This page documents the history of the OpenFact 5.5 series.

OpenFact 5.7.2

Released on October 6, 2026. This is the version bundled with openvox-agent 8.30.0.

A failed request for the EC2 metadata root listing is treated as no metadata again. Since 5.7.1 it raised instead, so on KVM and Xen guests without an EC2-compatible metadata service every fact resolution logged an error and facter exited with a non-zero status.

Please check the GitHub OpenFact release page for details on new features or bug fixes.

OpenFact 5.7.1

Released on September 23, 2026

EC2 metadata is published only when every metadata request succeeds. A timeout or error part-way through the lookup no longer leaves a partially populated ec2_metadata fact in the cache.
