## Summary
Fedora Workstation 45 has been released, bringing the desktop environment to GNOME 51. This release focuses on desktop responsiveness, improved graphics pipeline standardization, and enhanced security through a new credential management architecture.

Key technical improvements include a redesigned frame scheduling system in Mutter to maintain stable frame rates during heavy workloads and the transition from proprietary NVIDIA interfaces to the standard GBM memory management path. Additionally, the release introduces oo7, a modern, sandboxed Secret Service provider designed to replace legacy keyring daemons for safer storage of API tokens and passwords.

## Technical improvements in Fedora 45
- **Graphics Pipeline:** Mutter features a reworked frame scheduling and delivery system to stabilize animations and transitions under high CPU/GPU load; additionally, legacy NVIDIA proprietary interfaces are replaced by the standard GBM memory management path for Wayland.
- **Security Architecture:** The new oo7 Secret Service provider replaces legacy keyring daemons with a compartmentalized, sandboxed service to protect application passwords and API tokens from rogue applications.
- **Files (Nautilus) & UI:** Nautilus implements non-blocking directory reloads to prevent interface freezes, while the File Previewer has been rebuilt using GTK 4 and libadwaita for better fractional scaling and theme integration.
- **Calendar Engine:** The Calendar application received a complete overhaul of its view-rendering engine to reduce latency when scrolling through dense schedules in Month View.

## Why it matters
The shift to GBM memory management improves Wayland stability and uniformity for users with NVIDIA hardware. Furthermore, the introduction of the sandboxed oo7 service sets a new security standard for how Linux desktop environments handle sensitive user credentials and application secrets.
