What do you mean by "Published in mid-2021"? It's still in draft and is undergoing changes. From the Github repo it seems the first (presumably public) commits were in 2019: https://github.com/gpuweb/gpuweb/commit/c325725d5e2b50dcd9e5ec6c0b78d7d2315a7e48 https://github.com/gpuweb/gpuweb/commit/c325725d5e2b50dcd9e5... Edit: I imagine it comes from here: https://www.w3.org/standards/history/webgpu https://www.w3.org/standards/history/webgpu - the first time a working draft was published on the w3c site, instead of only at the github repo, was then. But is it a meaningful date to mention?
