@w3c is rolling out Activity pages for its groups, offering a month-by-month overview of their work in one place. They bring together their charters, publications, meetings, participants, and GitHub activity.

▶️ https://www.w3.org/blog/2026/introducing-group-activity-pages/

The pages are in beta, and we welcome your feedback! https://github.com/w3c/w3c-website/issues

The project will also be discussed at #w3cTPAC during a breakout session to explore how this activity data could better serve the W3C community.

The Verifiable Credentials Working Group published a series of W3C Working Group Note Drafts for threat models. All identify and analyze security and privacy threats specific to their recommendation-track documents:
Recognized Entities Threat Model v1.0
Data Integrity Threat Model v1.1
Verifiable Credential Barcodes Threat Model v1.0
Verifiable Credentials Render Method Threat Model v1.0
VCALM Threat Model v1.0

A portrait-oriented mobile device displays the comic "I’m a Villainess to be Poisoned, so why am I being adored?" by Isana Mizuki and Itoshiki. The user scrolls through the comic, with panels moving seamlessly.

There's a really cool alignment feature in CSS Grid Lanes that makes items stretch along the stacking axis, filling any remaining empty space.

It's great when you don't want the usual jagged edge at the end of your layout.

In 2026, the project advanced efforts to integrate #accessibility support data into #developer tools such as the Browser Compatibility Data (BCD) and Baseline, with a proof of concept using Web Platform Tests and ARIA-AT data. Work continues on filling data gaps and defining support statuses, with a TPAC 2026 breakout inviting community input!

✍️ #blog What’s new in the #W3C Website Design System

A significant update to the W3C Website Design System, built by @studio24 was published at the end of September 2026.
Read the post by @nickithenoodle about what changed and why.

Today is the last day you can submit your 5 minute talk on how AI impacts society, as part of our special W3C mini-workshop during TPAC in Dublin.

You can be there in person or join us remote. Non-members can also join (remote only)

Regulations limiting children’s access to online content have been broadly and rapidly deployed recently, which require that users provide assurance of their age. The consequences of these regulations may result in major changes to the web.

Tara Whalen and Amir Sharif are leading a mini-workshop to explore Age Assurance as part of #w3cTPAC in Dublin on 28 October.

The deadline for proposals has been extended to 8 October. See more at:

I take precisely zero credit for this but the W3C Verifiable Credentials WG that I have the privilege to co-chair has just published a bunch of Threat Models. That is, a series of docs that literally answer the question:

What could possibly go wrong?

VCs are all about proof and provenance. They're a target for bad actors so here's what the WG has worked on to defend against attacks https://www.w3.org/news/2026/first-draft-notes-verifiable-credential-threat-models/

Kudos to Manu, Simone, Joe and others. And to @w3c for this process step.

W3C issues press release about developing Verifiable Credential Barcodes

Recently the data theft of approximately 160 million drivers licenses from the US and Canada was reported and unfortunately, identity thieves will use this data to impersonate victims.

Real-time revocation is needed to protect individuals against identity theft. W3C Verifiable Credential Barcodes are the solution to the future of physical document security. Read more at:

Are you interested in the positive and negative impacts of Generative AI on society and its intersection with W3C's Ethical Web Principles and Vision?

@tzviya, @hdv, and @christianliebel are organizing a mini-workshop on AI and Society in Dublin on 28 October as part of TPAC 2026.

Topics proposed include: AI and accessibility, the user and Agentic AI and enabled emissions. The deadline to submit proposals has been extended to 9 October. See more: https://github.com/w3c/strategy/issues/565

RE: https://w3c.social/@w3c/117393555521007349

Today the @w3c has published a new version of the SVG2 Candidate Recommendation.

* CR is at https://www.w3.org/TR/2026/CR-SVG2-20261006/
* Editor's draft (freshest version) https://w3c.github.io/svgwg/svg2-draft/
* Spec Issues https://github.com/w3c/svgwg/issues/

The SVG Working Group is actively trying to remove the paper cuts and have something which is interoperable. There are many parts of the spec which are not fully tested in WPT. One step at a time, we are improving it.

If you see implementation bugs, issues with the spec, missing tests, do not hesitate to report them. It will help a lot.

Thursday was the 32nd anniversary of the founding of W3C. @dontcallmeDOM noted: "I'm proud that W3C has been a shepherd of the web and encouraged at all the people at W3C who are passionate about a web designed for the good of its users."

32 is a power of two (2^5), so a nice milestone for the geeks among us. To celebrate our 0b100000th anniversary, we've updated our donation pages to power of 2 values — for donations above 2^32, please DM us.
https://www.w3.org/support-us/donate
#GivingTuesday #SupportW3C

#SVG fans rejoice! \o/ 

As of today there is a fresh version of SVG2 with corrections, clarifications and improvements for more interoperability, in particular in implementations in web browsers.

W3C is 32yo.

"To celebrate our 32nd anniversary on October 1, 2026, and for this week only, we updated our suggested donation amounts to power of 2 values, because 32 itself is a power of two!"

“This is for everyone” or “free-for-all”?

The web has shifted from its original open, sharing-focused vision toward concerns over protecting vulnerable populations, copyright and AI data usage, and centralized social media that obscure data sharing and provenance.

Pierre-Antoine Champin and Viivi Lähteenoja will lead a mini-workshop at TPAC2026 in Dublin to explore new forms of data governance, data ownership, and decentralized alternatives.

The Verifiable Credentials Working Group has published a First Public Working Draft of Bitstring Status List v1.1.

This specification describes a privacy-preserving, space-efficient, and high-performance mechanism for publishing status information such as suspension or revocation of Verifiable Credentials through use of bitstrings.
