Opera 125.0.5727.1 developer update
Hello!
A fresh Opera update has just landed!
This build introduces our refreshed split-screen feature, now available for early testing. It’s still under development, so you may encounter a few bugs – but we’d love to hear what you think and what you discover as you try it out.
You can read more details in the full notes → Split Screen revamped in Opera Developer.
We’ve also included a fix for the issue with the Sonic theme not behaving as expected.
Known issue:
- A crash may occur when dragging a group of tabs between windows on macOS.

Enjoy the update, and let us know what you think!
