  function that adds a class to small action posts (pins, closing topics, etc)

  for server-side errors when submitting on the composer.

  HighlightJS plugins. See https://highlightjs.readthedocs.io/en/latest/plugin-api.html
  for documentation.

[1.3.0] - 2022-05-29

[1.2.0] - 2022-03-18

Added

• Adds registerCustomLastUnreadUrlCallback, which allows users to register a custom
  function that returns a last unread url for a topic list item. When multiple callbacks
  are registered, the first non-null value that is returned will be used.

[1.1.0] - 2021-12-15

Added

• Adds addPosterIcons, which allows users to add multiple icons to a poster. The
  addition of this function also makes the existing addPosterIcon now an alias to this
  function. Users may now just use addPosterIcons for both one or many icons. This
  function allows users to now return many icons depending on an attrs.

[1.0.0] - 2021-11-25

Removed

• Removes the addComposerUploadProcessor function, which is no longer used in
  favour of addComposerUploadPreProcessor. The former was used to add preprocessors
  for client side uploads via jQuery file uploader (described at
  https://github.com/blueimp/jQuery-File-Upload/wiki/Options#file-processing-options).
  The new addComposerUploadPreProcessor adds preprocessors for client side
  uploads in the form of an Uppy plugin. See https://uppy.io/docs/writing-plugins/
  for the Uppy documentation, but other examples of preprocessors in core can be found
  in the UppyMediaOptimization and UppyChecksum classes. This has been done because
  of the overarching move towards Uppy in the Discourse codebase rather than
  jQuery fileupload, which will eventually be removed altogether as a broader effort
  to remove jQuery from the codebase.

Changed

• Changes addComposerUploadHandler's behaviour. Instead of being only usable
  for single files at a time, now multiple files are sent to the upload handler
  at once. These multiple files are sent based on the groups in which they are
  added (e.g. multiple files selected from the system upload dialog, or multiple
  files dropped in to the composer). Files will be sent in buckets to the handlers
  they match.
