So I'm OK shipping before the PR lands. LGTM1 However if the WG converges on a breaking change before this reaches stable, please follow up here. Worst case we can pause the launch before it hits stable and update to reflect any new consensus. But that is looking unlikely so I don't want you to have to wait any longer.

All major issues about privacy and event changeID have been resolved after team discussion. Awaiting final signoffs and possible WG discussion (that's why the Agenda+ label) before merging. There are no blocking problems left as of now. On Thursday, October 23, 2025 at 7:06:53 PM UTC+5:30 Mike Taylor wrote: On 10/23/25 5:31 a.m., 'Rohan Raja' via blink-dev wrote:Thanks for reviewing. The mentioned issue was created in response to the initial explainer of ClipboardChange event API last year. Post this we had good discussions about the ClipboardChange event API in the working group meetings and arrived at an acceptable API signature and permission model for Safari/Firefox.

This allows web-apps like remote desktop clients to keep their clipboards synchronized with the system clipboard. It provides an efficient alternative to polling the clipboard(using Javascript) for changes. *Blink component* Blink>DataTransfer <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EDataTransfer%22> *Web Feature ID* clipboardchange <https://webstatus.dev/features/clipboardchange> *Motivation* Today, a web-app can monitor the system clipboard by polling and reading the clipboard through async clipboard API at regular intervals. For example, web based remote desktop clients like Chrome Remote desktop may read the clipboard contents for changes on every page focus event which is inefficient. Some Github links also suggests polling of clipboard being performed in Electron JS apps like (https://gist.github.com/LewdEwe-ErikWallace/d6e36f899a77a4f05e46388c254d014f <https://gist.github.com/LewdEwe-ErikWallace/d6e36f899a77a4f05e46388c254d014f>).
