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 Timely?

Timely is grinding down the friction between tracked time and the tools it has to reconcile with.

Timely ships a steady biweekly changelog centered on three areas: AutoSheet reliability, bulk administrative actions, and integration fidelity with Jira, monday.com, Microsoft Teams, Gmail and Google Calendar. The recent run is corrective and administrative rather than expansive — duplicate client handling on import, undoable CSV imports and bulk moves, project pickers that default to your own work, and repeated fixes to capture gaps in Teams phone calls and high-volume Gmail days.

◆ 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

Timely is grinding down the friction between tracked time and the tools it has to reconcile with.

◆ Current state

Timely ships a steady biweekly changelog centered on three areas: AutoSheet reliability, bulk administrative actions, and integration fidelity with Jira, monday.com, Microsoft Teams, Gmail and Google Calendar. The recent run is corrective and administrative rather than expansive — duplicate client handling on import, undoable CSV imports and bulk moves, project pickers that default to your own work, and repeated fixes to capture gaps in Teams phone calls and high-volume Gmail days.

◆ Where it's heading

The product is being hardened for larger workspaces, where the old defaults broke down: full-workspace project lists became unusable, imports collided on names, and a single mis-click across many entries had no path back. Undo is becoming a standard affordance across destructive bulk actions. On the capture side, the recurring theme is that automatic tracking is only as good as its worst integration, and most effort goes to closing the cases where activity silently failed to appear.

◆ Prediction

Expect continued work on integration capture reliability and more bulk operations gaining the same ten-second undo pattern, rather than new tracking surfaces.
