What is Robusta?

Robusta's recent releases patch its runner image rather than add features.

Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.

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.

5.0

Robusta's recent releases patch its runner image rather than add features.

◆ Current state

Robusta ships from an alpha channel, so alpha tags are its release line. The October tags are almost entirely image and CI work: 0.52.0-alpha patched high and critical CVEs in the runner image and removed orphaned Perl packages after a Debian upgrade, 0.52.0-alpha.1 backported OpenSSH, curl, expat and systemd fixes from Debian forky, and 0.54.0-alpha's notes cover only the removal of helm golden-file tests from CI. The last feature work in the feed was August's workflow trigger action and the signing-key leak fix.

◆ Where it's heading

Since late August the project has been treating its container image as the product surface that needs attention, with CVE patching handled by backporting packages from the next Debian release. The feature line that added workflow chaining, JSON logs and new alert sources has gone quiet in these entries. The 0.53 tag does not appear in the feed, so part of the picture may be missing.

◆ Prediction

Expect more runner-image CVE releases on the alpha line. Whether feature work on Holmes integration or alert sources resumes is not visible in these entries.

5.0

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.
