## Summary
The OBS Studio 33.0 release includes a significant update to the Chromium Embedded Framework (CEF) used for browser sources and docks. It also implements a complete overhaul of the plugin loading architecture, separating first-party core plugins from third-party ones. Additionally, the update enables NVENC support on Arm64 and introduces various UI and stability improvements.

## Technical changes in OBS Studio 33.0
- **CEF Update**: Upgraded from version 127/6533 to 150/7871, affecting browser sources and docks.
- **Plugin Restructuring**: First-party plugins moved to a new 'core' folder; third-party plugins have updated installation paths. Legacy locations remain supported until version 34.0.
- **Hardware Acceleration**: Enabled NVENC support for Arm64 architectures.
- **UI/UX Improvements**: Enhanced source snapping in the preview, improved spinbox behavior for numeric values, and new visual indicators for snapping.
- **Platform Specifics**: Improved macOS Screen Capture transparency and Windows Window Capture naming.

## Why it matters
The plugin architecture change requires developers to adapt to new folder structures, though backward compatibility is maintained for one major version cycle.
