May 1, 2026May 2026 – Chap Core maintenance focused on strengthening data integrity and model reliability in the ExtendedPredictor. Delivered a targeted bug fix that preserves covariate columns when appending future data to historic data, preventing NaN features in subsequent iterations and stabilizing iterative predictions. Patch implemented in dhis2-chap/chap-core (commit 793c867b6f7374cef171541c807f5487a3caa312). Business value: more dependable analytics, fewer downstream errors, and faster model training cycles.
