Key points
- CEF updated from 127/6533 to 150/7871.

- NVENC enabled on Arm64 platforms.
Core Framework Updates
OBS Studio 33.0 includes a significant update to its Chromium Embedded Framework (CEF), moving from version 127/6533 to 150/7871. This update, spanning from a July 2024 release to September 2026, primarily affects the underlying technology for browser sources and docks. While this is a backend change, users are encouraged to report any issues with browser sources.
Plugin System Overhaul
The plugin loading system has undergone a complete overhaul. First-party plugins are now located in a new 'core' folder, and third-party plugins have updated installation locations and folder structures. Existing third-party plugins will continue to load from legacy locations until OBS Studio 34.0, providing a transition period for developers and users.
Preview and UI Enhancements
Improvements have been made to how source snapping functions in the preview, including a new visual indicator. Sources now snap along their entire axis, rather than only when directly touching, and no longer snap to hidden sources. Additionally, spinboxes for number values have improved behavior, addressing issues with typing, display, and value updates.
Platform-Specific Changes and Fixes
NVENC encoding has been enabled for Arm64 architectures. The update also adds support for the newest NVIDIA Broadcast SDKs for audio and video effects. Other changes include a check for missing encoders when loading profiles, new hotkeys for audio monitoring, and adjustments to Safe Mode to prevent WebSocket Server startup. Bug fixes address issues with groups in Studio Mode, improved detection for fullscreen games, and better transparency handling for macOS Screen Capture.
