Core

Windows installer

Support for a Windows installer has been fully fleshed out and ready to be delivered, this means that Snapcraft will soon be able to run natively from Windows.

Improved build-base support

Support has been added to be able to use the build-bases keyword together with the following snap types:

• kernel
• snapd

Extensions

GNOME 3.28

An extension supporting GNOME 3.28 is part of this release, for discovery run

snapcraft list-extensions

Read about what it does by running

snapcraft extension gnome-3-28

Add it to an existing snapcraft.yaml by adding gnome-3-28 to the apps entry that requires it
and to see how it extends the snapcraft.yaml, at the root of the project, run

snapcraft expand-extensions

Plugins

colcon

New syntax is available to ignore packages:

- colcon-packages-ignore:
  (list of strings)
  List of colcon packages to ignore. If not specified or set to an empty
  list ([]), no packages will be ignored.

And a fix to enforce parallel building hints from snapcraft is now in place.

catkin

In contrast with colcon, a fix to enforce parallel building hints from snapcraft is also now in place.

rust

Support for properly building on s390x (natively) has been added.
