Rancher vs Terragrunt: at a glance
What is Rancher?
Three Rancher branches went from rc1 to final in a day, with nothing but a Dashboard ref bump.
Rancher's latest round cut v2.11.19, v2.12.15 and v2.13.11 as finals on October 29, one day after their rc1 tags. Each tag body shows only the automated Dashboard ref update. Alongside them, v2.15.3 reached rc2 and v2.14.7 reached rc1, so the two newest lines are still in candidate stage.
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.

Rancher
5.0INFRA · APIS
Three Rancher branches went from rc1 to final in a day, with nothing but a Dashboard ref bump.
◆ Current state
Rancher's latest round cut v2.11.19, v2.12.15 and v2.13.11 as finals on October 29, one day after their rc1 tags. Each tag body shows only the automated Dashboard ref update. Alongside them, v2.15.3 reached rc2 and v2.14.7 reached rc1, so the two newest lines are still in candidate stage.
◆ Where it's heading
The feed keeps publishing the branch matrix rather than what shipped in it. The older branches move through quickly on automation while the newest lines take extra candidates, the same split as the August round. What changed in these releases is not visible in the entries, so the pattern shows process rather than product direction.
◆ Prediction
Expect v2.15.3 and v2.14.7 finals to follow once their candidates clear. Nothing in these tags indicates what they contain.
Terragrunt
5.0INFRA · APIS
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.
