is ../CHANGES is still needed/intended

[yarikoptic]

error message is spit out (and ignored) while building docs,

> /<<PKGBUILDDIR>>/nipype/sphinxext/plot_workflow.py:docstring of nipype.sphinxext.plot_workflow.ImageFile:18: WARNING: toctree references unknown document u'api/generated/nipype.sphinxext.plot_workflow.ImageFile.filenames'
> /<<PKGBUILDDIR>>/doc/changes.rst:9: WARNING: Problems with "include" directive path:
> InputError: [Errno 2] No such file or directory: '../CHANGES'.
> /<<PKGBUILDDIR>>/doc/devel/interface_specs.rst:474: WARNING: Bullet list ends without a blank line; unexpected unindent.
> /<<PKGBUILDDIR>>/doc/devel/testing_nipype.rst:93: WARNING: Unexpected indentation.

which confuses/complicates analysis of actual error leading to failed build e.g. https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=917740 . So I wondered if it is still intended to be used or replaced fully by those changelogs per version and thus include should be fixed up?:

$> git grep CHANGES
...
doc/changes.rst:.. include:: ../CHANGES
...
tools/update_changes.sh:CHANGES=../doc/changelog/1.X.X-changelog
