Feb 1, 2026February 2026 (2026-02) monthly developer summary for espoon-voltti/evaka. Focused on delivering measurable business value through a combination of data reliability, security hardening, and streamlined data fetch paths. Key outcomes include migrating data fetching and result wrapping to React Query across core modules (messages, units, finance, and miscellaneous/mobile/Nekku reports), which improves data freshness and reduces flicker. A targeted code refactor merged getSecondaryUser and isSecondarySessionNewer to reduce duplication and improve maintainability. The income statement workflow was enhanced with a new status and validations, including filter validations. Security and observability were strengthened via OWASP suppression for CVE-2026-24734, username sanitization, and error reporting in catch blocks. Several reliability fixes were released to improve data integrity and stability, including correct persistence of modified-at/by fields for attendance updates and fixes to voucher links and notifications. Overall, these changes enhance data accuracy, reduce risk, and enable faster, safer feature delivery for end users.
