Version 0.10.0.0

Core

• Reimplemented paths framework in C++ (#1190). This gives much
  improved performance - 10x or more speed improvements in the
  SceneHierarchy panel.
• Fixed subprocess hangs seen when dispatching renders inside Maya.
• Restored compatibility with references from prior to version 0.8.0.0.

UI

• Added bookmarks system for NodeGraph (#849).
  • Bookmark nodes using the right-click node context menu
  • Connect plugs to bookmarked nodes using the right-click plug
    context menu.
• Added NodeGraph Ctrl+Click to select all downstream nodes (#941).
• Added additional "Edit/Select Connected" menu items
• Fixed "Edit/SelectConnected" menu items to ignore invisible nodes.
• Fixed "Edit/SelectAll" menu item to ignore invisible nodes (#1207).
• Highlighted plugs at non-default values in the NodeEditor (#1216).
• SceneInspector
  • Significant performance improvements.
  • Added name based filtering for options and attributes (#1159).
  • Added query caching.
• Fixed bug whereby Widget.setVisible( notABool ) could cause problems.
• Fixed clearing of StandardNodeGadget errors for non-DependencyNodes.

Scene

• Added "mode" plug to Set node. This allows paths to be added to or
  removed from existing sets, in addition to the old behaviour of
  creating a new set (or replacing an existing one of the same name).
• Added ClippingPlane node.
• Added "enabled" plug to Filter nodes (#1196).
• Added FilterSwitch node (#1197).
• Added "name" plug to Duplicate node, to provide control over the
  names given to the duplicates (#1200).

Appleseed

• Added photon target attribute.
• Added sampler option.
• Synced default options with new Appleseed defaults.

Cortex

• Added UI hint to control the visibility of the header in the
  ParameterisedHolder node UI.

API

• GraphGadget
  • Added degreesOfSeparation argument to upstreamNodeGadgets() method.
  • Added downstreamNodeGadgets() and connectedNodeGadgets() methods.
• EditMenu
  • Added scope() method. This should be used by custom edit menu
    commands to ensure they operate on the right portion of the
    node graph.
• CompoundVectorParameterValueWidget
  • Added support for "showIndices" parameter user data.
• PathMatcher
  • Added addPaths() and removePaths() methods, each taking a second
    PathMatcher to provide the paths.
• Serialisation
  • Made classPath() and modulePath() methods compatible with passing
    a class as well as an instance.
• PathListingWidget
  • Added setSortable() and getSortable() methods.
• Added MatchPatternPathFilter
• Added bindings for SceneAlgo camera() and shutter() functions.
• Metadata
  • Added control over persistence of instance values.
• Added preprocessor macros for gaffer version numbers.

Incompatibilities

• Path
  • The info API has been replaced with a property API. Emulation
    for the old API exists, but it has been deprecated.
  • Properties must derive from RunTimeTyped, whereas info could
    contain any python type.
  • Subclasses now must implement the copy() method.
• PathListingWidget
  • Column python class has been replaced with several specialised
    C++ subclasses. It is no longer possible to derive from Column
    in python.
• GraphGadget
  • Added argument to upstreamNodeGadgets() method.
• GafferScene::Filter
  • Renamed "match" plug to "out". Backwards compatibility is
    provided by a getattr alias in Python.

Build

• Updated public build to use Cortex 9.0.0-b4.
• libGafferUI now links with Qt. This must be considered when building
  Gaffer to be hosted inside other applications.
• Requires subprocess32 python module.
• Added subprocess32 to dependencies build process.
