docling docling UPGRADE

Affected: >= 2.13.0 and < 2.74.0

Fixed in: 2.74.0

Safe to downgrade to: a release before 2.13.0

1. Check installed version

pip show docling

2. UPGRADE to 2.74.0

pip install --upgrade "docling>=2.74.0"

3. If no update is available yet, DOWNGRADE to a release before 2.13.0

pip index versions docling pip install "docling<2.13.0"

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.
