Version 0.73.0

• Implemented connection hiding for the NodeGraph. This is accessed by right clicking on a node in the Node Graph and using the new "Show Input Connections" and "Show Output Connections" menu items (#429).
• Fixed const correctness of GraphGadget::getNodePosition().
• Fixed connection drag bug. Dragging the endpoint of a connection around and then placing it back where it started was breaking the connection, whereas it should have been having no effect.
• Replaced Enabled/Disable node menu item with Enabled checkbox.
• Added titles to the node graph context menus.

Version 0.72.2

• Fixed Box creation with nested connected plugs. This allows the creation of Boxes with shader nodes with input connections.
• Fixed removal of nodules from nodes in the graph ui when Plugs are removed.
• Fixed InputGenerator bugs and added python bindings and tests.
• Fixed Group bugs involving dynamically generated inputs and undo (#179, #210, #302).
• Tidied up node menu labels.
• Renamed WriteNode to ObjectWriter and ReadNode to ObjectReader (#17).
• Fixed minimum height of ramp editor (#445).
• Fixed empty messages from ErrorDialogue.ExceptionHandler.
• Added popup error dialogues for file save failures (#449).
• Fixed context used by interactive render nodes.

Version 0.72.1

• Updated PySide build.
• Fixed bug expanding objects in viewer when a custom variable was needed by the computation (#438).
• Fixed boxing of RenderMan coshaders (#440).
• Fixed Qt 4.6 compatibility.

Version 0.72.0

• Added workaround for weird focus-stealing behaviour in Maya.

• Added application variable to the scope available to the screen grab command.

• Added support for empty and relative paths in Gaffer.Path. ( #432, #324 )

  • Added root parameter to all path constructors. This is used to define the root when the path parameter is passed a list of items. Because python doesn't allow overloaded functions this is slightly awkward - see documentation of Path.init for discussion of how this would break down into overloaded constructors when we move the implementation to C++.
  • Added Path.root() and Path.isEmpty() methods.
  • Added Path.setFromPath() method, which copies the elements and the root from another path. This should be used in place of code which formerly did path[:] = otherPath[:].

  Note that the new root parameter changes the parameter order for all Path (and derived class) constructors - if you were formerly passing a filter as a non-keyword argument you should now pass it as a keyword argument to avoid problems. Additionally, if you implemented a custom Path subclass, you need to add the root parameter to your constructor and update your copy() and children() implementations. The DictPath changes provide a minimal example of what needs changing.

Version 0.71.0

• Variable substitution improvements
  • Added standard ${script:name} variable (#407)
  • Added custom script-wide variables accessible via the File->Settings menu (#407)
  • Added support for variable references within variables (recursive substitution)
  • Added environment variable and ~ substitution
  • Added standard ${project:name} and ${project:rootDirectory} variables.
• Fixed save and load of ReadOnly plugs.
• Removed Escape hotkey for leaving full screen mode. The same function is served by the ` hotkey.
• Defined default locations for ribs, ass files and rendered images.
• Added automatic directory creation for display, rib and ass locations (#59)
• Added GraphComponent::clearChildren() method
• Greyed out File->RevertToSaved menu item when it doesn't make sense
• Improved CompoundDataPlug data representation
• CompoundPlugValueWidget using PlugValueWidget.hasLabel() to avoid unecessary labelling
• Fixed UI for promoted plugs (#264)
• Fixed bug where deleted children of Boxes weren't removed from the selection (#430)
• Fixed bug where pinned nodes were still visible in the UI after being deleted (#308)
• Fixed hangs caused by adjusting colours while rerendering
• Tidied up some test cases

Version 0.70.0

• Added Ganging for CompoundNumericPlugs (#402)
• Added menu item for loading renderman shaders from file (#125)
• Added color ramp editing support (#286)
• Added spline parameter support to RenderManShader::loadShader()
• Added shader annotations for passing default values to RenderManShader splines
• Added dividers in the NodeEditor, available to RenderMan shaders via the annotation "parameterName.divider" (#288)
• Added API for undo merging.
• Added ScriptNode::undoAddedSignal() (#103)
• Fixed hiding of Menu when using the search box
• Fixed tab focus ordering in NodeEditor (#107)
• Improved GadgetWidget focus behaviour (#119)
• Fixed redundant CompoundNumericPlug serialisation (#2)
• Fixed scrubbing of values for IntPlugs
• Fixed size issues caused by TabbedContainer size policy (Settings and About window)
• Fixed bug in Random::affects()
• Fixed multiple undo entries in virtual sliders, cursor up/down nudging, color choser, and ramps (#400)
• Fixed Ctrl+C copy shortcut in non-editable MultiLineTextWidgets
• Hid Shader enabled plug in the UI (#398)
