Been reading the docs and I have a LOT to say but

I've been using this lovely, friendly guide to figure out how to write WASM assembly

https://developer.mozilla.org/en-US/docs/WebAssembly/Guides/Understanding_the_text_format

(The spec https://webassembly.github.io/spec/core/_download/WebAssembly.pdf is a little hard to work with)

And saw this really alarming note implying the guide hadn't been updated since 2020 (is that when Mozilla fired everyone?)

Can anyone recommend how I'd find out what has changed in Wasm between 2020 and 2025? Assume I'm targeting wasmtime and can be cutting edge.
