After three betas we’re proud to release the shiny new Opera Mini 4 to the world. We’ve done a lot with this new Opera Mini. For example, we rewrote the entire code for Opera Mini 4 and added lots of improvements and new features to make the browser even better.
Opera Mini 4 is based on the same rendering engine as the Opera 9.5 desktop browser. The browser still has a very small install size, less than 100k, even though we’ve added all these cool new features. With all the time and work that we’ve put in on our end, we wouldn’t be able to bring you the world’s best mobile browser without your help and support. We owe a great amount of appreciation to all those of you who helped with our beta testing, bug reporting, and providing feedback in the Opera Mini forums and on your blogs. Thanks.
