collerek ormar UPGRADE

Affected: >= 0.9.9 and < 0.23.0

Fixed in: 0.23.0

Safe to downgrade to: a release before 0.9.9

1. Check installed version

pip show ormar

2. UPGRADE to 0.23.0

pip install --upgrade "ormar>=0.23.0"

3. If no update is available yet, DOWNGRADE to a release before 0.9.9

pip index versions ormar pip install "ormar<0.9.9"

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
