Features

• Add Env.PREVIEW, the VITE_MINIFY and REFLEX_NO_AUTOPREFIXER environment variables, a minify/cssMinify option on the vite config template, and a REFLEX_NO_AUTOPREFIXER toggle in the generated postcss.config.js to support the new preview run mode. (#6663)
• Add a staged Plugin.register_route hook with add_page and has_app_page capabilities that runs once per app before its first compilation, and rx.plugins.get_plugin() to look up the configured plugin instance by type (raising ConfigError on ambiguous matches). (#6728)

Bug Fixes

• Preserve runtime value types for unannotated @rx.memo component parameters. (#6659)
• Compare timezone-aware datetime Vars by their instants instead of their serialized UTC offsets. (#6767)
• In python 3.13+, the EventProcessor loop was not catching asyncio.QueueShutdown resulting in uncaught exceptions during shutdown. (#6773)
• Prevented edits to unloaded routes from poisoning React Router's browser-side HMR queue and blocking all later hot updates until a full page reload. (#6774)
• Drain queued same-token events during graceful event processor shutdown. (#6791)
• Custom attributes on a Field are now carried onto the rebuilt field by reference instead of deep copy, so stateful callable markers keep their identity and markers holding non-copyable values (locks, clients) no longer crash state class creation. (#6809)

Miscellaneous

• Bumped bundled frontend dependency pins to their current releases:

  • react / react-dom: 19.2.6 → 19.2.8
  • react-router, react-router-dom, @react-router/node, @react-router/dev, @react-router/fs-routes: 7.15.0 → 7.18.2
  • isbot: 5.1.40 → 5.2.1
  • universal-cookie: 7.2.2 → 8.1.2
  • postcss: 8.5.14 → 8.5.23
  • autoprefixer: 10.5.0 → 10.5.4
  • vite: 8.0.16 → 8.2.0
  • @tailwindcss/typography: 0.5.19 → 0.5.20
  • Bun: 1.3.13 → 1.3.14

  Also raised the rich upper bound to <16 (adopting rich 15). Replaced the now-redundant cookie package.json override (universal-cookie 8 and react-router resolve cookie to 1.x on their own) with a postcss override pinning it to 8.5.23 (also satisfying vite 8.2.0's ^8.5.23) so transitive resolutions stay on a patched release (>= 8.5.18) for a security advisory.

  (#6678)

• Remove the unused REFLEX_USE_TURBOPACK environment variable. Turbopack is a Next.js bundler; the flag has had no effect since Reflex moved to React Router and Vite in 0.8. (#6803)
