  • New CssLayout layout component
    [list]
  • A fast low-level layout where the contained components are rendered as trivially as possible under a single div element.
  • Result can be similar to VerticalLayout or HorizontalLayout, depending on CSS, but is noticeably faster.
  • No spacing, alignment or expansion rations, unlike with the more feature rich layouts.
  • No abstraction of browser differences; you need to make sure the CSS supports all the browser that you want your application to support.

    [/list]
  • Full support for Internet Explorer 8

Just tried 6.1 in one of our applications - IE6 performance gain is very noticeable, comparing with 6.0.1.
Did not try new lite layouts yet but at least table caching optimization work great ! :slight_smile:

Apart some incompatibilities or changed styles in reindeer theme (our custom, reindeer based theme begun displaying original reindeer parts on buttons), everything works as usual and nothing seems to be broken.

Great job, guys , thanks !

Hy,

I did some tests but I can not upload files with Google App Engine, you have any suggestions?

I noticed that not even enter into Receiver and Google logs do not see anything!

Hello, Davide

Please write a
bug report
with a test case so that we can reproduce this issue. Uploading should work correctly in GAE, but as noted in release notes, application is locked during upload and can not send progress bar updates.
