# 15.17.0: Faster debugging in long tests, plus Bun support

ReleasedReleased on June 9, 2026

The Command Log no longer becomes unresponsive when hovering over a test's command list during long runs, and a memory leak affecting screenshot-on-failure runs is fixed, so CI runs no longer slow down as failures accumulate. Bun is now a supported package manager: `bun run cypress open` and `bun run cypress run` work out of the box.
