7.0.0rc1

7.0rc1

• 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 parametersclasses 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.
