NEXUS POS 19.10.3 — BOOKSHOP SAME-TAB RECEIPT PRINTING
Runtime: 20261019.275
Base runtime: 20261019.274 (Phase 19.10.2)

LOCALHOST UPDATE:
1) Backup existing Nexus files and database.
2) Extract LOCALHOST UPDATE ZIP over the existing Nexus root (the folder containing bookshop/).
3) Refresh Bookshop POS (Ctrl+Shift+R), complete and print a test ETR sale, then A5.
4) Print a credit repayment and reprint a sale from POS history.
5) Confirm the actual receipt feeds out on-screen, then the browser print dialog opens while the POS remains in the same tab.

FULL LOCALHOST:
Use FULL LOCALHOST ZIP for a clean Phase 19.10.3 install. It is the complete Phase 19.10.2 project with the same-tab print enhancement, not a Phase 19.11 / 19.13 cumulative upgrade.

PRODUCTION:
Only apply the PRODUCTION UPDATE ZIP over Phase 19.10.2 through Super Admin → Updates. The package excludes config/database.php and credentials. Test on localhost and back up production first.

No database changes. Browser print confirmation is not bypassed.
