# 0.57.1.0¶

## Features¶

• ClosestPointSampler : Added a new node for sampling primitive variables from the closest point on a source primitive.
• CurveSampler : Added a new node for sampling primitive variables from parametric positions on some source curves.
• ArnoldColorManager : Added a new node for specifying the colour manager for use in Arnold renders (#3523).
• Viewer : Added overlay to Image views to control interactive renders where available (#3419).

## Improvements¶

• InteractiveRender : Improved presentation of render control buttons (#3419).

## Fixes¶

• Spreadsheet : Fixed pattern matching bugs when using \${scene:path} as the selector. In this case, * no longer matches /, and ... is now supported.
• TranslateTool : Fixed problems translating an object with a downstream AimConstraint applied.
• Instancer : Fixed crashes caused by attempts to instance onto a location without a primitive (#3715).
• Script Settings :
• Fixed errors showing the popup menu for the frameRange plug.
• PrimitiveSampler : Added a new base class for nodes which sample primitive variables using an IECoreScene::PrimitiveEvaluator.
• Arnold Renderer : Added support for an ai:color_manager option.
