Unified Editor
Unity is now the best editor for multi-platform projects. The new Build Settings window lets you set your primary Editor Mode or build to any of your target platforms. New Platform Defines let you include or exclude code for a specific platform at compile-time, so you can work with one project and one set of scripts.
Numerous Editor workflow improvements and enhancements have been added, including:
Redesigned Player Settings -- for customizing your game experience on multiple platforms
All-new Object Picker -- for quickly viewing and selecting object assignments
Smarter Texture Importer -- for optimizing your textures based on how they'll be used
Vertex Snapping -- for quickly designing levels and environments
Curve Editor -- for defining curves right inside the Inspector
Searching -- in scenes and your whole project

Lightmapping
Beast by Illuminate Labs is fully integrated in Unity. Set up your lights in Unity and bake them into high-quality Lightmaps to give your game that extremely polished look.
光照贴图改进
Deferred Rendering (Pro only)
Render more real-time lights, faster. 'Nuff said.
延时渲染
Occlusion Culling (Pro only)
Occlusion Culling will disable rendering of objects that are not visible from the camera's view. In Unity you can precisely define occlusion settings and visualize baked occlusion data.
Occlusion Culling算法
Debugger (Pro only)
Inspect all the dynamics of your code at runtime. Step through your code line-by-line and watch the state of properties. Fix script problems faster!

Audio Features
Design your environments with AudioReverbZone and Rolloff Curves. Apply real-time Audio Effect Filters (Pro only) to any playing sound. Precisely control playback with Audio API additions.
声音功能改进
Physics
Tons of Physics additions have been added, including:
Interactive Cloth -- which simulates cloth behavior on any mesh
Skinned Cloth -- which brings cloth simulation to rigged characters
Continuous Collision Detection -- for handling collisions of fast moving objects
Layer-Based Collision Matrix -- define which layers of objects can collide with which others
SphereCasts and CapsuleCasts
物理学功能的增加或改进
Tree Creator
The Tree Creator allows you to create and edit trees procedurally using a powerful interface. These can be used in terrains or as regular GameObjects. Wind Zones give trees added behavioral realism.
树木创作
IME Text Input
IME Input allows non-English characters such as Japanese or Traditional Chinese to be used as input in your games or the Editor.
字符支持
Native Font rendering
Dynamic fonts are optimized for size, and rendered by the OS running the Unity Engine. This enables IME Input for huge character palettes like Japanese Kanji without needlessly increasing the size of game assets.
原生字体支持，其中包括中文字体
Mono Update
Several scripting improvements and additions have been made.
mono更新
Networking Update
RakNet was upgraded to version 3.732, and improvements have been made to the Master Server and NAT Punchthrough.
网络功能更新
Security Sandbox
In Unity 3.0, the webplayer implements a new security model. This will affect you as a content developer if you use the WWW class to access data on a domain other than the one hosting your .unity3d file, or if your content uses sockets.
