  • Netflix upgrade, youtube
  • GCC compiler
  • Maintainability - Dunfell 4 years ; Kirkstone 2 years ; CVE Dunfell is sill open (Refer Yocto mailing list), Upstream dunfell 3.1.24 has open CVE
  • Build time - reduce number of default dependency (make build faster in first/second time)
  • meta-rust is in core
  • software bill of material (security infrastructure)
  • share state - c standard. faster sstsate performance due to decompression standard cstd (twice faster than xz)
