Full Changelog: 4.1.0...4.2.0

4.1.0

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 of various objects. These object oriented bounds values are used in a number of actions involving object placement, such as InitialRandomSpawn and PutObject and PlaceObjectAtPoint. 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.

Full Changelog: 4.0.0...4.1.0

4.0.0

What's Changed

• changing InitializeBody to be public from protected to allow AgentMan… by @ekolve in #911
• Bug fixes to RemoveFromScene by @mattdeitke in #915
• Prefab alignment fix by @elimvb in #919
• Asset id update by @winthos in #923
• Fix to objectIds with specific surfaces not showing up in instance_masks when using Instance Segmentation by @winthos in #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: 3.5.1...4.0.0

3.5.1

• Remove CloudRendering from list of default platforms for Linux
• Add proc.wait() for CloudRendering immediately after launch to detect hosts that don't have Vulkan properly configured
• Remove debug red messages from objects

3.5.0

• Add new platform Controller constructor parameter
• Allow users to manually run CloudRendering platform

3.4.0

• Bug fixes and stability improvements to Manipulathor Arm #820

• Adds controlledObjects to object metadata for sim objects that directly control others (eg: objects like StoveKnob now reports which StoveBurner they control in metadata)

• Update to how filled objects update as per issue #844

• Backend update of Agent Controller to streamline components and initialization logic

• Fixes to VideoController to account for changes in backend Agent Controller updates. PR #856

• Updates SetObjectPoses to respect placeStationary parameter correctly

• Fix toward high level held object logic not property resetting agent hand position

• Updates default visibility of red placeable surface surfaces to off in editor.

• Various optimizations and bug fixes to backend logic

3.3.5

• #821 includes bug fixes for InitialRandomSpawn where objects would occasionally break or disappear from the scene.
• #824 and #832 make breaking changes to the temperature decay API.
• #823 provides the ability to set a global random seed.
• #829 allows --height and --width to be passed into ai2thor-xorg start.
• #835 updates cameraOrthSize in the metadata when the (deprecated) action ToggleMapView is called.
• #816 provides internal updates to AddThirdPartyCamera

3.3.4

• #814 adds official support for a top-down camera (deprecating the private ToggleMapView). To use it, run:

from ai2thor.controller import Controller
event = controller.step(action="GetMapViewCameraProperties")
controller.step(
    action="AddThirdPartyCamera",
    **event.metadata["actionReturn"]
)

• #801, #803, and #805 improve the usability of ManipulaTHOR.
• #808 fixes a logging bug on the Python side.
