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.

What is Traefik?

Traefik v3.8 rc.1 is a Gateway API release; v2.11 keeps getting security patches.

Traefik runs two lines. v3.8.0-rc.1 (2026-10-30) is mostly Kubernetes Gateway API work: ListenerSet support, client certificate validation, backend TLS policy for gRPC and TLSRoute, and TCPRoute consumed through its v1 version with Gateway API v1.5.x support dropped. It also adds per-router responding timeouts and an ACME option to reuse private keys. The v2.11 line keeps weekly-to-biweekly patches: 2.11.61 adds an entry-point limit on request header values and fixes a backend connection leak for NTLM and Kerberos.

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.

5.0

Traefik v3.8 rc.1 is a Gateway API release; v2.11 keeps getting security patches.

◆ Current state

Traefik runs two lines. v3.8.0-rc.1 (2026-10-30) is mostly Kubernetes Gateway API work: ListenerSet support, client certificate validation, backend TLS policy for gRPC and TLSRoute, and TCPRoute consumed through its v1 version with Gateway API v1.5.x support dropped. It also adds per-router responding timeouts and an ACME option to reuse private keys. The v2.11 line keeps weekly-to-biweekly patches: 2.11.61 adds an entry-point limit on request header values and fixes a backend connection leak for NTLM and Kerberos.

◆ Where it's heading

Feature work sits entirely on v3, and Gateway API is its center: the release tracks upstream versions and drops older ones, so Traefik is betting on Gateway API as its main Kubernetes interface. v2.11 is a security branch; five advisories in 2.11.58 and a CVE in 2.11.60 show it still gets real fixes.

◆ Prediction

Further 3.8 release candidates and then a final 3.8.0 are the likely next steps, with v2.11 patches continuing in parallel.
