What's Changed

This release addresses the v91 (ESR) Thunderbird stable branch.

⚠️
Due to upstream sections "namespace" changes, mail-related preferences sections have been shifted from 6000 / 6100 / 6200 / 6300 to 9100 / 9200 / 9300 / 9400.
You are advised to reinstall from scratch the template and append your preferences overrides on top of it.
