Ultralight v1.2.0 is now ready for beta testing!

Please see our porting guide if you're migrating from v1.1.

This major update integrates latest changes from WebKit, improves upon a range of rendering issues, adds a new pure-CPU renderer for easier usage in games and limited-GPU environments, and offers improved performance and decreased runtime memory usage.

Note: no size optimizations have been performed on binaries yet, expect additional improvements for the final stable release
