Cypress 15 introduces foundational improvements aimed at enhancing stability and preparing for future advancements, including significant updates to Cypress Studio, which now allows inline test editing and lays the groundwork for AI-assisted test creation. This release removes support for outdated technologies such as older Node.js versions, Webpack 4, and Angular 17, to focus on modern workflows and better integration capabilities. Notable under-the-hood changes include a visual refresh of the Cypress Command Log, fixes for TypeScript and ESM module issues, and updates to core commands for improved resilience in cross-origin scenarios. The upgrade also introduces support for Vite 7 and Angular 20, alongside renaming and expanding certain APIs to better align with new features. Users are encouraged to upgrade to Cypress 15, enable the experimentalStudio feature, and explore early access to upcoming AI-assisted capabilities.
