  +
  +- Restore support for `{@link}` tags in markdown documents.

  +- Add support for additional comment styles, #1433.
  +- Add support for `@group` tags, #1652.

  +- Theme: Show toggles for all modifier tags used in a project to allow users to filter by deprecated/alpha/beta, etc.

  ### Breaking Changes
  -- TODO: The behavior of `@inheritDoc` has changed... describe how
  -- The `gaSite` option has been removed since Google Analytics now infers the site automatically.

  - Links are no longer be resolved against a global list of all symbols. See [the documentation](https://typedoc.org/guides/link-resolution/) for details on link resolution.

  -- TypeDoc will now warn if part of a comment will be overwritten due to use of `@inheritDoc` instead of silently dropping part of the comment
