Hello!

We’ve rolled out a new Opera Stable release. Chromium is updated to 155.0.8059.85 and the major version is bumped to 139.

On the feature side, we’ve launched Web AI: local, browser-powered AI.

We’ve also brought HTML in Canvas to the browser via the new #canvas-draw-element flag in Early Bird.

Other changes in this release:

• Make Opera Yours 2.0 (the start-page widget for personalizing Opera) is now enabled on all streams, with a refreshed welcome state, dynamic top themes from the Theme Gallery, and a new hover design.
• Sidebar and side panel polish: no more 4px strip after auto-hide, no more ChatGPT/Claude panels reopening on their own.
• Tabs: updated separator colors, fixed “New Tab” alignment, URL drag-and-drop from the bookmark bar on Linux.
• Setting: favicons on settings pages, restored Opera account sync, tidier Third-party cookies UI.
• Video: fixed H.264 encoder errors and Paramount+ Error 100 playback failures.
• Stability: crash fixes across the installer, DevTools, web forms, address bar, side panel, and tab handling.

You can find the full list in the changelog.
