June 2026 monthly summary for PrestaShop/autoupgrade: Implemented an idempotent upgrade migration to set PS_SHOP_MODE to the default 'b2c_only' during PrestaShop 9.2.0 upgrades, aligning existing shops with fresh-install defaults and reducing post-upgrade support. The migration uses add_configuration_if_not_exists to avoid overwriting existing configurations, ensuring safe, repeatable upgrades across environments. Business value: more reliable upgrades, consistent behavior, and lower support overhead; Technical: robust PHP migrations, configuration API usage, and safe migration patterns.

Month 2026-05 Summary: Implemented flexible Business Identifier support by making id_zone nullable across the business_identifier data models in both core and upgrade tooling. Completed core schema and ORM updates to support non-geographic identifiers, and aligned upgrade SQL with the revised B2B data model. Also updated configuration and testing workflows to ensure reliable data entry and migrations. This work improves data entry flexibility, data integrity, and future-proofing for business identifiers, with clear traceability across repository changes.
