Mar 1, 2025During March 2025, Koski delivered measurable improvements in data accuracy, user messaging, and system stability. Key features included a recalculation of end-of-compulsory-education dates for students moving abroad (with a new SQL CTE to track move dates and updated tests, including edge cases when the move occurs before age 7). We also refined the handling of Maksuttomuus/Maksullisuus with clearer error messaging and NULLing of fee fields when no information is provided. Additionally, we removed the oppivelvollisuustiedotFiltering feature flag to simplify code paths and queries. Finally, CI/CD and database/documentation improvements strengthened reliability, including secret inheritance, pre-built E2E images, logging/test stability, port handling, and a tightened statement_timeout, along with updated database docs and E2E test stability fixes.
