# 0.14.0.0
==========
UI
-----------------------------------------------------------------------
- NodeGraph
- Improved "Select Affected Objects" menu item. This is now available
on filters as well as on scene processors.
- Added support for dragging objects from the Viewer and SceneHierarchy
and dropping them onto scene processors and PathFilters, to specify
the affected objects.
- Dragging onto a node replaces the current paths.
- Shift+Drag adds to the current paths.
- Control+Drag removes from the current paths.
- Added plug context menu for moving promoted plugs on Boxes.
- NodeEditor
- Added "Select Affected Objects" menu item in the tool menu for
filters and scene processors.
- UIEditor
- Added + button for adding plugs, and - button for deleting them.
- Added the ability to create nested sections and drag+drop plugs
between them.
- Viewer
- Fixed grid and gnomon menus.
Core
-----------------------------------------------------------------------
- Expression
- Added support for setting multiple plugs from one
expression (#1315).
- Added support for vector, color and box outputs (#1315).
- Added support for assigning to plugs within conditional
branches (#1349).
Scene
-----------------------------------------------------------------------
- Improved ParentConstraint so it is acts more like the equivalent
parenting operation, and maintains the local transforms of the
objects being constrained. Note that this is a change of behaviour,
but one that we feel is much for the better.
- Fixed ShaderAssignment to allow referencing of promoted shader input
plugs.
API
-----------------------------------------------------------------------
- Added `parallelTraverse()` and `filteredParallelTraverse()` methods
to SceneAlgo. These make it trivial to traverse all locations in a
scene using multiple threads.
- Added inputTransform argument to `Constraint::computeConstraint()`.
- Removed TransformPlugValueWidget.
- Used Plug rather than CompoundPlug in several places. CompoundPlug
is being phased out because the Plug base class is now perfectly
capable of having child plugs.
- `ExecutableNode::dispatcherPlug()`
- LocalDispatcher dispatcher plug
- `Shader::parametersPlug()`
- Fixed support for boost python object methods as menu commands.
- Pointer
- Fixed `registerPointer()` method.
- Added binding for `registerPointer()`.
- Added `scoped` argument to `Signal.connect()` python bindings.
- Added `SignalClass` for binding signals, and deprecated the old
`SignalBinder`.
- Added support for binding signals with 4 arguments.
- Added `LazyMethod.flush()` method.
- Fixed update bug in `PathListingWidget.setSelectedPaths()`.
- Added support for "nodule:type" metadata to control the type
of nodule created for a plug. This should be used in preference
to `Nodule::registerNodule()`, which has been deprecated.
- Added support for modifying CompoundNodule orientation, spacing
and direction using plug metadata.
- Improved signalling of instance metadata changes.
- Added default arguments for ValuePlug constructor arguments.
Incompatibilities
-----------------------------------------------------------------------
- Changed Constraint::computeConstraint() function signature.
- Changed ParentConstraint behaviour to include the local transform of the constrained object.
- Removed TransformPlugValueWidget.
- Changed plug type returned by ExecutableNode::dispatcherPlug().
- Changed Dispatcher::SetupPlugsFn signature.
- Changed ExecutableNode::dispatcherPlug() signature.
- Changed Shader::parametersPlug() to Plug rather than CompoundPlug.
- Removed asUserPlug arguments from Box promotion methods. Plugs are
now always promoted directly under a box, and never as user plugs.
- Changed signature of `Nodule::registerNodule()` when registering a subclass.
- Changed signature of CompoundNodule constructor, which now accepts a Plug
rather than CompoundPlug.
- Replaced UIEditor setSelectedPlug()/getSelectedPlug() methods with
setSelection()/getSelection().
- Added arguments to Metadata signals.
# 0.13.1.0
==========
Apps
-----------------------------------------------------------------------
- Test app can now run multiple named test cases, specified via the
"testCases" command line argument.
- Fixed errors caused by special characters in .gfr filenames.
UI
-----------------------------------------------------------------------
- Fixed unwanted viewport scrolling when dragging from one NodeGraph
into another, or from the NodeEditor across a NodeGraph (#1321).
- Hid Viewer diagnostic modes for unavailable renderers.
- Fixed SceneInspector inheritance and history windows, which were broken
in 0.13.0.0.
- Fixed ObjectWriter UI, which was broken in 0.13.0.0.
OSL
-----------------------------------------------------------------------
- Added utility shaders for float maths and noise.
Image
-----------------------------------------------------------------------
- Fixed bug in DeleteChannels::hashChannelNames().
Houdini
-----------------------------------------------------------------------
- Added support for Houdini 14 (requires Cortex 9.0.0-b7).
API
-----------------------------------------------------------------------
- Added GafferUI._qtObject method.
- PlugLayout
- Added layoutSections() method.
- Added section argument to layoutOrder() method.
Build
-----------------------------------------------------------------------
- Added support for Boost >= 1.54.
- Fixed Appleseed packaging. We were omitting the directory containing
the Cortex display driver.
# 0.13.0.0
==========
Apps
-----------------------------------------------------------------------
- Improved error message for execute app.
Core
-----------------------------------------------------------------------
- Improved Dispatcher
- Stopped merging of identical tasks from different nodes.
We decided that this auto-merging caused more confusion than it
was worth, and it may actually have prevented useful executable
graphs which would have been intentionally running identical
tasks at different points in the graph.
- Added cycle detection.
UI
-----------------------------------------------------------------------
- Avoided unnecessary rebuilds of MenuBar menus. This can improve
performance for slow-to-build custom menus.
- Added font file browser to the Text node.
- Improved NodeGraph plug tooltips - they now contain the plug description.
- Plugs may now be promoted to Box level via the right click plug
menu in the NodeGraph.
- Fixed search box in file open dialogues.
- Improved dialogues for picking scene paths
- Opened in tree mode rather than list mode
- Removed unnecessary columns
- Added filtering to display only cameras where appropriate
- CustomAttributes/DeleteAttributes
- Added right click menu for quickly adding attributes from the
currently selected object.
- Viewer
- Added shading mode menu. This allows the default shading to be overridden
with another shader. Currently configured menu entries allow visualisation
of shader assignments and visibility for RenderMan, Arnold and Appleseed
(#1037).
- Improved error handling.
- SceneInspector
- Improved shader display in attributes section. The node colour of the
assigned shader is used as the background colour.
- Improved performance (#1050).
- Node UIs
- Added tool menu to NodeEditor
- Added support for metadata-driven activators.
- Added support for metadata-driven section summaries.
- Added support for metadata-driven custom widgets.
Scene
-----------------------------------------------------------------------
- InteractiveRender
- Fixed crash when deleting a running InteractiveRender.
- Fixed coordinate system update problem.
- Fixed bug preventing filter plugs from being promoted to Boxes.
- Improved set computation
- Separated the computation of sets from the computation of globals.
This should prevent delays caused when calculating large unneeded
sets along with the globals.
- Made sets compute individually on demand. This should reduce the
overhead of large unneeded sets.
- Added "sets" plug to source nodes, to allow set membership to
be defined at creation time.
- Optimised SetFilter hashing.
- Prevented wildcards from being used in the Set node (#1307).
- Made Parameters node compatible with subclasses of Light/Camera/ExternalProcedural,
such as those used internally at IE.
- Shader node now adds "gaffer:nodeColor" entry into the blind data
for the shader in the scene - this allows UI components to display
the colour as appropriate.
- Added AttributeVisualiser node. This applies an OpenGL shader to
visualise the values of attributes and shader assignments.
Appleseed
-----------------------------------------------------------------------
- Fixed typo in AppleseedOptions plug names.
Documentation
-----------------------------------------------------------------------
- Improved doxyen documentation configuration.
- Documented all GafferScene nodes.
- Documented all GafferOSL nodes.
- Documented all GafferRenderMan nodes.
- Documented all GafferArnold nodes.
- Added support for Arnold "desc" metadata items.
API
-----------------------------------------------------------------------
- Refactored Node UI to provide all features via the PlugLayout and
Metadata entries.
- Added support for a "fixedLineHeight" metadata entry in
MultiLineStringPlugValueWidget.
- Added support for "layout:section" metadata - this allows the
layout to be split into sections, and will provide the basis for
replacing the Sectioned* widgets, adding support for sections in
the UIEditor, and replacing the section management code in the
StandardNodeUI.
- Added support for Metadata activators - these allow the editability
of a plug to be driven by the values of other plugs.
- Added support for section summaries driven by Metadata.
- Deprecated SectionedCompoundDataPlugValueWidget.
- Deprecated SectionedCompoundPlugValueWidget.
- Improved layoutOrder() API. It now returns the ordered plugs
for a specific parent, rather than accepting a possibly unrelated
list of plugs.

layouts.
- Reimplemented StandardNodeUI using PlugLayout.
- Fixed ExecutableNode::requirements() binding.

of the MultiLineTextWidget.
- Fixed support for functools.partial( classMethod ) commands in
Menus.

derived class bindings to base their own `repr()` implementation on
the ValuePlug one.
- Made TypedObjectPlug compatible with instantiation for new types
outside of Gaffer. This is achieved by moving the implementation into a
.inl file which may be included as necessary. Added TypedObjectPlugClass
to simplify binding such instantiations.
- Implemented PathMatcherData::hash().
- Added GafferScene::PathMatcherDataPlug.
- Reimplemented SceneNode sets API.
- Added GafferUI.LazyMethod for deferring widget method calls until
