1. Thanks to _Trung Le (Kagamma)_, you can now use _collection editors_ in [Castle Game Engine Editor](https://castle-engine.io/manual_editor.php) just like in [Lazarus](https://www.lazarus-ide.org/). 

2. Thanks to _Matthias_ ([Free Pascal meets SDL](https://www.freepascal-meets-sdl.net/)), we have an important Tiled bug fixed — in case you used multiple tilesets within one Tiled map. Testcases are within [examples/tiled/map\_viewer](https://github.com/castle-engine/castle-engine/tree/master/examples/tiled/map_viewer) data.

3. On our quest of simplifying CGE API, we recently removed a useless `TInputListener` class (it is now a deprecated alias for [TCastleUserInterface](https://castle-engine.io/apidoc-unstable/html/CastleUIControls.TCastleUserInterface.html)) and the new non-deprecated name for `TUIContainer` is now [TCastleContainer](https://castle-engine.io/apidoc-unstable/html/CastleUIControls.TCastleContainer.html).

4. [view3dscene](https://castle-engine.io/view3dscene.php) supports a new command-line option `--no-x3d-extensions` if you’d like to convert models from various formats (e.g. glTF) to X3D without any [Castle Game Engine X3D extensions](https://castle-engine.io/vrml_x3d.php). While it may make the models a bit less functional in CGE, it makes them more readily useful with other X3D viewers like [X3DOM](https://www.x3dom.org/).

5. During the development of [The Unholy Society](https://unholy-society.com/) for iOS, we noticed a weirdness with `Release` events on iOS, which stem from how iOS reports touchesEnded / touchesCancelled events. There’s nothing we can do about them (and every iOS application suffers from them, as far as we can tell, regardless of the engine/framework used to make it), so they are just documented now at [iOS – Known Problems](https://github.com/castle-engine/castle-engine/wiki/iOS#known-problems).
