Apr 1, 2026Summary for 2026-04: In kivitendo/kivitendo-erp, delivered a cohesive set of features, fixed critical bugs, and advanced localization and workflow reliability. Key feature work strengthened Contacts as first-class citizens (JS-driven Controller-Actions and commit_one helper), improved UI consistency and keyboard navigation across Pickers (Charts, CustomerVendor, Projects) with Delete/Clear, and enhanced delivery/invoicing workflows by preserving billing_address_id in delivery orders. Localization received a major push with Druckvorlagen mersiha translations and naming improvements, and Countries localization/refactor with tests and docs. Major bugs resolved included the Contacts Presenter, pre-filled ContactPicker, and import/Wiedervorlagen/CSV-related issues, along with UI visibility fixes in table headers and clearer bankimport error messaging. The overall impact is improved data integrity, smoother user experience, and a more globally ready platform, enabling faster onboarding, accurate invoicing, and scalable localization. Technologies demonstrated: JavaScript-driven controller actions, advanced UI alignment and keyboard handling, template state preservation, code quality improvements, and comprehensive localization/testing coverage.

Feb 1, 2026February 2026 highlights for kivitendo-erp: Delivered significant data integrity, concurrency, and UX improvements, with targeted fixes and performance optimizations that enhance reliability and business value. Key features include database integrity and concurrency improvements using ROW EXCLUSIVE locks on session content and the TransNumberGenerator, along with safeguards to prevent errors when IDs are missing during sales removal. Follow-up lists loading was optimized to trigger only in popup mode, reducing unnecessary data retrieval and boosting UI responsiveness. UI/UX enhancements and localization fixes were rolled out (default search profile for purchase invoices, corrected German translations, and fixed typo in accounts payable search). Release notes were updated to reflect CAMT.053 bank import experiments and to ensure accurate release entries for connected customers/vendors. A dedicated workflow check was added for missing IDs in the Lieferschein-to-Rechnung flow. Business value realized includes improved data integrity, reduced deadlocks, faster UI, and better release documentation.
