Apr 1, 2026April 2026 monthly summary for grafana/grafana focusing on delivering high-value onboarding and editor improvements, backed by robust tests and UI polish. Key features delivered include Splash Screen enhancements with versioned dismissal persistence, OSS-flag enabled by default, role-based CTAs with UTM tracking, and accessibility improvements, all accompanied by unit and e2e tests. End-to-end coverage was expanded for QueryEditorNext with Playwright tests and a multi-select feature toggle, increasing reliability of critical user workflows. Transformations and dashboards saw stability gains through promoting Time series to table to GA, added dashboard transformation smoke tests, and UI refinements such as replacing a clipped add-panel image with scalable SVG. UX improvements in PanelEditNext moved the query inspector to the footer, and broader small-screen layout fixes and accessibility improvements contributed to higher quality experiences. This work drives business value via improved onboarding, better analytics attribution, reduced risk in releases, and stronger developer productivity through shared test infrastructure and cleaner UI and UX.
