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)
license management tool improvement (more accurate license compliance)
Kirkstone need minimum 4.x kernel (refer systemd)
linux_kernel_header does not mandate

Migrate RPI4 32 bit to Yocto 4.0
support@rdkcentral.com
To tackle the build issues from moving one version to another, we have decided to split the problem into different subtasks. So instead of building a complete image at one go, we have planned for the generation of the following images:
These images need to be tested in cmf, to ensure that nothing has broken the existing system.
In order to provide a smooth transition without disturbing the existing branch, we have created a branch called `feature-kirkstone` for non-OE layers and another branch called `rdk/kirkstone` for OE layers and 2.2 revision for bitbake
