Today’s update to developer starts the process of stabilization—to bring it up to beta quality. As you would therefore expect, all changelog entries are bugfixes rather than major feature improvements. In addition we have upgraded Chromium to 42.0.2311.11.
Please let us know how close we are too beta quality, so that we can get the first 29 beta out the door and get the developer stream onto the Opera 30 bandwagon.
P.S. The sidebar feature will be disabled for the upcoming 29 beta, since it still requires a fair amount of work before it is at sufficient quality level. However, it is still enabled on the developer stream and we will do further work for on it for Opera 30.
