Changement de rupture de WTForms 2.3.0 - ImportError: impossible d'importer le nom 'HTMLString' depuis 'wtforms.widgets'

WTForms a été mis à jour en 2.3.0 avec un changement de rupture. J'ai essayé d'ajuster d'autres exigences telles que werkzeug.1.0.0 mais pas encore de chance. Est-ce que quelqu'un a trouvé une solution?

Voici la séquence de pile:

En plus de la réponse de JBLaf, HTMLString a été remplacé par Markup. Alors utilisez from markupsafe import Markup au lieu.

from wtforms.widgets.core import escape_html a également été remplacé par from markupsafe import escape

Dans WTForms 2.3.1 ces termes sont rajoutés en tant qu'alias et un avertissement d'obsolescence est affiché au lieu d'un changement de rupture.
