Opera 138 developer
Hello!
We’ve rolled out a new Opera Developer release (version: 138.0.6038.0) with a Chromium bump (updated to 153.0.8010.5), and a large batch of fixes across the new React settings, Vertical Tabs, and overall stability.
Much of this release focused on improving the new React settings. Deep links now open the correct pages, sync works again with open tab details restored, and search updates the URL while keeping phrases intact. We also fixed several smaller issues, including missing labels and icons, hidden Early Bird features, blocker exceptions, VPN Pro status styling, spell check languages, and layout inconsistencies.
Vertical Tabs now save their collapsed/expanded state per window, with new windows inheriting the last open window’s state. We also fixed tab search with hidden sidebars, dropdown styling on Windows, and tab clicks after switching layouts.
We also added popup warnings about sound use in Easy Setup and Settings.
Known issues:
- Speed Dial folders cannot currently be created. We’re investigating the issue.

Happy browsing!
