Future warnings when enabling future: 'warn' in Vite 7.2 with @vitejs/plugin-vue2

[thefutureislimitless]

Describe the issue

After upgrading our project to Vite ^7.2.2 we enabled the new future: 'warn' option in defineConfig to track upcoming breaking changes. Starting the dev server shows multiple warnings coming from @vitejs/plugin-vue2:

• server.warmupRequest is replaced with this.environment.warmupRequest.
• Plugin hook options.ssr is replaced with this.environment.config.consumer === 'server'.
• Plugin hook handleHotUpdate() is replaced with hotUpdate().

Each warning links to the Vite documentation detailing the new Environment API changes.

Reproduction

1. Create a Vue 2.7 project (e.g. via create-vue + downgrade to Vue 2).
2. Install Vite ^7.2.2 and @vitejs/plugin-vue2@2.3.4.
3. In vite.config.js add future: 'warn'.
4. Run pnpm run dev (or vite dev).
5. Observe the future warnings in the terminal.

Our actual project is a Vue 2.7 + Ant Design Vue admin dashboard, but the reproduction above should be enough.

Expected behavior

@vitejs/plugin-vue2 should migrate to the new Environment-aware hooks (hotUpdate, this.environment.*, etc.) so that enabling future: 'warn' emits no warnings.

Additional context

• Vite: ^7.2.2
• @vitejs/plugin-vue2: 2.3.4
• Node: 24.11.0
• Package manager: pnpm 10.20.0
