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RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn.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.

What is Rancher?

Rancher's public feed is a build-tag stream: three branches bumped the same Go image on one afternoon

Rancher's public release feed is a tag stream rather than a changelog. The newest activity is three alpha tags cut within eight minutes on August 19 across the 2.12, 2.13 and 2.14 branches — two bumping the same SUSE Go base image to 1.25.13 via a bot, one pulling in a Fleet release candidate. The two maintenance releases before them, 2.12.12 and 2.11.16, each carry a single line pointing readers to the Prime documentation for the actual notes.

Argo Rollouts vs Rancher: editorial side-by-side

Argo Rollouts
INFRA · APIS
0.0

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

◆ Current state

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RCs largely on pipeline problems — rc3 explicitly ships no changes from rc2 — and its one architectural change was withdrawn.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.

◆ 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.

Rancher's public feed is a build-tag stream: three branches bumped the same Go image on one afternoon

◆ Current state

Rancher's public release feed is a tag stream rather than a changelog. The newest activity is three alpha tags cut within eight minutes on August 19 across the 2.12, 2.13 and 2.14 branches — two bumping the same SUSE Go base image to 1.25.13 via a bot, one pulling in a Fleet release candidate. The two maintenance releases before them, 2.12.12 and 2.11.16, each carry a single line pointing readers to the Prime documentation for the actual notes.

◆ Where it's heading

Four branches are now tagged in parallel, with 2.11 and 2.12 taking maintenance while 2.15 works through release candidates. The August alpha cluster is automated dependency traffic, not product work, and because notes for the supported branches live behind the Prime docs this feed will keep showing cadence without content. The only readable signals stay structural: which branches get tagged, and how far the 2.15 candidates have progressed.

◆ Prediction

The 2.15 line still looks closest to shipping, so the next visible move is a 2.15.0 general release tag — again with its notes pointing to Prime documentation rather than appearing here.
