Jul 1, 2026July 2026 metasfresh monthly summary: Delivered a key date-handling standardization in the Metasfresh project by migrating earliestLineDatePromised from java.sql.Timestamp to ZonedDateTime. This aligns with modern Java time API and ensures consistent date-time handling across order processing (OLCand.getDatePromised), improving maintainability and reducing timezone-related risks.

May 1, 2026May 2026 monthly summary for metasfresh/metasfresh: Key features delivered include Mobile QR Scan UX improvements with localized error messages via MobileQRCodeMessages, centralizing error handling and replacing raw messages with localized, actionable text. This work also wired DistributionHUService.assertHUCanBePickedFrom to enforce correct HU workflow and introduced data/backfill migrations. A migration (5803900) added 15 new AD_Message records and backfilled missing error codes for three existing messages. Expanded E2E test coverage for distribution scan-HU barcodes and inventory error scenarios to validate end-to-end flows. In parallel, improved reliability of the picking process by refactoring error handling to fix unreliable toast notifications and removing unused variables. Overall, this work enhances user experience on mobile, strengthens localization and error handling, improves HU/picking correctness, and raises testing coverage and data quality.
