   This device-level policy configures whether <ph name="PRODUCT_OS_NAME">$2<ex>Google ChromeOS</ex></ph> will offer a post-quantum key agreement algorithm in TLS, using the ML-KEM NIST standard. Prior to <ph name="PRODUCT_OS_NAME">$2<ex>Google ChromeOS</ex></ph> 131, the algorithm was Kyber, an earlier draft iteration of the standard. This allows supporting servers to protect user traffic from being later decrypted by quantum computers.

   Offering Kyber is backwards-compatible. Existing TLS servers and networking middleware are expected to ignore the new option and continue selecting previous options.
 
   However, devices that do not correctly implement TLS may malfunction when offered the new option. For example, they may disconnect in response to unrecognized options or the resulting larger messages. Such devices are not post-quantum-ready and will interfere with an enterprise's post-quantum transition. If encountered, administrators should contact the vendor for a fix.
 
-  This policy is a temporary measure and will be removed sometime after <ph name="PRODUCT_OS_NAME">$2<ex>Google ChromeOS</ex></ph> version 141. It may be Enabled to allow you to test for issues, and may be Disabled while issues are being resolved.

   Offering a post-quantum key agreement is backwards-compatible. Existing TLS servers and networking middleware are expected to ignore the new option and continue selecting previous options.
 
   However, devices that do not correctly implement TLS may malfunction when offered the new option. For example, they may disconnect in response to unrecognized options or the resulting larger messages. Such devices are not post-quantum-ready and will interfere with an enterprise's post-quantum transition. If encountered, administrators should contact the vendor for a fix.

+  The ServiceWorkerAutoPreload feature dispatches a network request for a main resource at the same time it begins the ServiceWorker bootstrap process.
+
+  Setting the policy to Enabled or leaving it unset means
+  <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph> enables ServiceWorkerAutoPreload. The navigation request is automatically dispatched while starting the ServiceWorker in some scenarios, e.g. ServiceWorker is not running,
+
+  If it is disabled, <ph name="PRODUCT_NAME">$1<ex>Google Chrome</ex></ph> will not enable ServiceWorkerAutoPreload. The navigation request is dispatched always after starting the ServiceWorker.
+
+  This policy is a temporary measure to control the feature and will be removed in M144.

   If the policy is not set, <ph name="IP_PROTECTION_NAME">IP Protection</ph> will be enabled by default and users will be able to control the feature on their device via UI settings.
 
   Some considerations regarding whether enterprises should disable <ph name="IP_PROTECTION_NAME">IP Protection</ph> include:
+
   - DNS lookups won't be performed for requests that are proxied, which may impact DNS-based monitoring or filtering.
+
   - Enterprise applications may experience breakage when used in Incognito mode if they rely on requests to domains (or subdomains of those domains) on the Masked Domain List (<ph name="MASKED_DOMAIN_LIST_URL">$1<ex>https://github.com/GoogleChrome/ip-protection/blob/main/Masked-Domain-List.md</ex></ph>) and require those requests to come from specific IP address ranges.
+
   - Traffic might not be proxied in Incognito mode under certain conditions, for example when users launch Incognito mode from a Chrome profile they aren't signed in to. In general the feature requires the user to have been signed in to Chrome with a personal Google account when launching Incognito mode.
+
   - The list of domains on the Masked Domain List may change over time, with new versions being pushed to users automatically. For more information on the Masked Domain List, see: <ph name="MASKED_DOMAIN_LIST_CRITERIA_URL">$1<ex>https://github.com/GoogleChrome/ip-protection/blob/main/README.md#identifying-domains-and-the-masked-domain-list-mdl</ex></ph>.

+caption: Enable post-quantum key agreement for WebRTC
+default: null
+desc: |-
+  This policy allows controlling post-quantum key agreement for WebRTC.
+
+  If this policy is set to Enabled, post-quantum key agreement would be offered for
+  WebRTC.
+
+  If this policy is set to Disabled, post-quantum key agreement would not be offered
+  for WebRTC.
+
+  If this policy is not set, the value would be set by the default rollout process
+  for post-quantum key agreement offered for WebRTC.
+
+  Offering a post-quantum key agreement is backwards-compatible. Existing DTLS
+  peers and networking middleware are expected to ignore the new option and
+  continue selecting previous options.
+
+  However, devices that do not correctly implement DTLS may malfunction when
+  offered the new option. For example, they may disconnect in response to
+  unrecognized options or the resulting larger messages. Such devices are not
+  post-quantum-ready and will interfere with an enterprise's post-quantum
+  transition. If encountered, administrators should contact the vendor for a fix.
+
+  This policy is a temporary measure and will be removed after some milestones.
