Hi, this is Patrick Dubroy and Mariano Guerra. You're getting this email because you purchased (or signed up for updates about) WebAssembly from the Ground Up. If you're no longer interested in these emails, no hard feelings — you can find an unsubscribe link at the bottom.
Greetings, WebAssembly-ians!
We have two quick updates for you. First off, yesterday we published the first post-launch update to the book. It included a host of minor changes:
- We added a few tips for debugging generated Wasm to About the Code.
- The appendix now contains all remaining instructions from the 1.0 spec.
- In What makes WebAssembly safe?, we added a paragraph about memory safe. (Thanks for the suggestion, Job!!)
- In the PDF, we fixed a few code blocks which didn't show the full contents.
…and more. As always, you can find a comprehensive list in the changelog, which is linked from the table of contents.
Workshops
In other news, we're starting to prepare material for a workshop based on the contents of the book. If you're at all interested in attending a WebAssembly from the Ground Up workshop, we'd love it if you could fill out a quick survey:
It will only take you a minute or two to fill out, and it would help us a lot to know what kind of workshops people are interested in. Thanks!
Wasm tidbits
- Threading the needle with concurrency and parallelism in the Component Model — Luke Wagner's presentation from Wasm I/O 2025

That's all for now!
