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 v2020.1 is the second stable release of the Apertis v2020 release flow. Apertis is committed to maintaining the v2020 release stream until September 2021.

This Apertis release is built on top of Debian Buster with several customisations.

Test results for the v2020.1 release are available in the following test reports:

Point releases including all the security fixes accumulated will be published quarterly, up to v2020.7.

Deprecations and ABI/API breaks

The GitLab-CI image building pipeline will replace the Jenkins pipeline

The GitLab-CI imabe building pipeline is now available on the v2020 branch as well. It currently co-exist with the Jenkins pipeline which is still the reference pipeline for this Apertis release.

During the v2020.2 cycle the project will evaluate having the GitLab-CI pipeline as the reference pipeline, putting the Jenkins pipeline into maintenance mode.
