The CSS Working Group has published a First Public Working Draft of CSS Logical Properties and Values Level 1. This module introduces logical properties and values that provide the author with the ability to control layout through logical, rather than physical, direction and dimension mappings. The module defines logical properties and values for the features defined in CSS21. These properties are writing-mode relative equivalents of their corresponding physical properties.

The Web Payments Working Group has published a First Public Working Draft of Payment Handler API. The Working Group has previously published Payment Request API, which provides a standard way to initiate payment requests from Web pages and applications. User agents implementing that API prompt the user to select a way to handle the payment request, after which the user agent returns a payment response to the originating site. The new Payment Handler API defines capabilities that enable Web applications to handle payment requests, helping to streamline payments on the Web.
