tinytag tinytag DOWNGRADE

Affected: 2.2.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.2.0

1. Check installed version

pip show tinytag

2. No fixed release: DOWNGRADE to a release before 2.2.0

pip index versions tinytag pip install "tinytag<2.2.0"

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.
