New Features

Persistent Frontend Dep Locking

Projects should commit the new reflex.lock directory which includes package.json and bun.lock. This helps avoid accidentally introducing upstream changes and helps protect against supply chain attacks.

With the EmbedPlugin, a Reflex frontend can now be mounted into an existing DOM element in a custom HTML page by simply including the entry point javascript.

feat: support embedding Reflex apps into host pages via mount_target by @FarhanAliRaza in #6462

`frontend_compression_formats`

The build process now produces .gz sidecar files during export and serves them to supported clients for reflex run --env prod.
