What is Dragonfly?

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

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.

5.0

Dragonfly speeds up slot lookups on 2.0 as its cluster-mode fixes keep coming.

◆ Current state

Dragonfly maintains two incremental lines, 1.40 and 2.0, with small targeted releases. The 2.0 line has fixed dropped writes during slot migration and moved experimental slot-based sharding to Fibonacci hashing. i2.0.6 on October 30 makes GetSlotInfo faster, another cluster-mode refinement.

◆ Where it's heading

The 2.0 line is maturing through cluster and migration work, while 1.40 gets targeted performance backports. Release cadence has slowed from paired weekly builds to occasional single fixes.

◆ Prediction

Expect further 2.0.x builds focused on cluster mode and slot migration; whether scope-based memory tracking gets switched on is still unclear.

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.
