Pymel

==================================

----------------------------------
Changes
----------------------------------
- default testing engine changes to pytest (from nose)
- remove ply as requirement, as we have pymel.util.external.ply
- utilitytypes: make LazyLoadModule a class, not func

----------------------------------
Additions
----------------------------------
- added support for 2018
- system: add FileReference.nodes(recursive=True) flag
- Adding pm.isModified function (replacement for cmds.file(q=1, modified=1)
(thanks, bob-white!)
- Added file reference remove flags (thanks, wesbondie!)
- added mergeNamespaceWithParent and mergeNamespaceWithRoot to
FileReference.remove to match docs (thanks mjmvisser!)
- add kwargs support to getClassfication - issue 343 (thanks kartikg3!)
- plugins: add FileTranslator plugin helper base class to pymel.api.plugins
- util.enum: add Enum.itervalues
- maintenance: make stub generation more general-purpose; add cli
- stubs: improvements to PEP484 pyi stub file generation
- tests support pytest now

----------------------------------
Bug Fixes
----------------------------------
- fix for Attribute equality for compound multi attrs
- cmds.file(new=1, type='mayaAscii') will crash maya - pm.newFile() will now
automatically ignore any type/typ flags to avoid this - issue 346
(thanks bob-white!)
- fix for mesh.numTriangles() raising a TypeErorr - issue 388
(thanks kartikg3!)
- fix for uitypes.Menu.getItemArray exceptions (thanks bob-white!)
- plogging: fix for setting of root logging level (thanks sdalgo!)
- fix to deal with nodes showing up multiple times in inheritance tree from
cmds.nodeType (ie, aiSkyDomeLight)
- ipymel now working again with modern versions of IPython
- fix for PyNode becoming invalid if instance is reparented in some situations
- deprecated api-wrapped functions weren't returning values
- dynamically create PyNodes from nodetypes - fixes issue with some maya node
types that can't get detected on plugin load
- fix for hasParent/hasChild/isParentOf/isChildOf with underworld nodes
- pm.parent will set PyNodes fed in to use the correct instance / parent
- better fix for mayapy segfaults (run maya.standalone.uninitialize)
- factories: some functions using MFloatPoint weren't doing unit conversion
- some node types that are dag nodes don't work with MFnDagNode - however,
.nodeName() should still work (as that doesn't need MFnDagNode)
- nodetypes: attempt to deal with crash with instances;
get it when you add an instance of an object, and then access the old object;
this doesn't completely solve the issue, but it may be impossible to avoid
completely without a patch for the underlying problem from autodesk
- fix for pm.listNamespaces() returning duplicates weed out - issue 380
(thanks mjmvisser!)
- datatypes: fix to deal with new swig-generated setattr in 2018
- factories: fix for fromInternalUnits with ref-casts
- factories: fix for isMayaType, for weird types
(ie, TadskAssetInstanceNode_TdependNode, which is a parent of adskMaterial)
- factories: prefer non-deprecated api methods
- startup: fix some hangs on exit in maya 2016.51
- pymel.conf: fix name of fix_linux_mayapy_segfault
- stubs: fix for detection of os.environ

==================================

==================================

----------------------------------
Non-Backward Compatible Changes
----------------------------------

----------------------------------
Bugfixes
----------------------------------

- general: for the keyframe command, the upper / lower limits substituted in for the "index" flag, when no upper/lower limits were given, are now correct; formerly, the behavior of index=":" would vary depending on where (in time) the first and last keyframes were
- general: timerange flags (ie, keyframe(time=...), findKeyframe(time=...), etc) now provide correct results when no upper/lower limits given; formerly, the time=":" would vary depending on if / which objects were selected

- nodetypes: Container.getParentContainer, Container.getRootTransform, and Character.getClipScheduler now all return None instead of raising a runtime error if no object was found
- system: FileReference.fullNamespace and iterReferences/listReferences with namespaces=1 now handle situations where reference node itself is in a non-root namespace correctly
- general: when instantiating PyNode from an MPlug, to get the PyNode for the node, create from the underlying mobject, not the name (which may not be unique)
- animation: fix for Joint.getAngleX/Y/Z, .getStiffnessX/Y/Z; joint.radius no longer returns list
- mel2py: numerous fixes / tweaks
- system: handle situations where reference node itself is in a non-root namespace

- general: cmds.group returns unique name in maya > 2014
- fix for virtual classes
- versions: parsing for 'Preview Release' format - from Dean Edmonds

==================================

==================================

----------------------------------
Non-Backward Compatible Changes
----------------------------------

- DagNode.isVisible: has a new flag, checkOverride, which is on by default, and considers visibility override settings
- referenceQuery/FileReference.getReferenceEdits: if only one of successfulEdits/failedEdits is given, and it is false, we now assume that the desire is to return the other type (and set that flag to true); formerly, this would result in NO edits being returned
- parent no longer raises an error if setting an object's parent to it's current parent; this makes it behave similarly to the mel command, and to DagNode.setParent
- renameFile now automatically sets the 'type' if none is supplied (helps avoid renaming a file to 'foo.ma', then saving it as 'mayaBinary')
- general: 1D components have index() method: can no longer use string.index()
