[Miroslav Vadkerti]

Testing Farm release 2025-01.7
https://docs.testing-farm.io/Testing%20Farm/0.1/releases/2025-01.7.html
was deployed on 2025-05-20.

*💔 Breaking changes*

This release is introducing hard memory limits on our worker containers,
possibly affecting some requests.
In case you hit the problem, you should discover that easily from the
request error.
The request error will link you to our error TFE-1
https://docs.testing-farm.io/Testing%20Farm/0.1/errors.html#TFE-1[ for
information how to deal with the problem.

*🐞 Bugfixes*

Testing Farm workers are now correctly enforcing a memory limit for worker
containers, greatly improving stability of all requests and mitigating
requests to get stuck in `running` state.
This can be breaking for some of the tests, see the 'Breaking changes'
section for details. (TFT-3333 https://issues.redhat.com/browse/TFT-3333
TFT-3334 https://issues.redhat.com/browse/TFT-3334 TFT-3338
https://issues.redhat.com/browse/TFT-3338 TFT-1762
https://issues.redhat.com/browse/TFT-1762)

Testing Farm now uses by default non-spot instances in AWS.
Due to the elevated usage of dedicated Testing Farm instances
https://docs.testing-farm.io/Testing%20Farm/0.1/test-request.html#_dedicated_instances,
the spot instances are terminated more frequently, causing random test
failures.
Until we are able to handle this problem gracefully, i.e. by automatically
restarting the affected requests, we decided to move the testing to
non-spot instances.
This will affect the cost of testing, but we do not expect the change to
have large impact.
We will be monitoring the situation going forward. (TFT-3371

A bug in upstream dramatiq https://github.com/Bogdanp/dramatiq/pull/707 was
found and patch in Artemis provisioner, greatly improving the stability of
provisioning and mitigate outages. (TFT-3331
https://issues.redhat.com/browse/TFT-3331)

The `pool` field under the provision step in tmt plans is now honored in
the single-host pipelines. (TFT-3368
