+# 2.31.0-0 / Unreleased
+  * 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
+    - [Added] `dnd5.preventSameParent` option
+  * [Added] hook `treeStructureChanged`
+  * [Added] methods `tree.findRelatedNode()`, `node.findRelatedNode()`
+  * [Added] method `node.getPath()`
+  * [Added] methods `$.ui.fancytree.getDragNode()`, `$.ui.fancytree.getDragNodeList()`
+  * [Added] event `updateViewport`
+  * [Added] tree option `.checkboxAutoHide` to hide checkboxes unless selected or hovered.
+  * [Added] tree option `.treeId` to prevent generation of a new sequence if the tree is re-initialized on a page.
+  * [Changed] `.getTree()` now also accepts the tree id string
+  * [Changed] #939: Keep a `partsel` flag that was explicitly set on a lazy node
+  * [Changed] ext-clones: make default key generation more robust against collisions
+  * [DEPRECATED] loaderror and lazyload options now throw an error instead of falling back to the correct loadError and lazyLoad
+  * [DEPRECATED] `tree.applyFilter` was removed
+  * [Fixed] #918 SVG font awesome 5 glyphs remove badge counter when parent node is collapsed
+  * [Fixed] #921 ext-edit respectively focus handling: Internet Explorer scrolls briefly
+    to the top/left of the tree container element after editing a node title if the
+    tree container is partially outside the viewport
+  * [Fixed] #931 Selecting grandparent selects all nodes of radiogroup in selectMode=3
+  * [Fixed] #946 dnd5 - Counter badge shows up, although the drag was cancelled from dragStart callback
+  * [Fixed] #947 dnd5 - dragEnd is fired only when re-ordering nodes within the same parent
+  * [Fixed] missing tree.error() and broken node.error()
+  * [Fixed] a bug in ext-logger
+  * Optimized performance of `expandAll()` and `ext-filter`
+  * Replace jshint/jscs with eslint
+  * Now testing on Puppeteer/Chromium instead of PhantonJS
+  * Use LF on Windows when checking out from git (added .gitattributes)
+  * Update to jQuery 3.4
