The release of the new version of mobile platform LineageOS 21, which arrives Built on the Android 14 codebase, along with which the formation of builds for LineageOS 20 and 18.1 has also continued.

In this new version that is presented of LineageOS 21 Security patches have been integrated from January 2023 to February 2024, which were also included in version 18.1 It is worth mentioning that the continuation of support for LineageOS 18.1, based on Android 11, is due to the change that occurred from Android 12, where the platform began to use eBPF for filtering packages.

This led to the discontinuation of support for many older devices due to the unavailability of a Linux kernel with eBPF (4.9+) support for these devices. Although eBPF support was supported for devices with kernel 4.4, porting is difficult for devices with Qualcomm MSM8996 SoC, based on kernel version 3.18.
