   It contains all required intervening 19.10 Bookshop/Agrovet files.

Back up production files and databases first. Do not use a full localhost package for production. Do not manually lower the min_runtime or replace config/database.php. Verify the preview's starting and target runtimes before installing.

After installation, refresh cached assets, test ETR/A5 same-tab printing, Luna sale preparation with a test user, Savings, and Super Admin announcements.

There is no manual SQL migration. Physical printer testing is required.
