Apertis 17.09 Release

17.09 is the current stable development release of Apertis, a Debian/Ubuntu derivative distribution geared towards the creation of product-specific images for ARM (both in the 32bit ARMv7 version using the hardfloat ABI and in the 64-bit ARMv8 version) and Intel x86-64 (64-bit) systems.

This Apertis release is based on top of the Ubuntu 16.04 (Xenial) LTS release with several customization. Test results of the 17.09 release are available in the 17.09 test report.

Release downloads

Apertis 17.09 images
Intel 64-bit Intel 64 bit Minimal Image Intel 64 bit Target Image Intel 64 bit Development Image Intel 64 bit SDK Image

The minimal, target and development images are tested on the reference hardware (MinnowBoard MAX), but they can run on any UEFI-based x86-64 system. The sdk image is tested under VirtualBox.

New features

During this release the focus has been on bugfixes and improvements on the server infrastructure, but this does not mean that we lack new features: in particular, the application framework refactoring that has been started during the 17.06 cycle has landed in 17.09, and it is now able to work on system which lack direct access to a Btrfs filesystem. This is extremely useful for systems using flash-based filesystems and for containers-based setups where allowing the container privileged access to the file system may be undesirable. Compatibility with existing Btrfs-based setups is preserved, and they can be migrated transparently.


Apertis now works better in a container right out of the box, ensuring that AppArmor is enabled and disabling some filesytem-related services which are not needed inside a container.

Automation has been a recurring theme during this cycle, and now the developers documentation is automatically deployed on push. The main automation effort has been in defining more formally the whole release branching process and automate the most of it: this will allow us to make releases with more ease, reducing the chance of errors and focusing our efforts on making Apertis even more awesome.

Design and documentation

The Apertis platform guide now provides an high-level overview of what the Apertis platform is, which components compose it and what are the concepts that drive its development.

The Hello World section in the application developers guide has been updated to reflect the latest Eclipse UI.

If you want to run Apertis in a container, the setup instructions have been overhauled and clarified, and running an Apertis container under an Apertis system just takes a couple of minutes.

On the design front, the Inter-Domain Communications document now has some provisions for sharing large amount of static data as bulk transfers, such as firmware updates or map data for offline navigation.

Deprecations and ABI/API breaks


During this release cycle we have continued to mark obsolete or problematic APIs with the ABI break tag as a way to clear technical debt in future.

Mildenhall UI framework

The Mildenhall UI toolkit is deprecated in favour of other UI toolkits such as GTK+, Qt, or HTML5-based solutions
From the next release Apertis may no longer ship the Mildenhall UI toolkit, as the underlying Clutter library has been deprecated upstream for some years now.

Application framework

ribchester-full and canterbury-full are deprecated
From the next release Canterbury and Ribchester will only offer the APIs provided by the respective -core and the additional APIs offered by the -full packages will be dropped<


No known breaking changes are part of the 17.09 release.
