Over the past few months, we've been working incredibly hard on @tanstack.com Form v2. We're working hard on getting an alpha your way (maybe even within the week 👀) but can already share some of the updates we recorded earlier this week. Check it out: www.youtube.com/live/eMBGraf...

TanStack is Doing What?

Claude Mythos is GA!... Kinda. www.anthropic.com/news/claude-... They just announced Fable 5, a "Mythos class" model. It scores 80.3% on SWE bench vs Opus' 69.2%... The catch is that it's 2x the cost of Opus 5.8.

Claude Fable 5 and Claude Mythos 5

Today we’re launching Claude Fable 5: a Mythos-class model that we’ve made safe for general use.

This week I joined Stord as the Senior Engineering Manager of their AI team! I wrote a "Working with Me" for my team & thought it'd be fun to share with the rest of you as well: playfulprogramming.com/posts/workin... I'm excited to join the team and scale us to the next level! To the future! 🥂

@dashlane.com, I was one of the customers who received a "someone attempted a login" email. Frankly, I find the lack of official comms deeply upsetting and will likely be the reason I change password managers after the incident resolves. No site banner, no socials. Unacceptable.

In @npmx.dev you can now view a package's changelogs currently only package's that use Github to host their releases or changelog.md are supported but support for others are planned

Finally! A way to pass Chrome debugging to any tooling, not just Antigravity. Can't wait to see its integration with tools like OpenCode: developer.chrome.com/docs/devtool...

I know/understand the ecosystem's qualms with Chrome's prompt API Today they introduced the WebMCP experiment which, on first glance, makes me think that this could serve as a more model agnostic prompt API support; offloading LLM to browser itself Seems neat developer.chrome.com/docs/ai/webmcp

Ooooh what, contrast-color() is newly available across browsers?!: https://webstatus.dev/features/contrast-color

In many of my comms about the TanStack attack, I mentioned a list we published to keep us accountable. But I only realized that this was removed between the draft I saw and the public publication. We'll have this all in a blog post very soon, but 🧵 on what we're fixing

Earlier May 11th, many TanStack Router/Start packages were compromised, but quickly mitigated. Here is a full post mortem on the incident: tanstack.com/blog/npm-sup...

We at TanStack just had a major attack against our Router packages. We have a postmortem out now explaining what happened and how we mitigated the response: tanstack.com/blog/npm-sup... No other TanStack packages outside of the Router monorepo were impacted

I wrote about everything I've felt, feared, and experienced about using AI for code over the last few years, and my opinions on where we stand. It's the most personal thing I've ever written. And I'm putting it out there to share with all of you. blog.isquaredsoftware.com/2026/05/ai-t...

I wanted to give you all a sneak peak of TanStack Form v2. Luca, one of our maintainers, has been working hard on a complete rewrite of the package using new architecture patterns. Minimal breaking changes in userland, insane performance gains. Here's v2 rendering 10,000 fields with validation.

TanStack Form has hit 2M weekly installs!

Vue support in TanStack Form is going to get much better when Vue 3.6 drops. We just had a major blocker fixed through a merge upstream by @fuzzyma.bsky.social Excited for this one!

Your web prayers, answered. Coming soon. Amen.

Also, THIS happened!! 🤯

The most upvoted feature of TanStack Form is formally in development: github.com/TanStack/for... Yes, Form Groups are well on their way! I'm hoping to move quick on this one, but transparently our TODO list is a mile long to get this stable. Stay tuned!

Welp, that's a first... While setting up CI for a Bazel project, I found a bug with one of the packages I'm using when combined with PNPM 11. github.com/aspect-build... Was tricky to nail down... But at least the issue isn't because of my misconfiguration for once haha

What is the current behavior? Right now, when using PNPM 10, everything works well. However, when PNPM 11 is released (currently RC.0), it will break usage with this library. This is because lockfi...

@vicflix.dev 👋 Hey! I have some thoughts/questions about this page: reglejs.dev/introduction... But also wanted to say "hi" since I've only just ran into your library and adore meeting others in the Form space. Game to DM and/or find some time for a coffee chat? 😄

I once asked for a double-promotion in title alone, not fully understanding the consequences of doing so. Here's my story of how, once I got my wish, my recruiter inbound messages died entirely:
