Chromium based Opera 17.0 FINAL is now available for download. This version includes small but worthwhile new features like "pinned tab" and custom search options which is already available in Google Chrome and Firefox.
Looks like Opera has lost the browser war!
Pinned Tabs -There’s more control over Opera’s starting page. By default the browser just resumes where you left off, but a new Start-Up option (Settings > Preferences > General) now allows you to start with your home page, Speed Dial or the startup dialog.
Custom Search Engines - besides pre-installed search providers that Opera ships, now you can add your own searches. For example, to configure "d" to search DuckDuckGo, choose O>Manage Search Engines, and under "Other Search Engines" add "DDG" in the first input field, "d" in the second to define the shortcut and "https://duckduckgo.com/?q=%s" in the third.
