I need permalinks to a given version of the spec, which I can reference in implementation source code and requirements of our interpreter.
Luckily, W3C got us covered:
https://www.w3.org/standards/history/wasm-core-2/ has the history of all releases of the Wasm 2.0 core specification.
It provides a permalink to the currently most up to date version of the CRD:
https://www.w3.org/TR/2025/CRD-wasm-core-2-20250616/
Within that document, however, some links are broken. I.e. here: when clicking the memory intance link beneath mem_read, it redirects us to
https://www.w3.org/TR/2025/CRD-wasm-core-2-20250616/index.html#syntax-meminst
which does not exist (i.e. we get a "Document not found" landing page). The culprit in that link is the index.html. Removing that makes the link work.
Notably, not all links are broken, i.e. the memory instance link in beneath here is fine.
Thanks to my colleague @cemonem for pointing out this bug.
