Fission vs Skipper: at a glance
What is Fission?
Fission's release feed carries only RC tags, and none of them say what shipped
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
What is Skipper?
Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

◆ Current state
Every entry here is a release candidate — v1.22.0-rc1 and rc2, v1.23.0-rc1, v1.25.0-rc1 — with no final release appearing between them, and the version sequence skips 1.24 entirely. The bodies are whatever the tagging commit said, so what reaches this feed is a dependabot bump, a CLI tool-version refresh, a codegen sync explicitly labelled as having no functional change, and one entry that is nothing but links to an external release-highlights page. The actual release notes live on the project's documentation site, not here.
◆ Where it's heading
What can be read from these tags is infrastructure maintenance rather than product direction: Go dependency updates, helm and kind and skaffold and cosign version refreshes, and regenerated swagger and applyconfiguration files kept in sync with CEL and webhook validation comments in the core API types. That last one is the only entry hinting at anything structural — CEL-based validation on the API types implies declarative validation moving into the CRDs — but the commit itself changes only generated output.
◆ Prediction
This feed does not carry enough to predict product direction; until final releases or their notes appear here rather than only candidate tags, any read of where Fission is heading would be guesswork.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.
◆ Current state
Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.
◆ Where it's heading
The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.
◆ Prediction
The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
