What is Terragrunt?

Terragrunt graduated six experiments at once and has spent three candidates stabilising them

Terragrunt is running the v1.1.0 release-candidate cycle, now at rc3. The first candidate completed six experiments simultaneously — stack-dependencies, a content-addressable store, a catalog redesign, mark-many-as-read, opt-out-auth and DAG queue display. The two candidates since have added only bug fixes for those features plus improvements to how releases are published and verified.

What is Argo Rollouts?

An RC-only feed where 1.9's headline change was reverted before it shipped.

Every entry in this window is a release candidate; no GA tag appears at all. The 1.9 line spent three RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn. That change would have narrowed .status.selector to report only the stable ReplicaSet for traffic-routed canaries so HPA stopped counting canary pods in its desired-replica math. The 1.10.0-rc1 notes are dominated by build and dependency work.

Terragrunt graduated six experiments at once and has spent three candidates stabilising them

◆ Current state

Terragrunt is running the v1.1.0 release-candidate cycle, now at rc3. The first candidate completed six experiments simultaneously — stack-dependencies, a content-addressable store, a catalog redesign, mark-many-as-read, opt-out-auth and DAG queue display. The two candidates since have added only bug fixes for those features plus improvements to how releases are published and verified.

◆ Where it's heading

The experiment-graduation model is doing what it is supposed to: features developed behind flags land together in one minor, and the candidate cycle is purely stabilisation. The release-publishing and verification work appearing in rc2 suggests supply-chain provenance is being treated as release-blocking rather than as a follow-up.

◆ Prediction

With three candidates carrying identical feature lists, v1.1.0 final is the likely next release, followed by a fresh batch of experiments opening for v1.2.

◆ Current state

That change would have narrowed .status.selector to report only the stable ReplicaSet for traffic-routed canaries so HPA stopped counting canary pods in its desired-replica math. The 1.10.0-rc1 notes are dominated by build and dependency work.

◆ Where it's heading

The visible direction is operational rather than behavioural: notifications broadened to Teams workflows and NATS.io, a build system parameterized for company forks, CI skipped for docs-only changes, a move to pnpm. The selector revert says the project would rather live with awkward HPA math than break autoscaling for existing users, so progressive-delivery mechanics stay where they are.

◆ Prediction

1.10.0 looks likely to land close to rc1 — dependency, CVE and notification work with no controller-semantics change — and the HPA selector question stays open unless it returns behind an opt-in flag.
