- GCC compiler
- clang compiler, C++ 17
- 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)
- license management tool improvement (more accurate license compliance)
