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 v2025dev1 is the second development release of the Apertis v2025 stable release flow that will lead to the LTS Apertis v2025.0 release in March 2025.

This Apertis release is built on top of Debian Bookworm along with several customizations and it ships the latest Linux kernel 6.6.x series. Later releases in the v2025 channel will be tracking newer kernel versions up to the next LTS as well as Debian Bookworm Stable Channel.

Test results for the v2025dev1 release are available in the following test reports:

New features

Additional compiler warnings enabled by default

This new releases includes an Apertis specific profile for dpkg to enable additional compiler warnings. The use of this warnings can help to spot potential security issues in the packages being built, improving the quality of the system.

Build and integration

Add support for package testing

This release includes a new way for developers to includes tests to run on a Merge Request. The package testing in LAVA allows writing tests a part of the standard packing metadata, which are used by our GitLab infrastructure to run LAVA tests to ensure the proposed changes do not introduce any kind of regression in the supported hardware.

Support for image change history

Apertis now provides Change History Generator a tool to generate a changelog between images. Thanks to this tool, as part of daily builds a changelog is created which helps developers to track changes across different images.
