@dpgaspar would you mind running,

pip-compile --output-file requirements.txt setup.py

to ensure that we pull in all the updated dependencies for Flask-AppBuilder version 1.12.5? Note you may also need to bump pip-tools to version 3.5.0 in requirements-dev.txt due a related pip issue.

no problem!
