0.54.1.0
Features
Orientation : Added new node for converting between different orientation representations (eulers, quaternions, matrices etc). This is particularly useful when preparing points for instancing (#3328).
Improvements
ShaderAssignment : Added support for assigning OSL shaders with an alternative prefix. This can be useful when mixing OSL shader assignments with renderer-specific shader assignments (#3334).
Fixes
API
Improved support for iterating over nodes and plugs (#3341) :
Added FilteredChildRange and FilteredRecursiveChildRange classes. These can be used with C++11’s range-for.
Added Iterator, RecursiveIterator, Range and RecursiveRange type aliases to all nodes and plugs.
Added InputIterator, OutputIterator, RecursiveInputIterator, RecursiveOutputIterator, InputRange, OutputRange, RecursiveInputRange and RecursiveOutputRange type aliases to all plugs.
Exposed Range classes to Python.
