An issue has come up during each jump between major Vite versions where the plugin will fail builds or CI pipelines when users of the plugin bump a major version of Vite beyond what was explicitly supported. Since the API this plugin rests upon seems quite stable and has not experienced any breakages over the past 4 major version changes, I assume that the foreseeable future of major Vite releases will not break the plugin. Therefore, all future versions of Vite have been optimistically included as a valid peerDependency.
This change should remove this plugin as a blocker from your upgrade path especially in the case of trying out future beta releases of Vite.
