Explainer https://github.com/WICG/manifest-incubations/blob/gh-pages/predictable-app-updating.md Specification https://www.w3.org/TR/appmanifest/#updating Summary Specify an update eligibility algorithm in the manifest spec. This makes the update process more deterministic and predictable, giving the dev more control over whether (and when) updates should apply to existing installations, and allowing removal of the 'update check throttle' that user agents currently need to implement to avoid wasting network resources. Blink component Blink>AppManifest Web Feature ID manifest Motivation - Consistency: Provide a consistent way to detect when a manifest update should happen. - Preventing unnecessary user interruption: Users should not see an update dialog more than necessary to confirm security-sensitive changes. - User agent flexibility: It should be possible for users agents to use their judgement to block updates for known bad sites, allow known trusted apps to update without UX, or allow tiny visual changes to icons without requiring UX. - Developer control: Developers should have more control over when the update dialog may show to users. - Reduce network traffic: Unnecessary network traffic should be minimized.

Web developers: Positive (https://www.w3.org/2022/09/13-webapps-minutes.html#t02) Discussions at TPAC 2022 and 2023 involved active discussion with developers, with a positive consensus.

N/A, feature isn't launching on Android. Debuggability No information provided Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?

True Tracking bug https://issues.chromium.org/issues/403253129 Launch bug https://launch.corp.google.com/launch/4393456 Availability expectation Feature is available only in Chrome. Adoption expectation This feature paves the way for PWA app migration [1], which is an ask by both first party and third party vendors as an essential feature for PWAs (crbug.com/380486617). [1] https://github.com/WICG/manifest-incubations/blob/gh-pages/pwa-migration-explainer.md Non-OSS dependencies Does the feature depend on any code or APIs outside the Chromium open source repository and its open-source dependencies to function? N/A Estimated milestones Shipping on desktop 143 DevTrial on desktop 143 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (eg links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (eg, changing to naming or structure of the API in a non-backward-compatible way). N/A, anticipated spec changes will not be introducing interop risks. Changes are being made on Chrome's end to make PWAs more safer.
