Google announced About adding to Chrome experimental capabilities “Follow” with the implementation of the built-in RSS client. Users will be able to subscribe to RSS ribbons of their sites through the Follow button on the menu and track the appearance of new publications in the Following section on the opening page of the new tab. Testing a new opportunity will begin in the coming weeks and will be limited to some Chrome users for Android, living in the United States and using the CANARY experimental branch.
Google company also published Cutting the contents of HTTP- User-Agent header. User-Agent support was initially planned to spend a year ago, but due to the COVID-19 pandemic, the introduction of the changes associated with User-Agent was postponed. It is noted that Safari and Firefox has already removed the detail version of the User-Agent version.
In Chrome 89, the default mechanism User-Agent Client Hints , developed as a replacement user Agent, and now Google intends to proceed to experiments on cutting functionality related to User-Agent. User-Agent Client Hints Allows you to organize a selective return on the specific parameters of the browser and system (version, platform, etc.) only after the server request. The user, in turn, can determine which information can be provided by site owners.
When using User-Agent Client Hints, the identifier is not transmitted by default without an explicit query, and by default only the basic parameters are specified, which makes it difficult to conduct passive identification. For sites that you need to get detailed data on the browser in the first request, the “Client Hints Reliability” extensions are developed, which includes the HTTP title server given by the Critical-Ch informing about the fact that to form the content site you want to transfer the “Client Hint” parameters in a separate request, and the extension accept_ch HTTP / 2 and HTTP / 3, at the connection level, transmitting information about the “Client Hint” parameters that the server must be obtained.
