(2.0.0) — [release notes](https://github.com/flakiness/playwright/releases/tag/v2.0.0) - The supported Node.js engine range now starts at 22.9.0; Node 20 has been dropped. (2.0.0) — [release notes](https://github.com/flakiness/playwright/releases/tag/v2.0.0) - open now defaults to 'never', so the reporter prints the flakiness show command instead of launching a browser; set it to 'on-failure' to restore the old behavior. (2.0.0) — [release notes](https://github.com/flakiness/playwright/releases/tag/v2.0.0) - Balanced sharding now requires a timings file, produced with flakiness-playwright-timings build or fetch and committed, making shard splits stable across runs. (2.0.0) — [release notes](https://github.com/flakiness/playwright/releases/tag/v2.0.0) ### New APIs and options - GitLab CI/CD uploads can authenticate without an access token by declaring an id_tokens entry named FLAKINESS_ID_TOKEN with an aud matching flakinessProject.

(2.0.0) — [release notes](https://github.com/flakiness/playwright/releases/tag/v2.0.0) ### Tooling - Each shard prints timings coverage, predicted per-shard loads, and a balance percentage before the run, then the predicted-vs-actual delta after it. (2.0.0) — [release notes](https://github.com/flakiness/playwright/releases/tag/v2.0.0) ### Fixes and other changes - Improves support for serial suites. (2.0.3) — [release notes](https://github.com/flakiness/playwright/releases/tag/v2.0.3) - Fixes a corner case in the sharding algorithm.
