# 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.
