Sorry, I have to call shinanegans on this.
How long has it been since Opera switched to using Presto? It's been over 12 months, and Linux users haven't had an updated browser since then either. 15 months it's been since the release of 12.16.
In those 15 months, your comments regarding stability sgunhouse is the FIRST thing I've seen any news about the delay Opera are having with a release for Linux. While I was on Facebook I would often ask the page owner/employee about the status of a new browser for Linux and I was always met with "Oh we're working on it". I keep coming back to the page nearly every month to see if a new version of Opera is available and I see 12.16 still there.
What, exactly, is going on? I think the Linux community deserves a better answer than the ones we're being given. I understand software can have bugs etc, but is this more of a resource issue with Opera than blaming the operating system for needing continual updates (which, quite frankly, isn't true). After 15 months of nothing I think the community deserves an explanation.
