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 Jackett?

Jackett in pure tracker-maintenance mode, daily domain and category updates only

Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.

Fission's release feed carries only RC tags, and none of them say what shipped

◆ 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.

Jackett in pure tracker-maintenance mode, daily domain and category updates only

◆ Current state

Jackett ships automated daily builds that consist almost entirely of tracker-library upkeep: domain alternatives, broken selectors, new categories for individual sites. The core indexer-proxy architecture is stable and unchanged. The only user-visible improvement in this window is hiding the API key on the dashboard.

◆ Where it's heading

The last 10 entries show no feature development — every commit is tracker registration data. Jackett's trajectory is entirely reactive to the torrent ecosystem: trackers move domains, change engines, and die; Jackett follows. There is no observable product initiative in this window.

◆ Prediction

The entries don't support a confident prediction about new feature direction. Daily tracker maintenance will continue as the primary output; any substantive change would come from outside this pattern.
