For IT administrators managing policy changes, this release puts the focus on reviewing changes before deployment and making recovery and audit tasks more straightforward.\n\nThe release includes three updates to the policy workflow:\n\n&#8211; **Simulate policies before deployment.** Use the policy simulator to review a proposed policy before deploying it. This adds a review step ahead of deployment, rather than making a live push the first opportunity to evaluate a change.\n&#8211; **Roll back with one click.** When a deployed policy needs to be reversed, one-click rollback provides a direct recovery action. Simulation and rollback address different parts of the workflow: reviewing a change beforehand and reversing it afterward.\n&#8211; **Export audit data as CSV or JSON.** Choose between two export formats for your audit processes. Administrators can select the format that fits their existing reporting or data-handling requirements.\n\nSSO now supports Okta and Microsoft Entra ID, adding identity-provider options for teams using those services.\n\nAcross 42 beta workspaces over 30 days, beta users reduced failed policy pushes from 14% to 3%. These results reflect that beta sample and observation period; they are not a guarantee of results in your environment.\n\nBusiness and Enterprise teams can access the release today. Starter will receive a read-only version of the policy simulator next quarter.\n\nOpen the policy simulator.<\/textarea><p style=\"margin:8px 0 0;color:#4f696b;font-size:13px\">HTTP 200 \u00b7 15.47s \u00b7 165 input \u00b7 500 completion \u00b7 score 10\/10<\/p><\/div><div style=\"min-width:0\"><div style=\"display:flex;align-items:center;justify-content:space-between;gap:8px;margin-bottom:7px\"><strong>Claude Fable 5.1<\/strong><button type=\"button\" data-copy-target=\"result-f-2\" style=\"border:0;border-radius:5px;padding:7px 10px;background:#d36449;color:#fff;font-weight:800;cursor:pointer\">Kopieren<\/button><\/div><textarea id=\"result-f-2\" readonly style=\"box-sizing:border-box;width:100%;height:240px;padding:12px;border:1px solid #b8d9d5;border-radius:5px;background:#172a2d;color:#eef8f6;font:12px\/1.55 Consolas,monospace;resize:vertical\">**Acme Relay 3.0 is available today for Business and Enterprise**\n\nAcme Relay 3.0 adds a policy simulator, one-click rollback, and expanded audit exports to help administrators deploy configuration changes with fewer surprises. Business and Enterprise workspaces can use these features starting today.\n\nHere is what changed for administrators:\n\n&#8211; **Policy simulator before deploy.** Run a proposed policy against your current workspace state and review the projected effects on users, groups, and devices before anything is pushed.\n&#8211; **One-click rollback.** If a deployed policy behaves unexpectedly, revert to the previous version from the deployment record. Rollback restores the prior policy state; a brief disruption during the transition is still possible.\n&#8211; **Audit export in CSV and JSON.** Export policy history, deployment events, and simulator runs for spreadsheet review or ingestion into your logging pipeline.\n\nSingle sign-on now supports Okta and Microsoft Entra ID. Administrators using either provider can enable it from the identity settings page without a separate connector.\n\nDuring the beta, participating administrators reduced failed policy pushes from 14% to 3%. That figure comes from 42 beta workspaces over 30 days. It reflects those environments and their change volume, and it is not a guarantee of results in yours.\n\nStarter workspaces will receive a read-only version of the policy simulator next quarter. We will publish the rollout date in the release notes.\n\nIf you manage a Business or Enterprise workspace, a reasonable first step is to pick one existing policy, run it through the simulator against a small test group, and compare the projected outcome with what you expected.\n\n**Open the policy simulator.**<\/textarea><p style=\"margin:8px 0 0;color:#4f696b;font-size:13px\">HTTP 200 \u00b7 26.01s \u00b7 263 input \u00b7 1,881 completion \u00b7 score 8\/10<\/p><\/div><\/div><\/section>\n\n\n\n<section id=\"test-3\" data-test-card style=\"box-sizing:border-box;margin:30px 0;padding:clamp(16px,3vw,24px);border:1px solid #b8d9d5;border-left:6px solid #087f8c;border-radius:8px;background:#f2f8f7\"><div style=\"display:flex;flex-wrap:wrap;justify-content:space-between;gap:10px;align-items:center\"><div><span style=\"color:#087f8c;font-size:12px;font-weight:800;text-transform:uppercase\">API Test 3 \u00b7 Bug and test console<\/span><h3 style=\"margin:4px 0 0;font-size:21px\">Coding: TypeScript concurrency<\/h3><\/div><strong style=\"font-size:18px\">9\/10 vs 0\/10<\/strong><\/div><p style=\"line-height:1.65\">Astra returned a strong diagnosis and partial tests; Fable returned no visible answer in this route.<\/p><details><summary style=\"cursor:pointer;font-weight:800\">View exact task<\/summary><div style=\"margin-top:10px\"><button type=\"button\" data-copy-target=\"prompt-3\" style=\"border:0;border-radius:5px;padding:7px 10px;background:#087f8c;color:#fff;font-weight:800;cursor:pointer\">Copy task<\/button><textarea id=\"prompt-3\" readonly style=\"box-sizing:border-box;width:100%;height:190px;margin-top:8px;padding:12px;border:1px solid #b8d9d5;border-radius:5px;background:#fff;color:#172a2d;font:12px\/1.55 Consolas,monospace;resize:vertical\">Diagnose and fix this TypeScript function.
