| A desktop release goes out with what can be built. Linux is built on g1t's machines in every release; Windows and macOS each wait on a repository variable: a machine registered for them, or for Windows a cross build on Linux once aka.ms and download.visualstudio.microsoft.com are workflow-only domains, which is where the first release stopped. A platform with no machine is skipped and the download page says it is coming, with a word for the visitor whose platform this release lacks. The guide and CONTRIBUTING say so. | 1 | import assert from "node:assert/strict"; |
