[webkit-help] Which version of Webkit inside iBooks 1.2.1

[Toshiya TSURU]

Hello.

This is my first post on this mailing list.
My name is Toshiya TSURU at Tokyo, Japan.

I'm trying whether html5 features work or not in EPUB format on iBooks.
Some of the features are work, such as <svg>, but <canvas> NOT work.

I remember that iBooks uses Webkit.
I'm wondering Which version of Webkit inside iBooks 1.2.1.

Does anyone know?
