What is Cobbler?

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

What is Routinator?

Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.

Cobbler's 3.3 branch adds Kerberos single sign-on to the web UI.

◆ Current state

Cobbler's public releases are all 3.3-branch backports. 3.3.10 adds Kerberos/GSSAPI single sign-on for the web UI through an Apache-terminated bridge and hardens the passthru authentication module against timing attacks. It follows the 3.3.8/3.3.9 pair, which brought openSUSE Leap 16 and Agama installer support, XCP-ng network installs and Python 3.13 support, and had to be re-cut after a CI publishing failure.

◆ Where it's heading

The branch is still gaining features aimed at enterprise data centres rather than winding down: new installer ecosystems in August, directory-backed single sign-on now. Authentication has been a recurring concern since the CVE-2024-47533 admin-API bypass. Releases continue to arrive as rollups from main.

◆ Prediction

Expect further 3.3.x rollups; whether the main line cuts a 3.4 is not visible from these entries.

Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default

◆ Current state

Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.

◆ Where it's heading

Having spent 2026 hardening the validator, the maintainers are now changing what operators get out of the box. Defaults moving toward ASPA and strictness put newer RPKI object types on equal footing with route origin validation.

◆ Prediction

A final 0.16.0 following one or more release candidates is the likely next step, as with 0.15.0.
