Parrot 4.11 release is powered by the latest LTS (Long-Term Support) Linux 5.10 kernel series for better hardware support and includes up-to-date core components based on the stable Debian GNU/Linux 10 Buster operating system repositories.
While Parrot 4.11 ships with Linux 5.10 LTS as the default kernel, the team plans to upgrade the system to the recently released Linux 5.11 kernel series since Parrot follows a rolling-release model. But they did not provide a time frame for doing so, and if you install Parrot 4.11, make sure you keep it up to date.
