There is a bunch of these deprecation warnings:

/vagrant/lib/hawat/base.py:636: DeprecationWarning: 'jinja2.Markup' is deprecated and will be removed in Jinja 3.1. Import 'markupsafe.Markup' instead.
  self.config.get('ICONS').get(default_icon)
/vagrant/lib/hawat/view/__init__.py:1846: DeprecationWarning: 'jinja2.Markup' is deprecated and will be removed in Jinja 3.1. Import 'markupsafe.Markup' instead.
  flask.Markup(self.get_message_success(item = item, parent = parent)),

Regarding the second part of this issue, I would go with the solution described at https://stackoverflow.com/questions/59680450/how-to-detect-compiler-warnings-in-gitlab-ci. It won't produce any emails but on GitLab it will be visible that there are some warnings.

I changed Flask and internal packages (Pynspect, Pyzenkit, Pydgets, Idea, TypedCols, IPRanges) to use the most up to date versions. Now the version is limited by the major version, so those packages should be regularly updated, when minor versions are released. (https://stackoverflow.com/questions/46601761/is-it-a-good-practice-to-upgrade-all-python-packages-in-production-to-their-late)

I added wtforms_sqlalchemy package to replace wtforms.ext.sqlalchemy which has deprecation warnings. (https://github.com/wtforms/wtforms-sqlalchemy)

I also fixed the broken/skipped tests (#7494), so now all of the existing tests should be executed and deprecation warnings are printed.

I didn't update the other packages (such as pytz or wtforms), as they didn't produce any deprecation warnings.

Merged into devel and deployed on mentat-alt.
