**Full Changelog**: https://github.com/allenai/ai2thor/compare/4.1.0...4.2.0

What's Changed
* Internal updates to color changer resources and cloud rendering quality
* Further efficiency updates to specific surfaces not showing up in instance_masks when using Instance Segmentation. This issue was fixed in version 4.0.0, but the method of rendering the surfaces has been updated.
* Various Sim Object collider fixes, including trigger boxes on the desk in FloorPlan309 addressing issue 965
* Fix to object oriented bounding box rotation assignment which resulted in offset object bounds for some sim objects in various scenes. See below in "Breaking Changes" for further details.

Breaking Changes
This release contains a change that potentially modifies SimObjects in all scenes. The change involves correcting the values of the coordinates for the [`objectOrientedBoundingBox`](https://ai2thor.allenai.org/ithor/documentation/environment-state/#object-metadata-objectorientedboundingbox) of various objects. These object oriented bounds values are used in a number of actions involving object placement, such as [`InitialRandomSpawn`](https://ai2thor.allenai.org/ithor/documentation/objects/domain-randomization/#initial-random-spawn) and [`PutObject`](https://ai2thor.allenai.org/ithor/documentation/interactive-physics/#sub-put-object) and [`PlaceObjectAtPoint`](https://ai2thor.allenai.org/ithor/documentation/interactive-physics/#sub-place-object-at-point). All of these affected actions will now execute with more accuracy, but in turn will have different results in terms of final placement of objects when compared to previous versions of AI2-THOR prior to this fix.

What's Changed
* changing InitializeBody to be public from protected to allow AgentMan… by ekolve in https://github.com/allenai/ai2thor/pull/911
* Bug fixes to `RemoveFromScene` by mattdeitke in https://github.com/allenai/ai2thor/pull/915
* Prefab alignment fix by elimvb in https://github.com/allenai/ai2thor/pull/919
* Asset id update by winthos in https://github.com/allenai/ai2thor/pull/923
* Fix to objectIds with specific surfaces not showing up in instance_masks when using Instance Segmentation by winthos in https://github.com/allenai/ai2thor/pull/939

Breaking Changes
This release contains a change that modifies every SimObject in all scenes. The change involved modifying the position and rotation of every object which results in different objectIds. If you rely on the existing positions of objects or cache objectIds, please validate your code works with this new release before launching any training.


**Full Changelog**: https://github.com/allenai/ai2thor/compare/3.5.1...4.0.0

* Add proc.wait() for CloudRendering immediately after launch to detect hosts that don't have Vulkan properly configured
