6.1The Release Trajectory (What to Know, Version by Version)
You don't need to memorize changelogs, but the 2025→2026 arc tells a story interviewers respect — the world's most-used web test framework re-architecting itself around agents:
| Version | Agent-relevant change |
|---|---|
| 1.56 | Test Agents introduced (planner / generator / healer), npx playwright init-agents |
| 1.59 | browser.bind() — agent, test runner, and MCP server share one browser instance; Screencast API |
| 1.60 | HAR capture folded into tracing; Drop API |
| 1.61 (current, Jul 2026) | WebAuthn passkey testing, Web Storage APIs |
Two of these deserve a closer look.
