# 2.31.0 / 2019-05-30
  * New extension **ext-grid** (experimental)<br>
    This is a variant of `ext-table` that introduces viewport support, which
    allows to maintain *huge* data models while only rendering as many DOM elements as necessary.<br>
    Main changes:
    - A viewport is defined by the number of visible rows (`tree.viewport.count`) and the index of the first visible row (`.start`)
    - When scrolling, rows are not hidden, but removed and replaced. (This implies that the contents of embedded input fields should be written into the model immediately.)
  * Refactored **ext-dnd5**<br>
    Some **breaking changes** were made, mainly to improve handling of the dropEffect
    (note that ext-dnd5 was and still is experimental and in progress).
    - Remove  `dnd5.dropEffect` callback option (set `data.dropEffect` instead)
    - Remove  `dnd5.dragImage` callback option (call  `data.dataTransfer.setDragImage()`
    - and set `data.useDefaultImage = false` instead)
    - Rename `dnd5.preventRecursiveMoves` to `dnd5.preventRecursion`
    - `dnd5.preventVoidMoves` now only aplies to 'move' operations, so we can *copy* before self

# 2.27.0 / 2017-12-16
  * **BREAKING CHANGES:**
    - `node.type` is now a first-class property of FancytreeNode.
      Node data `{..., type: "foo"}` is now available as `node.type` (before: `node.data.type`).
    - The properties `tree.types` and `tree.columns` have been added to Fancytree.
      If passed with source data, they are now available directly instead of
      `tree.data.types` or `tree.data.columns`.
  * **Support patterns for node types:**
    - The properties `node.type` and `tree.types` are recommended to implement node-type
      specific configuration ([details](https://github.com/mar10/fancytree/wiki/TutorialNodeTypes)).
    - Event `data` argument contains `typeInfo == tree.types[node.type]`.
  * **Improved ext-glyph:**
    - [Added] support for ligature icons (e.g. [material icons](https://material.io/icons/)).
    - [Added] `icon` option can now return a dict to create a ligature icon.
  * **Improved tree.loadKeyPath():**
    - [Added] support for a custom path segment matcher.
      This allows to have key paths with segments other than `node.key`.
    - [Improved] the returned deferred promise now triggers `progress()` events which can
      be used instead of the callback.
  * The property `tree.columns` was added to Fancytree. Currently only reserved as
    recommended pattern to pass global meta-data for ext-table.
  * [Added] ext-edit: new trigger mode `clickActive` for option `triggerStart: [...]`.
  * [Added] #798 Tooltip support for icons (dynamic option `iconTooltip`).
  * [Added] #808 Pass custom storage providers to ext-persist.
  * [Improved] ext-table no longer needs empty tbody/tr if thead is present.
  * [Fixed] #796 UMD requirements for node/CommonJS
  * [Fixed] #803 jquery.fancytree.ui-deps.js does not override existing widgets.
  * [Fixed] #815 `<mark>` element missing in filtered nodes (minified bundle, IE 11).

  * [Added] Material Design demo
  * [Added] Demo for Fancytree inside a jquery-confirm popup
  * [Changed] String representation is now `"FancytreeNode@_4[title='My name']"`
  * [DEPRECATED] `tree.clearCookies()`. Use <del>`tree.clearData()`</del> `tree.clearPersistData()` instead.

# 2.25.0 / 2017-10-31
  * **BREAKING CHANGES:**
    - The `dist/src/` folder was renamed to `dist/modules`.
    - Some directories like `demo/` are no longer part of the npm install.
  * **Improved Module Support and Distribution**<br>
    - The `dist/` folder now includes a `modules/` directory with fancytree core
      and all extensions.
    - All modules have UMD wrappers with defined dependencies.
    - Internal jQuery UI dependencies are deployed as module and implicitly loaded.
    - `jquery.fancytree/dist/modules/jquery.fancytree` is defined as
      package main module, so Fancytree can be included using a simple<br>
      `fancytree = require('jquery.fancytree')`.<br>
      See [the docs](https://github.com/mar10/fancytree/wiki/TutorialIntegration)
      for details.
    - All modules now return the
      [$.ui.fancytree object](https://wwWendt.de/tech/fancytree/doc/jsdoc/Fancytree_Static.html).

  * [Fixed] #761: ext-dnd5 throws exception when tree is empty
  * [Fixed] #764: ext-filter breaks links
  * Updated jsdoc to 3.5

# 2.23.0 / 2017-05-27
  * **The external dependency on jQuery UI was removed**.<br>
    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.<br>
    Continue to use `jquery.fancytree-all.min.js` if jQuery UI is already
    included anyway.

  * **Refactored the select behavior**<br>
    [details](https://github.com/mar10/fancytree/wiki/SpecSelect):
    <!-- [details](https://github.com/mar10/fancytree/wiki#selection-and-checkboxes) -->

      `unselectable`, `unselectableIgnore`, `unselectableStatus`.

    * [Added] option `opts.noEvents` to `setSelected(flag, opts)`
    * [Improved] Option 'checkbox' can have the string value "radio" (only has
      the visual effect of replacing the icon)

  * **BREAKING CHANGES:**
    * The `hideCheckbox` option was removed. Use `checkbox: false` instead.<br>
      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.<br>
      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`.<br>
    See also <a href="https://github.com/mar10/fancytree/wiki#dynamic-options">dynamic options</a>.
  * [Added] New method `node.visitSiblings()`
  * [Added] #730 ext-persist option `expandOpts` is passed to setExpanded()
    Allows to suppress animation or event generation.

    (see also the [theming tutorial](https://github.com/mar10/fancytree/wiki/TutorialTheming))
    * [Added] `options.icon` option/callback.<br>
      Valid values are true, false, a string containing a class name or image
      url, or a callback returning that.
    * [Changed] `node.icon` option. Valid values are true, false, or a string
      containing a class name or image url.<br>
      This option existed before, but was stored in the `node.data.icon` namespace,
      and did not accept class names.
    * [DEPRECATED] `options.iconClass` callback: use `options.icon` instead
    * [DEPRECATED] `options.icons`: use `options.icon` instead
    * [DEPRECATED] `node.data.iconclass` option: use `node.icon` instead

# 2.13.0 / 2015-11-16
  * [Changed] If a node is initalized as `lazy: true`, and `children: []`,
    treat it as 'loaded leaf node'.<br>
    This is consistent with a lazy node that has no children property at all (i.e.
    `undefined`). This would issue a lazyLoad event and a resopnse of `[]` would
    mark the node as leaf node.
