[Impact]
This release contains both bug-fixes and new features and we would like to make sure all of our supported customers have access to those improvements.

The most notable changes (besides usual bug-fixes) incoming in 0.103:
- Add YAML generator and Keyfile parser for NetworkManager YAML backend
- Add activation-mode parameter, needs systemd v248+ (LP: #1664844)
- Make use of systemd-networkd's restart/reconfigure commands
- Deprecate gateway4 & gateway6 in favor of defaults routes (LP: #1756590)
- Add io.netplan.Netplan.Generate() DBus method
- Changed the way of how unmanaged-devices are handled by NetworkManager
- Improve integration test suite (LP: #1922126)

See the changelog entry below for a full list of changes and bugs.

[Test Plan]
The following development and SRU process was followed:
https://wiki.ubuntu.com/NetplanUpdates

Netplan contains an extensive integration test suite that is ran using
the SRU package for each release. This test suite's results are available here:
http://autopkgtest.ubuntu.com/packages/n/netplan.io

A successful run is required before the proposed netplan.io package
can be let into -updates.

The netplan team will be in charge of attaching the artifacts and console
output of the appropriate run to the bug. Netplan team members will not
mark ‘verification-done’ until this has happened.

[Where problems could occur]
Netplan being a core package it could impact the whole networking stack of the operating system up to the point where servers would not be reachable anymore after a reboot, due to broken network config being generated by netplan at bootup. In order to mitigate the regression potential, the results of the aforementioned integration tests are attached to this bug:

Hirsute:
TBD groovy_amd64.log
TBD groovy_arm64.log
TBD groovy_armhf.log
TBD groovy_ppc64el.log
TBD groovy_s390x.log

Focal:
TBD focal_amd64.log
TBD focal_arm64.log
TBD focal_armhf.log
TBD focal_ppc64el.log
TBD focal_s390x.log

[Other Info]
The integration test logs will be attached to this bug, once the package has been accepted into -proposed and the tests have been executed on the real infrastructure.
