1. With great thanks to _Eugene Loza_, we now have a working _Undo_ system for [Castle Game Engine Editor](https://castle-engine.io/manual_editor.php)!

2. You can now edit names of components in the editor’s tree view (click or press F2). Also thanks to _Eugene Loza_!

3. Right-clicking in hierarchy now exposes a context menu with some useful functions, in particular you can add new component as a child of selected. The credit for this goes also to _Eugene Loza_ – thank you!

4. Thanks to _Andrzej Kilijański_, we have a “Clear” button to clear currently displayed warnings.

5. Fixed deleting a component (deletion should be recursive, previously the children were hidden but remained in memory and prevented from reusing the same `Name`).

6. The shell list view is better, with directories.

7. The dialog to open URLs (e.g. for `TCastleScene.URL`) by default starts in project’s [data directory](https://castle-engine.io/manual_data_directory.php), to make it natural to choose files there.
