Dear GWT lovers,
It has been decided not to turn GSS on by default in GWT 2.8 in order make the migration to the new GWT release simpler and smoother for everyone and let people migrate at their own timeline.
You will still have to use the configuration property CssResource.enableGss to enable GSS.
A new configuration property has been added: CssResource.gssDefaultInUiBinder. This config property allows you to enable GSS by default in uibinder (ne need anymore to add the attribute gss=true in your inline style)
Don't hesitate to comment the document or give you opinion by replying to this mail.
