Opera 27 for Linux has been announced today as its first stable release in 2015. The new release brings back the Tab preview feature and improves the navigation between Speed Dial, bookmarks and the Discover feature.
Now when you click to expand the tab menu (or press Ctrl+M on keyboard) and move the cursor over the tab names, you will also see the tab previews.
In addition, the navigation between Speed Dial, bookmarks and the Discover feature in Opera 27 has been moved to the bottom of the browser window so that you have more space at the top, and you can use the background of your choice without the previous fade-out effect.
For more details, see the changelog.
