15.19.0: TypeScript 7 support and fewer browser crashes
ReleasedReleased on July 21, 2026
Cypress now supports TypeScript 7 when preprocessing spec and support files, and the component testing setup wizard accepts it too. This release also fixes several causes of browser crashes and memory growth, a ResizeObserver renderer crash, a leak that accumulated across long specs, and cy.press() memory retention, so long, command-heavy runs stay stable. New assertion aliases (.exists, .greaterThanOrEqual, .lessThanOrEqual) round it out.
