Hello,
The Squared theme for Moodle 3.5 to 3.7 has been updated as follows:
- M3.5 3.5.1.0: https://moodle.org/plugins/pluginversion.php?id=19872
- M3.6 3.6.1.0: https://moodle.org/plugins/pluginversion.php?id=19873
- M3.7 3.7.1.0: https://moodle.org/plugins/pluginversion.php?id=19874
The theme is now a child theme of Boost and has been updated therefore to BS4 (version thereof within the given Moodle version).
If you encounter any issues with these versions 'only' then please reply here.
Cheers,
Gareth
