Sep 1, 2025September 2025 focused on API modernization, documentation, and release readiness for FlexMeasures/flexmeasures. Key initiatives included refactoring the API surface to use a dedicated service layer for asset creation, patching, and deletion; redesigning sensor data endpoints to use sensor IDs in the URL and deprecating older endpoints; and consolidating user password reset logic. KPI Widgets documentation for the asset page was published, detailing configuration for daily sums, means, max/min, and the kpi_sensors_to_show field, with notes on a future graphical KPI editor. Release readiness work included dependency upgrades across Python versions and updated changelogs, API docs, and CLI notes for v0.28.0 and placeholder entries for v0.29.0. These efforts improve API consistency, reduce technical debt, and accelerate reliable releases across the product."
