12.04刚添加了多点触摸手势支持中版本吗？

我正在查看今天要下载的更新，

1. 注意到其中很多与手势支持有关，

2. 注意到其中许多是新安装而不是升级。

12.04是否刚刚添加了支持多点触摸手势的中间版本？如果是这样，这会增加什么功能？哪些应用程序已经支持这些功能，我是否可以期望其他应用程序在不久的将来增加支持？

以下是已安装的软件包：

Install: libframe6:amd64 (2.2.4-0ubuntu0.12.04.1), libgeis1:amd64 (2.2.9.2-0ubuntu1), libgrail5:amd64 (3.0.6-0ubuntu0.12.04.01, automatic)

以下是已升级的产品（还包括许多具有触摸支持的产品）：

Upgrade: libgrip0:amd64 (0.3.4-0ubuntu2~ubuntu12.04.1, 0.3.5-0ubuntu1~12.04.1), eog:amd64 (3.4.2-0ubuntu1, 3.4.2-0ubuntu1.1), ginn:amd64 (0.2.4-0ubuntu1, 0.2.4.1-0ubuntu1)

其中新安装的说明是，

libgeis1：

Gesture engine interface support
 A common API for clients of a systemwide gesture recognition and propagation
 engine.

libframe6：

Touch Frame Library
 This library handles the buildup and synchronization of a set of simultaneous
 touches. The library is input agnostic, with bindings for mtdev, frame and
 XI2.1.

libgrail5：

Gesture Recognition And Instantiation Library
 This library consists of an interface and tools for handling gesture
 recognition and gesture instantiation. Applications can use the grail callbacks
 to receive gesture primitives and raw input events from the underlying kernel
 device.

升级包的说明是，

ligrip0：

provides multitouch gestures to GTK+ apps

 Libgrip hooks gesture recognition into GTK+ applications.

ginn：

Gesture Injector: No-GEIS, No-Toolkits

 A daemon with jinn-like wish-granting capabilities: it gives applications the
 ability to support a subset of multi-touch gestures without having to integrate
 GEIS or multi-touch GTK/Qt libs.

我添加了大量的新库并升级了现有组件，这使我想知道12.04是否打算在不久的将来开始本地支持除两指滚动以外的其他手势。我希望很快会引入这些功能，但是我认为它们只会在新版本中推出，而不是作为现有版本的升级。

有人对此有任何信息吗？

我以为自己有点奇怪。我做了一些挖掘，看起来上游项目已重命名。

• utouch-geis
• utouch框架
• utouch-grail

现在：

• 吉斯
• 帧
• 圣杯

（请参阅错误1029482和1029643）

此更新反映了重命名以及一些错误修复：
