10.0.0-a72
==========
Fixes
-----
- IECore::Enum : Fixed comparison of different Enum types (#1032).
We're now closer to matching Python 3 `enum.Enum` behaviour.
- IECoreMaya::ToMayaMeshConverter : Fixed a bug converting indexed normals (#1033).
10.0.0-a71
==========
Improvements
------------
- IECore :
- Refactored `Enum`, `MenuDefinition`, `MenuItemDefinition` to new style Python classes (#1012).
- MenuDefinition : Added `size`, `item` and `update` methods (#1012, #1013).
- Canceller : Added `cancelled` method (#1019).
- IECoreImage : Added OIIO 2 support (#1011).
- IECoreMaya :
- FnSceneShape : Added ability to promote scene attributes so they can be overriden in Maya (#1029).
- Added `UndoFlush` and updated other Context Managers to be used as decorators (#1029).
- IECoreAlembic : Added support for the `width` primitive variable when reading curves and points (#1017).

Fixes
-----
- IECoreAppleseed :
- Added support for Appleseed 2.1 (#1011).
- Added numerous stability enhancements (#1011).
- IECoreMaya :
- SceneShape VP2 :
- Fixed disappearing geometry in Flat Shaded mode (#1016).
- Fixed partial evaluation of invisible SceneShapes. This is particularly relvant for animation rigs driven by SceneShape output plugs (#1018).
- Fixed internal memory consumption. We now use `IECORE_MAYA_VP2_MEMORY` to track all VP2 related caching (#1018, #1021).
- Fixed several draw errors for expanded shapes, including extra geometry, doubling transformations, and incorrect root bounds (#1024).
- Fixed single component selection for expanded shapes, recently collapsed shapes, and scenes with link locations (ie. instances). Note marquee selection is not yet supported (#1026).
- Fixed crash when switching from VP2 back to VP1 (#1026).
- SceneShape UX :
- Changed radial DAG menu to use `IECoreMaya.Menu` rather than a native Maya menu (#1013).
- Fixed a bug in `FnSceneShape.selectComponentNames()` which broke the radial DAG menu (#1029).
- Fixed a bug that prevented a SceneShape from correctly expanding by tag (#1029).
- Fixed crashes when undoing FnSceneShape operations (#1029).
- LiveScene : Fixed a bug in `hasAttribute()` related to `ieAttr_` attributes (#1029).
- FromMayaEnumPlugConverter : Fixed RunTimeTyped registration (#1030).
- IECoreHoudini :
- Improved error reporting for the SceneCache ROP when exporting mixed curves and free points (#1025).
- Fixed ieMeshInterpolation conversion for mixed poly/subdiv SOPs (#1028).
Breaking Changes
----------------
- IECoreMaya::SceneShapeUI : Changed signature for callbacks registered via `addDagMenuCallback` to take an `IECore.MenuDefinition` rather than a Maya Menu (#1013).
Build
-----
- cmake : General improvements (#1022).
10.0.0-a70
==========
Fixes
-----
- IECoreMaya : Maya 2019 Compatibility (#1007)
- IECoreMaya::FnSceneShape: Fixed shape drawing on expansion (#1010).
Breaking Changes
----------------

==========
Fixes
-----
- IECoreScene::PrimitiveAlgoUtils : Fixed GeoemtricData bug in AverageValueFromVector (#1003).

==========
This is the first official release with Windows support. Big thanks to Eric Mehl and Alex Fuller
for their hard work getting the codebase ready for Windows.
Improvements
------------
- IECoreHoudini
- SceneCache ROP, LiveScene, and DetailSplitter now respect Output SOPs with a fallback to the previous
behaviour (SOP render flag) (#978).
- SceneCache OBJs and SOP now provide a visibilityFilter which can be used to prune invisible shapes.
