ImageStats : (#2018)
Defaulted to sampling A in addition to RGB.
Changed interpretation of ImageStats channels to simply be a list of 4 channels that correspond directly to the output RGBA plugs. Behaviour is unchanged apart from situations where an incomplete or ambiguous channel mask was in use.
Warp : New API (#1980).
Engine no longer depends on channelName.
Derived classes no longer responsible for computing inputWindow.
Renamed UndoContext to UndoScope (#2049).

Removed ChannelMaskPlug. Use a StringPlug and

Stats app : Added performance monitor summary (#2016).
Merge : Added min and max modes (#2027).
Grade : Added support for grading alpha channel (#2023).
Warp : Improved filtering (#1980).
Added more string matching features #2015 :
[A-Z]style character classes
?to match any character
‘’ to escape a subsequent wildcard
Added mode and units settings to the UVWarp node, and renamed it to VectorWarp (#2014).
StandardNodeGadget : Added more metadata support (#2011)
“icon” to add an icon.
“nodeGadget:shape” to choose a rectangular or oval shape
Shader : Fixed bug when assigning a disabled shader with pass-through defined (#2025).
OSLCode : Fixed string length menu item (#2039).
ErrorDialogue : Fixed bug in message handling code (#2030).
StringAlgo : Fixed bug in
Switch/Dot : Fixed plug colours in NodeGraph (#2008).
Transform/Resize : Fixed sinc filter (#1980).
Fixed export of color/vector plugs from Boxes (#2012).
Resize : Stopped resampling when only pixel aspect ratio is changed (#2007).
Fixed crash in viewport mouse handling (#2005).
Fixed Node Reference link in help menu (#2002).
Fixed framing of lights in the Viewer, by giving them a default bounding box (#2054).
Added “childNodesAreReadOnly” metadata. This makes it possible to make the internal nodes of a node read-only, while still allowing the external plugs of the node to be edited (#2048).
Added functions for bookmarking nodes (#2039).
childAffectedByChange()overload for Node changes (#2029).
NoduleLayout : Added support for custom Gadgets to be specified via metadata (#2043).
Context management (#2041, #2016) :
Added Context::EditableScope utility class. Use this instead of the now-deprecated Context::Borrowed copy contructor.
Added PathScope/SetScope/GlobalScope utility classes to ScenePlug
Added GlobalScope/ChannelDataScope utility classes to ImagePlug.
Added FilterPlug::SceneScope utility class.
Added V2iVectorDataPlug (#2031).
