Version 9.10.0

IECoreArnold

• Remove support for Arnold < 4.1.
• Support for progressive renders.
• ParameterAlgo
  • Support for arrays in getParameter().
  • Support for RGBA and Point2 parameters.
  • Support for V3fVectorData.
• Flipped t coordinate for mesh uvs.
• Suppressed conversion of stIndices primvar.

Version 9.9.1

Build

• Added INSTALL_ARNOLDPYTHON_DIR build option, to specify an independent location
  for the installation of the IECoreArnold python module.
• Fixed linking of IECoreArnold.

Version 9.9.0

IECore

• Python Module
  • Use RTLD_GLOBAL to load C++ modules.

IECoreMaya

• Added a MightHaveFn to IECoreMaya::LiveScene::registerCustomAttributes().
  • If MightHaveFn is specified, it will be called before NamesFn to allow a cheap early out.

IECoreHoudini

• Implemented Cob GEOIO_Translator::fileStat to return the bounding box from the cob header.

IECoreArnold

• Renderer
  • Apply name to camera nodes.
  • Support "ai:shape:" attribute prefix.
  • Add support for creating Arnold volume nodes.
• Add SphereAlgo with conversion from IECore::SpherePrimitive.

Build

• Fixed PYTHONPATH for IECoreArnold tests
• Updated SConstruct and tests for Arnold 4.2

Version 9.8.0

IECoreMaya

• Added plug conversion for MPointArray to IECore::Vector3f/3d (3d default) with Point interpretation.
• Updated plug conversion for VectorArray to use Vector interpretation (rather than Numeric).
• Preventing primary UV Set from being exported twice.
• ieSceneShape expansion functions can optionally preserve the original namespace of the parent.

IECoreRI

• Added initial support for 3delight OSL via NSI

IECoreAppleseed

• Renamed volume priority attribute to medium priority.

Version 9.7.1

IECore

• LinkedScene : The message for linked ancestor tags is now Debug level instead of Warning.

IECoreHoudini

• Fixed "name" attribute bug in IECoreHoudini::LiveScene, which was triggered by using an attribwrangle on the name attribute.

Version 9.7.0

IECore

• Fixed potential crash in MeshPrimitiveEvaluator::barycentricPosition() (#475).
• Fixed ConfigLoader to ignore duplicate paths. Note that this may change configuration
  behaviour for malformed paths with duplicates (#474).

IECoreArnold

• Added support for both deformation and transform blur (#473).
• Refactored all Cortex->Arnold conversion functionality into new Algo.h headers,
  removing the old FromCoreConverter based classes. This does represent a compatibilit
  break, but IECoreArnold is in contrib, where no compatibility guarantees exist.
• Fixed warnings relating to the data type of Arnold's visibility parameter, which
  has been changed to AtByte from AtInt.

Version 9.6.1

IECore

• MessageHandler handles python exceptions before they get to c++

IECoreMaya

• Sorting childNames during ieSceneShape expansion

IECoreAppleseed

• Added nested volume priority attribute

Version 9.6.0

IECore

• Added support for procedurals without bounds
• Fixed time remapping for old style link attributes in LinkedScenes

IECoreHoudini

• Fixed crash when converting integer and float list attributes in Houdini

IECoreAppleseed

• Fixed attribute stack bug

IECoreRI

• Added support for procedurals without bounds

IECoreGL

• Added support for procedurals without bounds

IECoreArnold

• Added support for procedurals without bounds

IECoreMaya

• Optimized IECoreMaya SceneShape expansion

Version 9.5.0

IECoreNuke

• Adding support for PointsPrimitives in Nuke scene reader

Version 9.4.0

IECore

• Added unit tests for IECore.M33f/M44f indexing

IECoreHoudini

• Houdini can now round trip M33f and M44f primvars, including detail attributes/constant primvars.
