Release Notes for 606

Improves "expand all" performance with observed testing improvements of 8x.

When reloading a single plugin or all plugins, the Output window will automatically be cleared to make any fresh output from the new run of the plugin(s) stand out clearly.

For EditableMesh, fixes a bug where removing triangles until a zero-count doesn't remove all triangles from being rendered.

Hide FluidFidelity property when not in aerodynamics beta.

Empty variadic arguments will no longer appear in the Watch window while debugging.

Fixes issue where tab width was not consistent in the Script Editor.

Addresses an Emulation > Device Manager bug where custom devices lose their "Platform" property when that property is changed.

Clicking an Instance link in the Output window, generated by printing an Instance or data structure containing an Instance, will select exactly that Instance and not do anything else.

Fixes an issue where the top-left corner of the Properties window wasn't accepting mouse inputs.

Fixes a regression where setting BasePart.MaterialVariant in the Properties window would not also set the BasePart.Material of the part.

When importing images in the Asset Manager, you may now Shift-select multiple files. Insert will then add them all, whether in the Images pane or the "Recently Imported" pane.

Calling :PivotTo() on a BasePart will no longer fail to move descendant parts in the case where there's no PVInstance directly parented to the part.

Massively improves performance of Shift-selecting instances in the Explorer by limiting the amount of times Selection.SelectionChanged is called.

Avatar Setup will now correctly create parts with SpecialMesh instead of MeshPart for rigid accessories.

Removes loading screen in Play Solo mode, saving 0.6 seconds of transition time.

Improves performance when opening a large number of script tabs at once.

Removes redundant ControlFrame copies under RobloxGui when testing in Studio.

Sound output from the preview widget in Studio now updates when changing the Sound.SoundGroup property.

Part positions are now properly restored when undoing creation or modification of a RigidConstraint. Note that there are still some especially contrived cases where this fix doesn't apply, particularly involving RigidConstraint cycles in the joint graph.
