There's a merged pull request on the void-packages repository python(3)-Flask-WTF: update to 0.14.3 https://github.com/void-linux/void-packages/pull/22028 Description: Apparently werkzeug recently went 1.0 and removed some deprecated imports, which Flask-WTF [fixed](https://github.com/lepture/flask-wtf/commit/8b028994b68f5fffbf920770a0b4943a5225b282) and included in this release (from three months ago...). I only noticed because of the shiny new etesync-dav package!
