Apertis is a Debian derivative distribution geared towards the creation of product-specific images for ARM (both the 32bit ARMv7 and 64-bit ARMv8 versions using the hardfloat ABI) and Intel x86-64 (64-bit) systems.

Apertis v2021.4 is the fifth stable release of the Apertis v2021 stable release flow. Apertis is committed to maintaining the v2021 release stream up to the end of 2022.

This Apertis release is built on top of Debian Buster with several customisations and the Linux kernel 5.10.x LTS series.

Test results for the v2021.4 release are available in the following test reports:

Point releases including all the security fixes accumulated will be published quarterly, up to v2021.7.
