In the issue title above add the document name followed by the date of this request, then the date of your proposed deadline for comments.

• name of specs to be reviewed: WebAssembly Core 2.0, WebAssembly JavaScript Interface 2.0, WebAssembly Web API 2.0

• URL of spec: https://www.w3.org/TR/wasm-core-2/, https://www.w3.org/TR/wasm-js-api-2/, https://www.w3.org/TR/wasm-web-api-2/

• What and when is your next expected transition? CR for 2.0, to transition as soon as reviews are finished (the date provided is not a hard deadline)

• What has changed since any previous review? The specifications contain change history sections summarizing additions to each spec (core, JS, Web)

• Does your document have an in-line Privacy Considerations section, ideally one separate from the Security Considerations? If not, correct that before proceeding further. Yes, although the considerations are spread out across the 3 layers as appropriate, as many considerations which may arise on the web (e.g. same-origin policies) are outside the scope of the core and/or JS specs.

• Please point to the results of your own self-review (see https://w3ctag.github.io/security-questionnaire/ , https://w3c.github.io/fingerprinting-guidance/, https://tools.ietf.org/html/rfc6973): Self-review of security and privacy questionnaire for 2.0 CR transition WebAssembly/spec#1830

• Where and how to file issues arising? https://github.com/WebAssembly/spec/issues

• Pointer to any explainer for the spec? The spec as a whole does not have an explainer but see below.

This is a request for transition for version 2.0 of all 3 WebAssembly specifications, namely the core spec, which defines the core code format and semantics;
the JS API specification, which provides a JavaScript API for interacting with WebAssembly; and the Web API specification, which describes the integration of WebAssembly with the broader web platform.

For review convenience, here is a list of the explainers for the proposals that have gone into 2.0, compared to 1.0 (currently in REC state). These are informal descriptions of the proposed changes and are not canonical, but describe an overview of the feature and could be useful in determining whether there is anything of interest for horizontal reviewers.

Note also that the specifications contain change history sections summarizing additions to each spec (core, JS, Web)
listing and summarizing additions since version 1.0. The table summarizes the effect on the JS spec. The Web spec is unchanged since 1.0
