     - Follow the writing the [Cypress Changelog release steps](./writing-the-cypress-changelog.md#release) to update the [`cli/CHANGELOG.md`](../cli/CHANGELOG.md).
 
 4. Once the `develop` branch is passing in CI and you have confirmed the `cypress-bot` has commented on the commit with the pre-release versions for `darwin-x64`, `darwin-arm64`, `linux-x64`,`linux-arm64`, and `win32-x64`, publishing can proceed.

+     - If the `windows` workflow is failing with timeout errors, you can retry from the last failed step.
+     - Sometimes a test can get stuck in a failing state between attempts on the `windows` workflow. In these cases, kicking off a full run of the workflow can help get it into a passing state.
+     - If the `linux-x64` workflow fails due to a flaky test but percy finalizes the build, you *must* restart the workflow from the failed steps. Restarting the entire workflow after a finalized Percy build can cause Percy to fail the next attempt with a "Build has already been finalized" error, requiring pushing a new commit to start fresh.
 
 5. Log into AWS SSO with `aws sso login --profile <name_of_profile>`. If you have setup your credentials under a different profile than `prod`, be sure to set the `AWS_PROFILE` environment variable to that profile name for the remaining steps. For example, if you are using `production` instead of `prod`, do `export AWS_PROFILE=production`.
