In pqAddToFavoritesReaction, the constructor pqAddToFavoritesReaction(QAction* parent, QVector<QString>& filters) has been removed. Favorites are now integrated into Categories, and should be initialized from a pqProxyCategory instead.
In pqCategoryToolbarsBehavior, the slot void prepareForTest() was removed as it was unused.
In pqColorMapEditor, the slot void setDataRepresentation(pqDataRepresentation* repr, bool forceUpdate = false) was removed. Use setRepresentation() instead.
In pqDataAssemblyPropertyWidget, the properties selectorColors, compositeIndexColors, selectorOpacities, and compositeIndexOpacities and their associated accessors and signals have been removed.
In pqLiveSourceBehavior, the static member functions void pause(), void resume(), and bool isPaused() have been removed. Use functions of the same name in pqLiveSourceManager instead.
Class pqManageFavoritesReaction has been removed. Favorites should be replaced by Categories configuration. See pqConfigureCategories instead.
In pqProxyGroupMenuManager, vtkSMProxy* getPrototype(QAction* action) const has been removed in favor of static vtkSMProxy* GetProxyPrototype(QAction*), bool hideForTests(const QString&) const and void setEnabled(bool) have been removed because they were mostly unused, void populateFavoritesMenu(), void loadFavoritesItems(), and QAction* getAddToFavoritesAction(const QString& path) have been removed because favorites are now a category configurable like other categories, and the protected Enabled member variable has been removed because it is unused.
Class pqFavoritesDialog and its associated Qt .ui file have been deleted.
Class pqQuickLaunchDialog has been removed. Please use pqQuickLaunchDialogExtended instead.
Class pqWaitCursor has been removed. Please use pqScopedOverrideCursor(Qt::WaitCursor) instead.
In vtkSMAnimationScene, member function void SetDuration(int) has been removed. Use SetStride(int) instead.
In vtkInitializationHelper,
- Member function static bool InitializeMiscellaneous(int) has been removed. Use InitializeSettings() and InitializeOthers() instead.
- Member function static std::string GetUserSettingsDirectory() has been removed. Use vtkPVStandardPaths::GetUserSettingsDirectory() instead.
- Member function static std::string GetUserSettingsFilePath() has has been removed. Use vtkPVStandardPaths::GetUserSettingsFilePath() instead.
In vtkGeometryRepresentation, member function virtual void SetFlipTextures(bool) has been removed. Use SetTextureTransform() instead to flip a texture.
In vtkPolarAxesRepresentation, accessors for EnableCustomRadius have been removed. Use accessors for EnableCustomMinRadius instead.
In vtkSMColorMapEditorHelper, member function static vtkSMProxy* GetLUTProxy(vtkSMProxy*, vtkSMProxy*) has been removed and replaced with GetLookupTable(vtkSMProxy*, vtkSMProxy*).
In vtkSMPVRepresentationProxy,
- Member function void SetLastLUTProxy(vtkSMProxy*) has been removed and replaced with SetLastLookupTable(vtkSMProxy*).
- Member function vtkSMProxy* GetLastLUTProxy() has been removed and replaced with vtkSMProxy* GetLastLookupTable().
- Member function vtkSMProxy* GetLUTProxy(vtkSMProxy*) has been removed and replaced with vtkSMProxy* GetLookupTable() instead.
In vtkPVGeometryFilter, the following information keys have been removed because they were not used:
- static vtkInformationIntegerVectorKey* POINT_OFFSETS()
- static vtkInformationIntegerVectorKey* VERTS_OFFSETS()
- static vtkInformationIntegerVectorKey* LINES_OFFSETS()
- static vtkInformationIntegerVectorKey* POLYS_OFFSETS()
- static vtkInformationIntegerVectorKey* STRIPS_OFFSETS().
Also in vtkPVGeometryFilter, member function void CleanupOutputData(vtkPolyData* , int) has been replaced with void CleanupOutputData(vtkPolyData*), and member function void ExecuteCellNormals(vtkPolyData* output, int doCommunicate) has been replaced with void ExecuteNormalsComputation(vtkPolyData*).

A number of filter proxies have been removed and replaced:

AppendArcLength, replace with PolyLineLength.
GenerateIds, replace with PointAndCellIds.
PolyDataTanges, replace with SurfaceTangents.
AppendLocationAttributes, replace with Coordinates.
BlockIdScalars, replace with BlockIds.
OverlappingLevelId Scalars, replace with OverlappingAMRLevelIds.
GenerateSpatioTemporalHarmonics, replace with SpatioTemporalHarmonics.
PolyDataNormals, replace with SurfaceNormals.
ComputeConnectedSurfaceProperties, repalce with ConnectedSurfaceProperties.
GenerateProcessIds, replace with ProcessIds.
