v2.23.0

• The external dependency on jQuery UI was removed.
  A new library jquery.fancytree-all-deps.min.js is now added to the
  distribution. It includes all dependencies on jQuery UI, so the only
  remaining external dependency is jQuery.
  Continue to use jquery.fancytree-all.min.js if jQuery UI is already
  included anyway.

• Refactored the select behavior
  details:

  • [Added] Allow control of selection status propagation with new options:
    unselectable, unselectableIgnore, unselectableStatus.
  • [Added] node option radiogroup enables single-select for child nodes
  • [Added] option opts.noEvents to setSelected(flag, opts)
  • [Improved] Option 'checkbox' can have the string value "radio" (only visual
    effect)

• BREAKING CHANGES:

  • The hideCheckbox option was removed. Use checkbox: false instead.
    Note that the <li class='hideCheckbox'> is still parsed from input
    HTML and converted accordingly.
  • The optional modifier class <div class='fancytree-radio'> was removed.
    This class was used on the container to turn all checkbox items into
    radio buttons.
    Instead, this class is now added to <span class="fancytree-checkbox fancytree-radio">.
    Use the tree.checkox: "radio" option to activate this for the whole tree.
  • The callback signature for the tree.tooltip option has changed to
    tooltip(event, data)

• [Improved] aria option is now on by default

• Use the new dynamic options pattern for
  checkbox, icon, tooltip, unselectable, unselectableIgnore,
  unselectableStatus.
  See also dynamic options.

• [Added] New method node.visitSiblings()

• [Added] #730 ext-persist option expandOpts is passed to setExpanded()
  Allows to suppress animation or event generation.
