Version 0.4.0.0

Core

• Plugs and ValuePlugs now accept children (#1043).
• Added child matching to connected Plugs (#1043).
• Added LocalDispatcher.Job and LocalDispatcher.JobPool to track running batches (#1064).
• Failing batches not stop a LocalDispatch job.

UI

• Improved Object section of SceneInspector (#897).
• Added a window for tracking currently running LocalDispatcher jobs (#872).
• Fixed reparenting bug with DispatcherWindows (#1064).

Scene

• Fixed poor performance of Prune/Isolate in presence of SetFilter.
• Added sets support to Parent node (#1065).
• Outputting all cameras, not just the primary camera, to the renderer.
• Added support for per-camera resolution overrides, specified with a "resolutionOverride" V2iData in the camera parameters.

API

• Plugs and ValuePlugs now accept children. CompoundPlug will be deprecated.
• Added BranchCreator::hashBranchGlobals() and computeBranchGlobals(), and implemented them for Parent.
• Added outputCameras() and overload for outputCamera() to RendererAlgo.h.
• Added LocalDispatcher.Job and LocalDispatcher.JobPool to track running batches.

Incompatible changes

• Added additional virtual methods to BranchCreator
• ValuePlug::settable() is no longer virtual

Version 0.3.0.0

Core

• Added SubGraph base class, which Reference and Box now derive from, allowing them both to be enabled/disabled.
• Redesigned Dispatcher registration (#922) (see API section for details).

UI

• Nodes created via the NodeMenu apply default values to their plugs, using the "userDefault" key in the Metadata (#1038).
• Exposed the DispatcherWindow to the public API.

Cortex

• Moved Cortex-specific functionality into new GafferCortex library and module.
  • The Gaffer core itself remains heavily dependent on Cortex, and always will. Here we're splitting out "end user" functionality such as OpHolders and ProceduralHolders, so that GafferCortex can be thought of as the user-visible presence of Cortex within Gaffer.
  • This remains backwards compatible for now via startup files, which allows a grace period for dependent code to update to the new module layout.

RenderMan

• Added basic support for RenderMan volume shaders.

API

• Added Gaffer.NodeAlgo python scope with applyUserDefaults( node ) (#1038).
• Redesigned Dispatcher registration (#922).
  • Dispatchers are registered with Creator functions rather than instances.
  • Added get/setDefaultDispatcherType(), which can be used to create a new instance of the default type.
  • SetupPlugsFn is now a static function that can be registered along with a Creator, rather than a virtual method of Dispatcher instances.
• Added gil release to GafferScene.matchingPaths python binding.
• Fixed StringPlug string substitution bug.
• Catching error_already_set in Dispatcher bindings.

Incompatible changes

• Reference and Box now derive from SubGraph rather than Node or DependencyNode.
• Redesigned Dispatcher registration (#922) (see API section for details).

Version 0.2.1.0

Core

• Expression node optimizations

Scene

• Made ShaderAssignment use the shader type as an attribute name.
• Added Group::nextInPlug() method
• InteractiveRender now updates all attributes, not just shaders

UI

• Dispatcher FrameRange UI displays the value that will actually be dispatched.
• Removed unwanted horizontal padding from frameless Buttons.

Core

• Dispatcher improvements
  • Dispatching can be cancelled via preDispatchSignal() (#929).

  • ExecutableNodes now execute() using the current Context. Multi-context execution can be accomplished using executeSequence( frames ) assuming the client only needs to vary the frame of the current Context. requiresSequenceExecution() can be defined by nodes with special needs (SceneWriter for example), to alert clients that sequence execution is more appropriate.
  • Dispatcher::doDispatch() is now passed a DAG of TaskBatch nodes, simplifying the task of implementing more complex dispatchers.
