June 2025 monthly summary: Focused on delivering AI-assisted editor enhancements to accelerate coding and triage, and ensuring reliability of public release data. Key features include AI-powered code actions with Fix with AI and Explain with AI, improved AI chat widget usability, and exposure of editor diagnostics to AI interactions. A README was added for the ai-editor package to improve adoption and onboarding. On the website, we fixed release data accuracy for GLSP and Sprotty by updating Releases.js to reflect correct version numbers and module information. These changes collectively improve developer productivity, reduce mean time to resolve issues, and strengthen trust in public release data. Technologies demonstrated include AI-assisted code actions, diagnostics context propagation, UI/UX improvements for AI tooling, and static data governance in the site's release pages.
