Opera 137.0.6015.0 developer update
Hello!
We’ve rolled out a new Opera Developer focused on stability and polish.
We fixed an issue where sessions could be wiped after a crash loop instead of simply skipping page loads, along with several crashes affecting the tab media list, tab collection moves, and Vertical Tabs-related crashes.
Split screen also got a round of improvements: links opened from split screen no longer create accidental single-tab islands, and split-screen tabs can once again be dragged into tab islands as expected.
Also, the React Settings now includes the missing JavaScript icons, points to the correct deep-link targets, and has a cleaner, more consistent sidebar width.
For a full list of changes check out our changelog.
Happy browsing!
