 - Default Loading screen supports any image size and ratio ([#8845](https://github.com/BabylonJS/Babylon.js/issues/8845)) ([RaananW](https://github.com/RaananW))
 - Added optional success and error callbacks for freezeActiveMeshes ([RaananW](https://github.com/RaananW))
 - Allow cross-eye mode in photo and video dome ([#8897](https://github.com/BabylonJS/Babylon.js/issues/8897)) ([RaananW](https://github.com/RaananW))
+- Added noMipMap option to the photo dome construction process ([#8972](https://github.com/BabylonJS/Babylon.js/issues/8972)) ([RaananW](https://github.com/RaananW))
