## Summary
The OBS Studio 33.0.0 Beta 5 release includes a significant backend update to the CEF used for browser sources and docks, moving from version 127 to 150. It also implements a new plugin loading system that separates first-party 'core' plugins from third-party ones. Additionally, the update enables NVENC on Arm64 and improves source snapping in the preview window.

## Technical changes in OBS Studio 33.0.0 Beta 5
- **CEF Update**: The underlying framework for browser sources and docks has been updated from 127/6533 to 150/7871.
- **Plugin Restructuring**: First-party plugins move to a 'core' folder; third-party plugins have new installation locations. Legacy locations remain supported until version 34.0.
- **Hardware Acceleration**: NVENC is now enabled for Arm64 architectures.
- **UI/UX Improvements**: Enhanced source snapping along axes and improved spinbox behavior for numerical inputs.
- **Compatibility**: Support for Ubuntu 24.04 has been removed.

## Why it matters
The plugin restructuring requires third-party developers to adapt to new folder structures before the release of version 34.0, while the CEF update may affect the stability of complex browser-based overlays.
