What is Apache CloudStack?

CloudStack ships two LTS branches in lockstep and publishes nothing but pointers

Apache CloudStack maintains 4.20 and 4.22 as parallel LTS lines and tags them together — 4.20.3.1 and 4.22.1.1 were cut 49 minutes apart, both with bodies that say only which branch was tagged. The release entries themselves carry no content: the standard body is a set of links to release notes, install, upgrade, admin, and API docs hosted elsewhere. The one exception is the security releases, where the CVE list is written inline.

What is Gloo Gateway?

One status-churn fix, shipped to four maintenance branches inside forty minutes.

Gloo maintains four release lines at once — 1.18, 1.19, 1.20 and 1.21 — plus a 1.22 beta series, and fixes are fanned across all of them together. On 5 August, v1.18.41, v1.19.20, v1.20.22 and v1.21.13 were cut within forty-five minutes of each other carrying the same Kubernetes Gateway report-churn fix and the same Go, gRPC and kubectl dependency bumps.

CloudStack ships two LTS branches in lockstep and publishes nothing but pointers

◆ Current state

Apache CloudStack maintains 4.20 and 4.22 as parallel LTS lines and tags them together — 4.20.3.1 and 4.22.1.1 were cut 49 minutes apart, both with bodies that say only which branch was tagged. The release entries themselves carry no content: the standard body is a set of links to release notes, install, upgrade, admin, and API docs hosted elsewhere. The one exception is the security releases, where the CVE list is written inline.

◆ Where it's heading

The pattern is stable and unlikely to change: maintenance releases on both LTS lines, a regular release on its own cadence, and security fixes backported across every supported branch at once. Because the feed only becomes descriptive when an advisory forces detail into it, the visible record of this project skews heavily toward vulnerabilities — seven CVEs across backups, templates, and cross-tenant Proxmox access in May alone — and says almost nothing about features.

◆ Prediction

Expect the paired-branch tagging to continue, with the next informative entry being a security release rather than a feature one. Nothing in this feed supports a claim about where CloudStack's capabilities are heading; that information lives in the release notes it links to.

5.0

One status-churn fix, shipped to four maintenance branches inside forty minutes.

◆ Current state

Gloo maintains four release lines at once — 1.18, 1.19, 1.20 and 1.21 — plus a 1.22 beta series, and fixes are fanned across all of them together. On 5 August, v1.18.41, v1.19.20, v1.20.22 and v1.21.13 were cut within forty-five minutes of each other carrying the same Kubernetes Gateway report-churn fix and the same Go, gRPC and kubectl dependency bumps.

◆ Where it's heading

The recurring theme is translation correctness under Kubernetes Gateway API — specifically, bugs where the translator's internal state does not behave the way its callers assume. The report-churn fix found equality checks comparing maps of pointer values, so identical output registered as changed on every recompute. The delegateOptions fix in beta11 found RouteOptions assigned by reference from the snapshot, so merging parent Virtual Service options mutated shared protos and contaminated every other route for the rest of the cycle. Both ship with the same instinct for caution: the second one is gated behind GLOO_ISOLATE_DELEGATE_ROUTE_OPTIONS so operators can revert.

◆ Prediction

The 1.22 beta line will keep collecting Gateway API translation fixes ahead of a stable release, and each one that matters will be backported across all four maintenance branches on the same day, as this window shows twice.
