The Dev channel has been updated to 5.0.396.0 for Windows, Mac, and Linux platforms

All
  • The toolbar, omnibox and other UI changes reverted for Chrome 5 have been restored in this build.
  • Fixed bug related to scheme stripping that could cause URLs of the form "http://ftp.foo.com" to be misnavigated, by not stripping the scheme in this case.
  • Many bugs fixed relating to stripping "http://" and its interaction with the clipboard. Chrome should now prepend schemes onto the pasted text in a variety of situations.
Mac
  • Continual polish to main frame UI, including the bookmark bar
Linux
  • Bookmark bar icons should no longer be cropped under some GTK themes
    (particularly, the new ones in Ubuntu Lucid).
  • Flash content when using nspluginwrapper should be clickable again.
Security
  • Linux: Fixed a crash caused by a premature application data record in the middle of an SSL handshake (Issue: 42538)
Known Issues More details about additional changes are available in the svn log of all revision.
