On June 6, 2022, GitHub announced that Atom will officially close down on December 15, 2022.
The Ed-Fi Alliance is aware of this change and plans to change MetaEd-IDE over to run with Visual Studio Code instead of Atom in 2023. In the meantime, we expect that the Atom-based distribution will continue to run without any problems.
Roadmap: VS Code support will be in MetaEd 4.0, with plans to release as soon as possible in the first quarter of 2023.
