---

Removed

• Removed dependency on WinSAT disk benchmarking
→ Replaced with custom native implementation

---

Compatibility

• Removed support for 32-bit (x86) systems
→ Application is now 64-bit only

---

Notes

• Benchmark system now provides reliable real-world performance data
→ Ensures more stable and predictable backup operations
