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 ships AI Builder release 4 to its LTS line, with Gemini 4 Argon support.

ToolJet's LTS v3.20.250 brings AI Builder release 4 into the enterprise edition, with cancellation handling and Gemini 4 Argon as a model option; v3.20.248 added workspace MCP OAuth with SSO login. The beta line spent the week on Node 22.23.4 for the October security release, file-permission and license-check fixes, a page-panel crash fix, and an environment flag that limits ToolJet Database edits to admins.

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.

5.0

ToolJet ships AI Builder release 4 to its LTS line, with Gemini 4 Argon support.

◆ Current state

ToolJet's LTS v3.20.250 brings AI Builder release 4 into the enterprise edition, with cancellation handling and Gemini 4 Argon as a model option; v3.20.248 added workspace MCP OAuth with SSO login. The beta line spent the week on Node 22.23.4 for the October security release, file-permission and license-check fixes, a page-panel crash fix, and an environment flag that limits ToolJet Database edits to admins.

◆ Where it's heading

The AI Builder work that sat in beta is now reaching LTS customers, alongside MCP connections that respect SSO. Most other changes on both lines are security bumps and hardening, which fits a product selling to enterprises that run the LTS track.

◆ Prediction

Expect AI Builder to keep adding models and EE controls on LTS, and more admin-level permission flags like the database-edit restriction.
