  * Added support for template styles
  * Expose content inside <includeonly> to editors via data-mw attribute
  * Support directionality for references
  * A bunch of cleanup and bug fixes in paragraph wrapping for improved compliance
    with PHP parser output. Move to DOM based p-wrapping of unwrapped bare text

  Notable html -> wt changes:
  * Scrub DOM to convert <p></p> sequences to NL-emitting normal forms
    This now translates empty lines entered in VE to empty lines in wikitext
  * Add new lines before and after lists in wikitext
  * Improve templatedata spec compliance wrt leading and trailing newlines

  * Distinguish between inserted & deleted diff markers

  Infrastructure:
  * Make the Sanitizer "static" and decouple it from the parsing pipeline
  * Removed < node v6 compatibility
  * Migrate to jsdoc instead of jsduck for documentation
  * Allow users to dynamically configure new wikis
  * Addressed nsp-triggered security advisories
  * Updated domino and other dependencies

  Extensions
  * Cleanup of the extension API to reduce exposure of Parsoid internals
  * Migrated native Parsoid extensions to the updated extension API
  * Native Parsoid implementation of <poem>

  Performance fixes:
  * Mostly minor tweaks:
    - Performance improvements in the TokenTransformManager
    - Add a fast path to avoid unnecessarily retokenizing the extlink href
    - Test for a valid protocol before attempting to tokenize extlink content
    - Ensure ref.cachedHtml isn't being regenerated needlessly
    - Suppress autoInsertedEnd flags where not required

  Cleanup:
  * Split up large utility classes into smaller functional groups

  Infrastructure:
  * This release requires clients (VE, etc.) to return a 1.6.0 and

    return a HTTP 406. This can be fixed by updating VE (or relevant
    clients) to a more recent version.

    dev and non-dev dependencies

  Cleanup:

    new jsdoc-wmf-theme for documentation

  * Lint multiple colon escaped links (incorrect usage)
  * Add an API endpoint to get lint errors for wikitext
  * Turn off ignored-table-attr output
  * Add detection for several wikitext patterns that render differently
    in Tidy compared to a HTML5 based parser (Parsoid, RemexHTML).
