Version 0.9.0.0

This is primarily a bugfix release.

Core

• Documented all nodes and plugs.
• Improved Reference workflow
  • Boxes exported for referencing contain new default values for all
    promoted plugs to match their current values on the Box.
  • When reloading a reference, only values the user has changed from
    their defaults will be kept. Other values will be updated from the
    new reference.
  • Box metadata is included when exporting for referencing. This
    means that colours and descriptions set via the UIEditor will
    be transferred onto any Reference nodes which load the exported
    reference (#1171).
• Added "-threads" command line argument to Gaffer.Application
• Fixed "gaffer execute" error handling

Cortex

• Documented all nodes and plugs.

Scene

• Added hack for controlling TBB concurrency from SceneProcedural
  • Using the GAFFERSCENE_SCENEPROCEDURAL_THREADS environment variable

RenderMan

• Fixed hangs caused by deleting or reconnecting a paused
  InteractiveRenderManRender node.

Appleseed

• Fixed render threads and texture memory options.

Image

• Fixed bug which prevented serialisation of read only FormatPlugs.

UI

• Fixed creation of expressions for BoolPlugs.
• Fixed context used by scene view camera chooser.

API

• Added Metadata::registerNode() method. This allows all the metadata
  for a node and its plugs to be registered with a single function call
  (#1160).
• Added GafferTest.TestCase.assertNodesAreDocumented().
• Serialisation
  • Added serialisation argument to Serialiser::constructor().
  • Added Serialisation::parent() accessor.
• ValuePlug
  • Simplified handling of default values.
  • Added isSetToDefault() method.
• Made CompoundDataPlug::addMember() set default value for name plug
  (#935).
• Added Python bindings for tbb::task_scheduler_init

Incompatibilities

• Added argument to virtual method Serialiser::constructor().
• Changed layout of ValuePlug classes.
• Removed virtual overrides from some ValuePlug classes.
• Added virtual method to ValuePlug.

Build

• Updated public build to use Cortex 9.0.0-b3.
• Included Shiboken module in release packages.
