The latest version is 3.1. Feel free to give it a try using one of our builds:

• Docker image: https://hub.docker.com/r/ripencc/rpki-validator-3-docker
• RPM: https://ftp.ripe.net/tools/rpki/validator3/prod/centos7/repo/
• DEB: https://ftp.ripe.net/tools/rpki/validator3/prod/deb/
• Tarball: https://ftp.ripe.net/tools/rpki/validator3/prod/generic/

Or follow the step-by-step installation instructions.

Latest changes in 3.1:

• Prometheus endpoint on /metrics for both validator and rtr-server.
• JDK 11 support
• Minimize memory consumption and disk requirement by dropping Hibernate/H2 database, and use Xodus https://github.com/JetBrains/xodus as persistence instead.
• Improve responsiveness, set default RPKI object clean up grace period to 48 hours (used to be 7 days).
• Store all the ignore filters and white lists in a slurm.json file instead of the database, so now the database can be deleted any time without losing any user-configured data.

We keep a change log of changes that are relevant to our users and include this in the build.

More information on the RPKI Validator 3 project is documented in the wiki.
