September 2025 — Grafana K6 Studio: Stability improvements for the custom code editor. Implemented a bug fix addressing crashes when pasting content by ensuring the editor's internal model is synchronized with the provided value before applying constraints, and by updating the effect hook dependencies to include the value prop so content changes re-trigger effects and prevent data inconsistencies. The changes were committed to grafana/k6-studio (commit 37ca9615af11efdc71288a0f5b6bb73bc69d4505).
