Anyone know what the gold border that surrounds the barracks level number signifies that has appeared in the version 22 release?
It signifies an Advanced building. When they activate the rest of the update, all Advanced buildings will have a gold border

Just to expand on this, gold borders help tell the Advanced Buildings level 1 to 10 from other buildings Level 1 to 20.
Rumor from Beta says Advanced Buildings kept hiding among your other buildings before the border.
Converting
Conversion double arrow icon is gold if converting to an advanced building is an option ( enough iron ).
Conversion double arrow icon is red if converting back to a regular building ( available builder ).

Has it always been like that? 
No, it’s new in V22. I’m guessing all advanced buildings will have the golden border so they can be distinguished from the regular buildings.

General question: I got new update installed but cannot upgrade stronghold yet (which is correct for sure until all got upgrade) but how can people ask such questions and sent such screenshots, when they should also not be able to upgrade anything further than level 20?
What do I miss?
I think ios version must come out before we can start developing our strongholds to level 21.
I just updated my IOS version, and can’t upgrade it
They will add the ability to upgrade after everyone installed the update.

You can upgrade after your stronghold got the upgrade to level 21 and this is still not possible atm
That means it is an advanced building. Part of v22 release

It’s a new feature in v22. Barracks are considered an “advanced building”. Version 22 introduces more advanced building and that’s the way to distinguish them from “base” buildings.
Thanks for the info
