We have some sad news for the 0.1% of our users who are still on the PowerPC architecture.
Starting with the Next version of Opera, as of the next snapshot release (due sometime later today), we are discontinuing the PowerPC architecture on Mac and Linux. Opera 10.6x will be the last release with support for this architecture. This is unfortunate, but with third party vendor support dwindling away, we can no longer keep developing Opera for this architecture.
After ending support for PowerPC, we will be able to focus more on our high quality browser to make sure that it meets the need of the modern web browser user on the popular architectures.
