 # Changelog
 
+## 3.0.0-next.49
+
+### Patch Changes
+
+- be766d6: `dev: false` now serves Solid's production builds under `vite dev`, as documented (#62). The plugin already dropped its own `development` condition, but Vite's default `development|production` condition resolves to `development` in any non-production mode, so the client still pre-bundled `solid.dev.js` / `web.dev.js` and SSR loaded `server.dev.js`. With `dev: false` the plugin now rewrites that condition to `production` under `vite dev`; vitest runs and `vite build` keep Vite's default resolution. Vite conditions apply per environment, so other packages that ship a `development` export also get their production builds in that case. It also stops emitting HMR refresh wrappers and pre-bundling `solid-js/refresh`, because the production refresh runtime is an inert stub that only warns; edits fall back to a full reload. The diagnostics bridge also stays off with `dev: false` unless `observe` is on, since its channels exist only in the dev and observe builds.
+- af79dd8: Plain `.ts` and `.js` modules now get lazy callsite module URLs and, on the server, a `$$moduleUrl` export. Non-JSX files used to return before that pipeline, so a `routes.ts` of `lazy(() => import(...))` never told SSR which module to preload.
