Replaced waitForLongProcess with submitTask for undo/redo in RobloxStudioVerbs and ChangeHistoryService.

Added strict typing to playerscripts.

Removed AvatarJointPositionType.

table.insert(T, idx, v) will change is behavior when idx < 1: instead of shifting the entire table by 1, it will simply insert the value at index idx, similarly to what happens when idx > #T. This is necessary to prevent table.insert from going into an almost-infinite loop when idx is a negative value; note that all uses of table.insert where idx is not in [1, #T+1] range are very likely bugs, and script analysis will start warning about some of them.

Luau will allow x["foo"] when x is an instance of a class.

Added new pathfinding path waypoints debug visualization.

Added deferred Lua resumption point to runservice start.

Added a parameter that controls intermediate waypoint spacing where math.huge means no intermediate waypoints.

Added an alias for MeshPart.TextureID with consistent casing to other properties.

Added a debug visualizer for adaptive timestepping.

Added a new Velocity Stretch property for particle emitters that have the VelocityParallel orientation that elongates the particle shape in the direction of their velocity based on the velocity magnitude.

Added new methods for scheduling threads for resumption on Heartbeat to the task library.

Added AssetType.TShirt (alias for AssetType.TeeShirt, which is still available)

Removed the HumanoidDefaultAssets folder from beneath StarterPlayer.

Added an option on Workspace (HumanoidOnlySetCollisionsOnStateChange) that will change how the collision on humanoid body parts are set. If enabled, body parts collision states will only be updated when changing humanoid states (ex. run to jump), adding a character to the workspace, modifying an existing child of the character or adding or removing new instances under the character. At first, by default, this feature will be set to be disabled and the body parts will behave as they do today. In the future, though, the default option may change to enabled and will execute the behavior described above.

Fixed an issue where Toolbox could show the wrong categories in the dropdown on initial load.

Fixed a crash when clicking CreatePath in the Object Browser.

Fixed an issue with the Animation Clip Editor not deactivating when selecting an object in the Explorer.

Resumption of threads yielded by task.synchronize() are no longer throttled.

Minor improvement for raycast broadphase perf.

Luau linter now displays warnings for erroneous or inefficient uses of table.insert/table.remove.

MVP Clouds phase 1 release. Clouds object must be moved or placed under Workspace/Terrain to become visible.

Luau-powered autocomplete now knows the type of resources in the data model.

Phase 1b cloud sampling improvements.

More detailed Ambient Occlusion in highest graphics quality setting on desktop.

Align Position and Align Orientation constraints have a new OneAttachment mode. When the constraints are in this mode the body that owns attachment0 will be the only body to move. For Align Position the attachment0 will be moved to the specified position. For Align Orientation the body will be rotated to the specified orientation, specified by both a primary and secondary axis. If primary axis only is true, then only the primary axis is used.

Animation data will not be saved for non-joints.
