Here's a few:
- Baked in Content-Security-Policy support.
- Improved support for lazy-loading and comet-AJAX interactions.
- Built-in support for streaming a lazy Stream of data to the client.
- Built-in support for client-bound functions that call into the server.
- Improved JSON serialization performance (up to 90% faster).
- Deep support for Future and LAFuture, both in REST responses
and on the right-hand-side of CSS selector binds.
- Ability to trigger Lift snippets via custom `data-*` attributes.
Thanks,
Antonio
