pyramid_openapi3 is getting a bit stale (8 months of no changes on master). We need to cap a lot of libraries in its dependency tree.
They (pyramid_openapi3 and any project from python-openapi github org) don't follow semantic versioning, so I'm limiting them to PATCH versions only. We can't trust MINOR version updates.
