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 ToolJet?

ToolJet's beta line is stacking AI datasource connectors while LTS takes the security work.

ToolJet runs two release trains in parallel and they carry different cargo. The beta line's 3.21.57 is the substantive release in this window: datasource tagging and mentions with HubSpot, ServiceNow, and QuickBooks AI integrations, link and password expiry controls, a group-based user filtering endpoint, and a clearForm action on the Form widget. The LTS line is absorbing security and stability — two-factor authentication, cross-tenant database vulnerability fixes, CSV import — plus a steady drip of builder fixes that get backported between the trains.

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.

ToolJet's beta line is stacking AI datasource connectors while LTS takes the security work.

◆ Current state

ToolJet runs two release trains in parallel and they carry different cargo. The beta line's 3.21.57 is the substantive release in this window: datasource tagging and mentions with HubSpot, ServiceNow, and QuickBooks AI integrations, link and password expiry controls, a group-based user filtering endpoint, and a clearForm action on the Form widget. The LTS line is absorbing security and stability — two-factor authentication, cross-tenant database vulnerability fixes, CSV import — plus a steady drip of builder fixes that get backported between the trains.

◆ Where it's heading

The AI surface is being wired into enterprise systems of record rather than kept as a generic assistant, and datasource mentions suggest the intent is for AI features to reference specific connected sources instead of operating blind. Meanwhile the LTS train is where multi-tenant hardening lands, which is what a self-hosted product does when its user base skews toward customers running their own instances. Expect the same change to appear twice in the feed, once per train.

◆ Prediction

Expect the AI connector catalog to keep widening toward enterprise SaaS, since three major systems of record were added in a single beta release. The 3.21 features will follow the usual path into the LTS line once they stabilize.
