• NEW: Arithmatex: Wrap MathJax "script" format (non-preview) with a container element just like all other
  Arithmatex output formats.
• NEW: Arithmatex: MathJax (non-generic) form's container element now has the arithmatex class added just like
  everywhere else.
• NEW: Arithmatex: Add options to override HTML element container type of inline and block math.
• NEW: Arithmatex: Add new formatter functions intended to replace old math fenced/inline block formatters. New
  formatter functions are configurable. All others are marked as deprecated and will be removed at some future date.
• NEW: Emoji: Upgraded Twitter emoji database to support latest emoji. It is a known issue that Twitter has
  :man_in_santa_hat: and :mx_claus: backwards -- same for :mrs_claus: and :woman_in_santa_hat:. That is on
  Twitter's side, not ours.
• NEW: Highlight: Add support for the Pygments option linespans.
• NEW: Highlight: Add support for Pygments option lineanchors.
• NEW: Highlight: Add support for Pygments option anchorlinenos.
• NEW: Highlight: Remove legacy_no_wrap_code option.
• NEW: Add support for generating title headers pulled from the Pygments lexer for code blocks. Feature can be
  enabled via the new auto_title option. If a specific name is not preferred, these names can be overridden via
  a user defined mapping called auto_title_map.
• NEW: SuperFences: Allow setting a title, or overriding an auto title via the new title option in a fenced code
  header.
• NEW: SuperFences: Allow adding ID and arbitrary data- attributes on Pygments code blocks. The latter requires
  the attr_list extension to be enabled.
• NEW: SuperFences: Removed old deprecated option highlight_code which no longer did anything.
• NEW: SuperFences: Remove legacy code meant to help with transitioning to new custom fence function format.
• NEW: Tabbed: New alternate style that allows for a scrollable tabs if they overflow. Feature is experimental, see
  docs for more information.
• NEW: Slugs: Add new configurable slugify function that aims to replace all other slugify methods. Deprecate
  uslugify, uslugify_encoded, uslugify_case, uslugify_case_encoded, gfm, and gfm_encoded. slugify takes
  parameters returning a function that performs the desired slug handling. slugify adds new options case="fold" for
  case folding and normalize='<normalize format here>' (uses NFC by default).
• FIX: BetterEm: Fix some complex cases related to "smart" logic. (#1413)
• FIX: EscapeAll: Fix issue where an escaped HTML entity may end up with incorrect slug and incorrect table of
  content entry.

  showing a line number would not render with the proper leading space.
