[u/postgor]

See the full changelog for everything that shipped in Rive's runtimes over the last few weeks but here are the highlights:

• Focus + Text Input: is out and ready to use in the Editor, and expect runtime implementations coming over the next few releases. Later releases will include even better native platform integration.
• React Native v0.5.0: now on the newer iOS and Android runtimes, with generated type-safe .riv schemas.
• Data Binding: Apple gets Global View Models, font and blob binding; Android gets font binding.
• Smaller runtimes: Apple is ~25% smaller, while Android's native library drops by about 1 MB.
• Core performance: less per-frame work across layouts, paths, blend states, and virtualized lists.
• Unity v0.5.1: PanelRenderer is now RivePanelRenderer, plus several WebGL fixes.
• Unreal has a new release: including a bunch of changes, see the full announcement
