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?

Observability lands on OpenTelemetry semconv in the LTS train

ToolJet runs two lines in parallel and both are in a steady groove. The LTS train picked up frontend and app observability built on OpenTelemetry semantic conventions plus primary and backup access, following a 3.20.212 release that carried the substantive feature batch — dynamic height across Timeline, Filepicker, Reorderable List, RadioButtonV2 and Tags, dynamic number formats on Currency Input, camera flip on mobile, and AI build notifications. The beta line is mostly fixes and LTS cherry-picks.

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.

Observability lands on OpenTelemetry semconv in the LTS train

◆ Current state

ToolJet runs two lines in parallel and both are in a steady groove. The LTS train picked up frontend and app observability built on OpenTelemetry semantic conventions plus primary and backup access, following a 3.20.212 release that carried the substantive feature batch — dynamic height across Timeline, Filepicker, Reorderable List, RadioButtonV2 and Tags, dynamic number formats on Currency Input, camera flip on mobile, and AI build notifications. The beta line is mostly fixes and LTS cherry-picks.

◆ Where it's heading

Most releases are small and corrective, with feature work collecting into occasional larger LTS drops. The recurring themes are component sizing, which appears in nearly every release, and enterprise-operations work — global data source certificates, automated RDS SSL setup, CVE patching, and now standards-based observability. It reads as a platform hardening for self-hosted enterprise deployments.

◆ Prediction

Expect the dynamic-height and sizing pass to continue across the remaining widgets, and the beta line's AI datasource integrations to graduate into the LTS train. Standardizing on OTel semconv suggests exported traces and metrics for customer-run dashboards next.
