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 fixes two silent data-loss bugs — body truncation on large requests and multi-value header drops.
Skipper is in a steady maintenance phase: the two meaningful releases this period are correctness fixes for a silent body-truncation bug in the io matcher (large request bodies dropped silently beyond the max buffer size) and a cookie-deleting bug where modRequestHeader/modResponseHeader only applied regex rewrites to the first value of a multi-valued header. Both are proxy correctness issues where the visible behavior was incorrect responses, not errors.

◆ 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

Skipper fixes two silent data-loss bugs — body truncation on large requests and multi-value header drops.
◆ Current state
Skipper is in a steady maintenance phase: the two meaningful releases this period are correctness fixes for a silent body-truncation bug in the io matcher (large request bodies dropped silently beyond the max buffer size) and a cookie-deleting bug where modRequestHeader/modResponseHeader only applied regex rewrites to the first value of a multi-valued header. Both are proxy correctness issues where the visible behavior was incorrect responses, not errors.
◆ Where it's heading
The release cadence is high but the surface area of recent changes is narrow: dependency bumps, documentation corrections, and targeted correctness fixes. Skipper is a mature, production-stable L7 proxy — the development pattern reflects that. The v0.28.x branch is moving ahead of the v0.27.x LTS track simultaneously.
◆ Prediction
The entries don't show architectural moves in the near term. The next meaningful Skipper releases will likely continue in this pattern: correctness fixes for edge-case proxy behaviors that bite production users, with occasional dependency security updates.
