If you are a V2 user, you will find a lot of new features in V3. There are, however, two types of improvements: new platform (more invisible) and new features (more visible).
The New Platform
Each time we released a new version, we made some aggressive optimization in the platform and architecture. This time there's also some big improvements.
* The keyboard is now designed to support a variety of layouts. In addition to the two-key layout, we added the single-key layout and 9-key layout.
* The "Flow" engine can detect your gesture and move up the keyboard.
* SDK tools for building language packs are now available. We will open it to limitted partners who could help us develop more language packs.
* Images are seperated from the DLL and thus make the DLL file much smaller. This would help resolve the loading issue on some resource limitted models.
The New Features
* "Flow" your keyboard - You can switch layouts or turn pages by sliding left or right on the keyboard.
* Skins are supported - You can download different skins or design your own skins.
* Press & hold - For those who don't like sliding, now you can hold a key to expand all the possible characters.
* Change priority of a word in dictionary, or delete a custom word.
* Key press sound effect.
* Prediction based on context - The prediction engine can now guess the word based on what you have typed. For example, if you typed "let" and then type for "us", the word "us" will appear prior to "is".
* Next word prediction - If you typed "look", the word "forward to" will be shown in the candidate list.
Of course, this release fixed a bunch of bugs including the uninstall issue in the previous version.
