# Apertis 18.06 Release

**18.06** is the current stable development release of **Apertis**, a
Debian/Ubuntu 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.

This Apertis release is based on top of the Ubuntu 16.04 (Xenial) LTS
release with several customizations. Test results of the 18.06 release
are available in the [18.06 test
report]( {{< ref "/qa/weekly_tests/18.06/20180624.md" >}} ).

### Release downloads

| [Apertis 18.06 images](https://images.apertis.org/release/18.06/) |
| ----------------------------------------------------------------- |
| Intel 64-bit                                                      |
| ARM 32-bit (U-Boot)                                               |
| ARM 32-bit (MX6q Sabrelite)                                       |
| ARM 64-bit (U-Boot)                                               |

The Intel `minimal`, `target` and `development` images are tested on the
[reference hardware (MinnowBoard MAX)]( {{< ref "/reference_hardware/_index.md" >}} ),
but they can run on any UEFI-based x86-64 system. The `sdk` image is
[tested under VirtualBox]( {{< ref "/virtualbox.md" >}} ).

#### Apertis 18.06 repositories

` $ deb `<https://repositories.apertis.org/apertis/>` 18.06 target helper-libs development sdk hmi`

## New features

### Official supported images for i.MX6 Sabrelite boards

The [i.MX6
Sabrelite]( {{< ref "/reference_hardware/imx6q_sabrelite_setup.md" >}} ) board
is now officially supported by the main image set with the new
`mx6qsabrelite` image variant.

The headless minimal images are fully supported, while images with the
full grahics stack are still in the works.

This means that anybody can deploy the publicly available
`mx6qsabrelite` system images on i.MX6 Sabrelite and start experimenting
with Apertis on their hardware.

### Linux kernel v4.14 available on all the supported platforms

The 4.14 LTS version of the mainline Linux kernel is now used by every
supported platform. Previously different releases were used on each
platform, ranging from 3.14 to 4.4 and 4.9, all build from different
source packages.

Apertis now offers support of all the supported platforms using kernels
build from a single, common source packages, providing an updated and
supported baseline and simplifying maintainance and development of new
features.

### SDK for platform development

The focus for the Apertis SDK so far has been centered on application
development but from this release we started to make it more useful for
platform developers that want to hack to the base Apertis system. In
this release new packages for the SDK have been made available,
configuration tweaks have been applied and several little nuisances have
been addressed.

### Code hosting on GitLab

All the Apertis code repositories have been migrated to the new [GitLab
instance hosted by the Apertis team](https://gitlab.apertis.org/public).

GitLab brings Apertis many benefits over the previous setup:

  - better web UI
  - site-wide source code search
  - the availability of a merge-request based review workflow
  - finer grained access controls
  - built-in continuous automation

Phabricator is still used for task tracking and for patch review. A
GitLab merge-request based review workflow to replace the latter is
being defined.

The [CGit code hosting](https://git.apertis.org/) service has been
obsoleted and is now read-only. Redirects have been put in place to
route requests from the old service to tne new one.

### Closed the CI loop by automatically opening issues on automated test failures

A way to automatically file new bugs and update them when a test is
failing has been designed and its implementation is being finalized.

A new service gets tests results out of LAVA, processes them and then
connects to the Phabricator APIs to open new task or update existing
ones.

Managers can now rely on the tasks on Phabricator to check the health of
the testsuite and developers get timely updates about the latest status
of failing tests.

## Quality Assurance

### Testcase prioritization

A priority level has been assigned to each
[testcase]( {{< ref "/qa/test_cases/_index.md" >}} ) in order to better schedule their
execution, to clearly identify release blockers and to prioritize
maintainance and improvements.

### Testcases ported to run on the OSTree images

More testcases have been ported to avoid dependencies in a way that they
can be run without installing new packages on the base image.

This has two benefits:

  - makes testing more valuable by not perturbing the actual base image
  - allows those tests to be executed on OSTree images

### Test ADE as part of the continuous test rounds

Tests exercising cross-building and remote debugging using the ADE
(Apertis Development Environment) tool are now part of the [weekly test
reports]( {{< ref "/qa/weekly_tests/_index.md" >}} ).

## Build and integration

### Image recipes cleanups

The [Apertis image
recipes](https://gitlab.apertis.org/infrastructure/apertis-image-recipes)
have seen several cleanups and improvements in order to make them
simpler, faster, more robust, and easier to maintain and customize.
Further improvements are planned and being worked on.

## Design and documentation

### All documents available in PDF format

Line-numbered PDF versions of the [design
documents](https://designs.apertis.org/) are available for download in
order to provide a better offline reading experience.

To get them, replace the `.html` extension in the URL with `.pdf`, for
instance
[system-updates-and-rollback.html](https://designs.apertis.org/latest/system-updates-and-rollback.html)
becomes
[system-updates-and-rollback.pdf](https://designs.apertis.org/latest/system-updates-and-rollback.pdf).

### Improving storage and handling of the definitions and results of testcases

A new set of concept documents has been worked on to address some
shortcomings in the current infrastructure about the best way to store
testcase definitions, to handle test results and to process those
results to provide reliable reporting.

### Improvement to the *System updates and rollback* document

A list of use-cases has been added to the [System updates and
rollback](https://designs.apertis.org/latest/system-updates-and-rollback.html)
design document in order to guide the evaluation of features and
approaches.

Several other improvements and clarifications have been applied to the
document based on the feedback gathered.

### Security aspects of OSTree

The [updates and rollback design
document](https://designs.apertis.org/latest/system-updates-and-rollback.html%7CSystem)
has been updated to cover the security aspects of OSTree, describing how
updates are verified and how it relates to other technologies that can
be used in verified boot solutions.

### Examples of key OSTree commands for Apertis images

A few OSTree commands have been collected in
[Docs/OSTree]( {{< ref "/docs/ostree.md" >}} ) to provide a reference of
important operations for developers:

  - updating the system
  - list locally available deployments
  - rolling back to previous releases
  - enabling temporary read-write access to the system

## Deprecations and ABI/API breaks

### Deprecations

During this release cycle we have continued to mark obsolete or
problematic APIs with the [ABI
break](https://phabricator.apertis.org/tag/abi_break/) tag as a way to
clear technical debt in future.

#### Development images

<dl>

<dt>

The `development` image type is deprecated in favour of extending the
`target` image type

<dd>

From the next release Apertis will no longer ship `development` images,
covering the use-cases addressed by them by adding the needed packages
to the `target` image type.

</dl>

#### Mildenhall UI framework

<dl>

<dt>

The Mildenhall UI toolkit is deprecated in favour of other UI toolkits
such as GTK+, Qt, or HTML5-based solutions

<dd>

From the next release Apertis may no longer ship the Mildenhall UI
toolkit nor any accompanying libraries, as the underlying Clutter
library has been deprecated upstream for some years now.

</dl>

#### Application framework

<dl>

<dt>

`ribchester-full` and `canterbury-full` are deprecated

<dd>

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

</dl>

### Breaks

<dl>

<dt>

SSH addresses for Git repositories need to be manually updated

<dd>

With the move to GitLab the location of the Apertis Git repositories has
changed: HTTP(S) redirects have been put in place to transparently route
requests, but no similar mechanism is available for SSH, so SSH remotes
will need to be updated manually

<dt>

`xterm` is no longer available on the SDK images, replaced by
`xfce4-terminal`

<dd>

The lack of support for "modern" features like supports copy-and-paste
in <code>xterm<code> confused some users and it has been replaced by
`xfce4-terminal`

</dl>

## Infrastructure

### Apertis infrastructure tools

The Apertis Debian Stretch tools repositoriy provides packages for
`git-phab`, `lqa`, Debos and deps, LAVA v2, OBS 2.7, `ostree-push` and
`jenkins-job-builder`:

` $ deb `<https://repositories.apertis.org/debian/>` stretch tools`

### Images

Image daily builds, as well as release builds can be found at:

` `<https://images.apertis.org/>

Image build tools can be found in the Apertis tools repositories.

### Infrastructure overview

The [Image build infrastructure
document](https://designs.apertis.org/18.06/image-build-infrastructure.html)
provides an overview of the image building process and the involved
services.
