Install the Felix CLI.
Install Felix 3, the breaking-change successor to Felix 2.2.0. Felix 3 uses a separate project configuration; review the migration guide before upgrading.
Felix 3 is a preview release. V2.2.0 is the final Felix 2 release. Existing Felix 2 projects are not converted automatically. Run
felix v3 migrate to preview setup, or felix v3 migrate --harness <provider> --apply to create a separate V3 config while preserving V2 data. Felix Cloud users must upgrade to Felix 3 when the Cloud V3 cutover is announced.Recommended
