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.

What is Terragrunt?

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

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.

Terragrunt 1.2's last candidate finishes eleven experiments and locks down state buckets.

◆ Current state

Terragrunt v1.2.0-rc3, dated mid-October, is declared the final candidate: unless a blocker appears, v1.2.0 ships with its contents. The cycle completes eleven experiments, among them OCI, block-iteration, azure-backend and optional-hooks. Two changes need attention: base64gzip() now returns the Go 1.27 encoder's output, which can trigger resource replacements, and S3 bootstrapping no longer adds the RootAccess bucket policy statement.

◆ Where it's heading

The graduation model has repeated at a larger scale: six experiments in v1.1, eleven in v1.2. The candidates ran as stabilization, with fixes concentrated in the CAS, the catalog and the Provider Cache Server. Each breaking change also ships with an escape hatch, base64gzip_compat() or enable_bucket_root_access, which shows how seriously the project treats its 1.0 guarantees.

◆ Prediction

v1.2.0 final is the next release, since rc3 says only regression or urgent fixes will land first. It has not appeared in this feed in the 18 days since rc3.
