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 ships a daily build to keep hundreds of torrent indexers working as sites move and close.

Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.

◆ 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.

5.0

Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.

◆ Current state

Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.

◆ Where it's heading

The work is entirely maintenance. Its value depends on keeping up with a tracker ecosystem where sites change domains and layouts weekly. Where possible, the project is moving definitions to sturdier integrations, such as switching world-of-tomorrow to its Torznab API and retiring trackers that moved to direct downloads.

◆ Prediction

Expect the daily cadence to continue, with more trackers moved to API-based definitions and more dead sites removed. Core changes stay rare.
