• Improved live-render edit speed in cases where several LPE based AOV's were being used.

• RenderMan will now abort when attempting to recover non-incremental renders when bucket order is set to anything other than "vertical" or "horizontal".

• In OSL, gettattribute() of the "context" object can be used to access the members of the RixShadingContext scTraits structure "eyePath", "lightPath", "primaryHit", "missContext", "reyesGrid" and "shadingMode".

• Extended widget types for OSL nodes loaded at startup: 'fileInput', 'assetIdInput', 'filename' (non-standard), 'text', 'popup' and 'boolean'.
