update release gpg info.
move on.
add todo
new feature: allow different models for subrendering
integration.wtf_service:
  - added "content_type" parameter to render functions
  - added text template load/render functions
  - fixed doc strings (c&p errors)
- Explicitly ignore ModelMissingError exceptions in the prerender wrapper,
  when calling the user adapter.

- Minor interface change: render methods and scopes can be explicitly set
  to None, which avoids triggering errors, if they are required.

- Added option to model adapters to not silently ignore missing scopes
mute pylint
- Explicitly pass encoding to prerender and overlay filter processing.
  This is mostly relevant for templates, which remove the encoding marker
  (text templates do that by default).

- Fixed the problem that overlay inspection didn't work together with
  overlay filters
- refine changelog wording
integration.wtf_service:
  - add require_scopes and require_methods config options
  - move the content_type arguments to the correct functions
  - automatic content-typing is disabled now if the passed content type is None
- Add autoupdate callback registry
  (AutoUpdate.register_autoupdate_callback())

- Fix reload APIs of the AutoUpdate wrapper (updated_available() and
  reload())
maintain todo list
- autoupdate callbacks need to be passed on
- fix changelog wording
- factor out template tree preparation as a hook
- add "force" parameter to reload()
improve naming and documentation
- add generic template wrapper class
- cleanup a few comments
integration.wtf_service:
  - add single file loaders (without overlay filters)
add dependency graph class with accompanying exceptions
- Add new tool collection: tdi.tools.template. It contains functions for
  automatic template discovery and ordering by inspecting overlay
  information

integration.wtf_service:
  - renamed single file loaders to: *_file.
  - Added DirectoryTemplateLister class. An instance of this class
    can be created by the global service's .lister() method.
