@RedEight: did you encounter any issues be changing base theme to stable9? I am this month in the process of migrating to Drupal 10.

The contrib version of 'Stable' theme also seems to work. I haven't completed an upgrade to D10 to see how that goes, but Upgrade Progress report is happy.

Is there a good reason why in the latest 5.2 release a dependency was added to the contrib stable project instead of using stable9 which is shipped with Drupal 10.x?

I did not experience any incompatibilities on my sites with stable9 but maybe there are?

Personally, I prefer using as few contrib code as possible...

hi,
go to /themes/contrib/adaptivetheme/at_core
edit at_core.info.yml

base theme: stable9
dependencies:
- stable9:stable9

and check in subtheme info file;
core_version_requirement: '^9.3 || ^10'
