Pymdown-extensions

- **NEW**: SuperFences will now allow number ranges in `hl_lines` option. (878)
- **NEW**: Emoji extension now requires custom emoji indexes to take an `options` and `md` argument. The old non-argument format is deprecated and still accepted, but support for indexes with no arguments will be removed at a future time.
- **NEW**: Highlight now allows the specifying of a custom line number class when not using Pygments.
- **FIX**: Better Arithmatex patterns. Fix issue 888 which caused a hang due to a regular expression typo. Also ensure `!tex $$..$$` and `!tex begin{}...end{}` patterns properly don't match if the tail markers are escaped.

Please see [Release Notes](./release.mdupgrading-to-70) for details on upgrading to 7.0.

- **NEW**: MagicLink will now shorten user name and repository links when link shortening is enabled.
- **NEW**: Added MagicLink options `social_url_shortener` and `shortener_user_exclude` were added.
- **NEW**: UML examples are now demonstrated with Mermaid in documentation.
- **NEW**: SuperFences, if using the attribute list format (` {.lang .additional_class, linenums="1"} `) allows
adding additional classes. IDs can be added as well, though Pygments generated code blocks do not have a mechanism to
actually insert IDs. The first provided class will always be treated as the language class.
- **NEW**: Custom SuperFences' formatters should now also include the keyword parameters`classes` and `id_value` to
allow injecting classes and IDs via the now supported attribute list format. If a code block defines no additional IDs
and classes, the old form will be used. Formatters should include `**kwargs` at the end to future proof them from
future changes.
- **NEW**: Deprecate the SuperFences `highight_code` option. As SuperFences syntax has language classes built right in,
disabling the `highlight_code` option makes little sense. While `highlight_code` is still accepted, it currently does
nothing and will be removed at some future time.
- **NEW**: If a custom fence (SuperFences) or inline (InlineHilite) is given the name of `*`, it will override the
default fence logic.
- **NEW**: SuperFences and InlineHilite no longer sync settings from CodeHilite.
- **NEW**: Add new Tabbed extension for general purpose tabbed content in Markdown.
- **NEW**: Deprecate old SuperFences tabbed content feature. This will be removed in 8.0.
- **NEW**: SuperFences' tabbed content classes have changed from `supferfences-tabs` and `superfences-content` to
`tabbed-set` and `tabbed-content` respectively. Old style classes can be enabled with the `legacy_tab_classes` option
in SuperFences. This new option will be retired with SuperFences tabbed content feature in 8.0.
- **NEW**: Upgrade to Twemoji 12.1.5.
- **NEW**: New key codes and key code changes in Keys extension:
- Added `super`, `left-super`, and `right-super` key codes as an alternative to `meta`. Aliases `lsuper` and
`rsuper` were also added.
- Added the `alt-graph` key code with `altgr` alias.
- Added the following new aliases: `lwindows` and `rwindows` for consistency.
- Added new codes `left-meta` and `right-meta` for consistency with other modifiers. Aliases `lmeta` and `rmeta`
were also added.
- Added `left-option`, `right-option`, `left-command`, `right-command`, `left-meta`, and `right-meta` codes for
consistency across similar modifier keys. Additional aliases were added as well: `loption`, `roption`, `lopt`,
`ropt`, `left-opt`, `right-opt`, `lcommand`, `rcommand`, `lcmd`, `rcmd`, `left-cmd`, `right-cmd`, `lmeta`, and
`rmeta`.
- `alt` no longer uses `menu`, `lmenu`, and `rmenu` as key aliases. `context-menu` now uses the alias `menu`.
`context-menu` will display with `Menu` now.
- **FIX**: Numerous deprecation warnings associated with the recent release of Python Markdown 3.2.
- **FIX**: Ensure ExtraRawHTML raises a deprecation warning.
