29 September 2022 The  Distributed Tracing Working Group  has published a First Public Working Draft of  Trace Context Level 2 . This specification defines standard HTTP headers and a value format to propagate context information that enables distributed tracing scenarios. The specification standardizes how context information is sent and modified between services. Context information uniquely identifies individual requests in a distributed system and also defines a means to add and propagate provider-specific context information.

  The  Web Application Security Working Group  has published a First Public Working Draft of  A Well-Known URL for Changing Passwords . This specification defines a well-known URL that sites can use to make their change password forms discoverable by tools. This simple affordance provides a way for software to help the user find the way to change their password.

  The   Math Working Group   has published a First Public Working Draft of   Mathematical Markup Language (MathML) Version 4.0 . MathML is a markup language for describing mathematical notation and capturing both its structure and content. The goal is to enable mathematics to be served, received, and processed on the World Wide Web, just as HTML has enabled this for text. This specification is intended primarily for those who will be developing or implementing renderers or editors, or software that will communicate using MathML. About 38 of the MathML tags describe abstract notational structures, while another about 170 provide a way of unambiguously specifying the intended meaning of an expression. While MathML is human-readable, authors typically will use equation editors, conversion programs, and other specialized software tools to generate MathML. MathML4 is the 4th version of the language, which started with MathML 1 in 1998.

  The   Web Payments Working Group   have published Recommendations of   Payment Request API   and   Payment Method Identifiers . Payment Request standardizes an API to allow merchants (i.e., web sites selling physical or digital goods) to utilize one or more payment methods with minimal integration. Browsers facilitate the payment flow between merchant and user. Payment Method Identifiers defines payment method identifiers and how they are validated, and, where applicable, minted and formally registered with the W3C. Please see the  disposition of comments  following review by the W3C Membership.

  The  Accessible Platform Architectures (APA) Working Group  has published a first Draft Note of the  W3C Accessibility Maturity Model . The W3C Accessibility Maturity Model best practices document enables organizations to implement processes and systems in key areas that can objectively measure whether the correct steps have been taken to keep the entire product experience accessible. Comments are welcome through  16 October 2022 .
