Where can I find a list of breaking API changes for each release.

Support

…The release notes does not seem to include these details.
For example
vtkGenericOpenGLRenderWindow::SetBackBuffer (VTK: vtkGenericOpenGLRenderWindow Class Reference)
no longer exists in the latest version of vtkGenericOpenGLRenderWindow
(VTK: vtkGenericOpenGLRenderWindow Class Reference)
What is the workaround for applications needing to use SetBackBuffer ?

vtkGenericOpenGLRenderWindow::SetBackBuffer was removed between VTK 8 and VTK 9, a major version change, which may explain why it was not deprecated.

In any case, just use SetLeftBackBuffer instead
