary` configuration option to the abbreviations extension.
This provides a simple and efficient way to apply a dictionary of abbreviations
to every page.

Abbreviations can now be disabled by setting their definition to `""` or `''`.
This can be useful when using the `glossary` option.


Fixed

* Fixed links to source code on GitHub from the documentation (1453).

3.6

Changed

Refactor TOC Sanitation

* All postprocessors are now run on heading content.
* Footnote references are now stripped from heading content. Fixes 660.
* A more robust `striptags` is provided to convert headings to plain text.
Unlike, the `markupsafe` implementation, HTML entities are not unescaped.
* The plain text `name`, rich `html`, and unescaped raw `data-toc-label` are
saved to `toc_tokens`, allowing users to access the full rich text content of
the headings directly from `toc_tokens`.
* The value of `data-toc-label` is sanitized separate from heading content
before being written to `name`. This fixes a bug which allowed markup through
in certain circumstances. To access the raw unsanitized data, retrieve the
value from `token['data-toc-label']` directly.
* An `html.unescape` call is made just prior to calling `slugify` so that
`slugify` only operates on Unicode characters. Note that `html.unescape` is
not run on `name`, `html`, or `data-toc-label`.
* The functions `get_name` and `stashedHTML2text` defined in the `toc` extension
are both **deprecated**. Instead, third party extensions should use some
combination of the new functions `run_postprocessors`, `render_inner_html` and
`striptags`.

Fixed

* Include `scripts/*.py` in the generated source tarballs (1430).
* Ensure lines after heading in loose list are properly detabbed (1443).
* Give smarty tree processor higher priority than toc (1440).
* Permit carets (`^`) and square brackets (`]`) but explicitly exclude
backslashes (`\`) from abbreviations (1444).
* In attribute lists (`attr_list`, `fenced_code`), quoted attribute values are
now allowed to contain curly braces (`}`) (1414).

3.5.2

Fixed

* Fix type annotations for `convertFile` - it accepts only bytes-based buffers.
Also remove legacy checks from Python 2 (1400)
* Remove legacy import needed only in Python 2 (1403)
* Fix typo that left the attribute `AdmonitionProcessor.content_indent` unset
(1404)
* Fix edge-case crash in `InlineProcessor` with `AtomicString` (1406).
* Fix edge-case crash in `codehilite` with an empty `code` tag (1405).
* Improve and expand type annotations in the code base (1401).
* Fix handling of bogus comments (1425).

3.5.1

Fixed

* Fix a performance problem with HTML extraction where large HTML input could
trigger quadratic line counting behavior (1392).
* Improve and expand type annotations in the code base (1394).
