Apertis 16.09 Release
16.09 is the current stable development release of Apertis, a Debian/Ubuntu derivative distribution geared towards the creation of product-specific images for ARM (ARMv7 using the hardfloat ABI) and Intel x86-64 (64-bit) systems.
Since this release Intel x86 32-bit systems are no longer supported, which includes devices like Zotac Z-BOX.
This Apertis release is based on top of the Ubuntu 16.04 (Xenial) LTS release with several customization. Test results of the 16.09 release are available in the 16.09 test report.

Routing information sharing for navigation services
Traprain is a new library introduced in Apertis 16.09 allowing navigation services to share routing information with third party applications. It enables applications to get the available routes to reach one or more destinations: for instance, with Traprain an application can request the routes to the nearby restaurants and sort them by estimated arrival time form the current location to help choosing the one to book.
See the Geolocation and navigation design for details.
Hardware accelerated support for Web contents
Apertis 16.09 ships with readily available support for accelerating Web contents (CSS3 transforms and animations, WebGL scenes) using the GPU efficiently under Wayland. This means that you can navigate the modern Web even with limited CPU resources and run WebGL scenes fully unleashing the power of your GPU.
Most of this work has now been landed upstream and we plan to submit the remaining optimizations soon.
Canterbury API for launching preferences
A new API (
has been implemented to allow applications to launch their preferences
support work, and unit tests for the implementation in Canterbury.
Automatic debug packages
A full rebuild of every package in the archive has been carried out to
be able to provide automatically-generated debug packages in the Apertis
repositories: this means that every package in the archive which ships
binary executables or libraries now automatically has an associated
-dbgsym package that contains the debug symbols for those binaries,
making debugging with
perf and other development
tools much easier and consistent.
Web engine stabilization
The move to WebKit2GTK+ has been a major improvement in Apertis 16.06: for this cycle we focused on smoothing any rough edge and making it even more stable. We fixed bugs in page rendering, touch events positioning, touch scrolling, browser drawing loop, contextual zoom to provide a modern and fast Web engine, fully integrated with the platform.
liblightwood 2 API review
A plan for submitting and reviewing the patches to change liblightwood from version 1 to version 2 (introducing new interface-based APIs) has been created, and an initial round of review on the core work and a couple of the ported widgets has been done. This work will continue into 16.12, now that the groundwork has been laid.
As test cases grows more sophisticated, improper memory management has been detected in various points. To provide the most stable environment even on long running session several memory management issues from leaks to double-free has been fixed mostly in libthornbury and mildenhall
Common code that could share a single implementation has been moved from each settings program to mildenhall-settings itself, improving the separation between the UI drawing logic and the settings backend. This reduces the chance of bugs, makes development easier and it's slightly more efficient overall.
List and UI customisation
Various updates have been made to the list design (not yet released) and to the UI customisation design, to cover some new use cases and to clarify how the list (or roller) interacts with adapters and with models, so that objects are stored once in a model, and can be displayed in multiple views simultaneously without being duplicated in memory.
We always want to make developing for Apertis as easy as possible, and this is another step in that direction.
Locale listing and switching
Minor updates have been made to the internationalization
design to clarify
the recommendation to use the
determining and changing the system locale. Updates have been made
upstream to gettext to allow it to be used to extract and translate
strings from ClutterScript files, which are used for UI design.
Continuous integration improvements
New packages have been added to the continuous integration loop, such as
apertis-designs. See the CI package
for the complete listing.
The on-going baseline effort has lead to several base packages to be
updated: it is worth mentioning the addition of
appstream-glib in the
target package set, the addition of the
license extensions to
hotdoc (already available
tag have all been
upgraded to the latest upstream versions) to the
set, and the addition of development tools such
speeding up the copying of images into boot media to the Apertis SDK.
Special attention has been put on packages composing the reference HMI,
all updated with the latest features and bugfixes. New packages such as
apertis-designs have also been added to
