来自Apple的信，简单翻译一下。

Dear Aperture customer,
Last June, we introduced the new Photos apps for iOS 8
and OS X Yosemite, along with iCloud Photo Library, which
lets you safely store all your photos in iCloud and
access them from anywhere.
When Photos for OS X launches this spring, Aperture will
no longer be available for purchase from the Mac App Store.
You can continue to use Aperture on OS X Yosemite, but you
will not be able to buy additional copies of the app.
You can migrate your Aperture library to Photos for OS X,
including your photos, adjustments, albums, and keywords.
After migrating, your Aperture library remains intact.
However, Aperture and Photos do not share a unified
library, so any changes made after the migration will not
be shared between the apps.

If you’re interested in trying the OS X 10.10.3 Public Beta, which
includes Photos for OS X, click here. http://tinyurl.com/n2exk8j
We thank you forusing Aperture and hope you will enjoy the new Photos for
OS X app.
Sincerely,
Apple

亲爱的Aperture使用者：
去年六月，我们在OSX Yosemite上及iOS8上介绍了新的Photos App，也同
时发布了新的iCloud Photo，能让你无时无刻都可以储存你的照片于iCloud
上并使用它们。
在Photos App于今年春季发表之后，Aperture将不在提供购买，您可以
继续使用Apteture，但您将无法在Mac App Store购买任何Aperture。
您可以移动你的Aperture数据库至Photos App中，包含您的照片，修改后的
版本资料、相簿、关键字。在移动之后，您的Aperture数据库依然可以使用。
但是，Aperture和Photos App并不是分享同一个数据库的。也就是说，在移动
后的任何修改，将不会在这两个软件之间分享。
你可以借由这个连结 http://tinyurl.com/kafovf3 了解更多Photos App，
你也可以参与OSX10.10.3的公开测试 http://tinyurl.com/n2exk8j 。
感谢您使用Aperture，希望您能继续享受我们新开发的OSX Photos App。
感谢
Apple

心得及重点：
“Aperture和Photos App并不是分享同一个数据库的。也就是说，在移动
后的任何修改，将不会在这两个软件之间分享。”
这太让人犹豫了，Photos看起来漂亮、顺畅，但是更专业的调整（GPS、颜色、
脸部辨识…）都是我觉得非常重要的。有点割舍不了Aperture....
大家会转换到Photos App吗？
