[Qgis-developer] Broken models with processing (i.e we shouldn't be doing that)

[Victor Olaya]

Hey Nathan

I agree with you, and I have been wanting to do this...but it requires some
work, since not only the format has changed, but also the inner structure
of the models. Unfortunately, I am not having too much time to work on
Processing lately, but I guess it will be ready for the next release. I
would be a pity to ship QGIS with the older version, since this new one has
plenty of improvements and good new things

Thanks for the advice!
