Hi folks – if you use the App Server, this one is important for you:
We’ve released Anvil App Server 1.16.0, via the usual channels (pip install --upgrade anvil-app-server or docker pull anvilworks/anvil-app-server:1.16.0).
This release fixes a schema migration issue where existing columns with explicit client_hidden: false could be treated as a delete/add column change during automatic migration.
Users on 1.15.0 should upgrade before running with --auto-migrate.
If an app has already been affected by the bad migration, upgrading will prevent the issue from recurring, but it will not restore data that was already deleted. Those apps need a backup restore or app-level recovery.
