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 Infisical?

PAM and PKI now take up most of the lines in Infisical's release notes.

Six releases in two weeks, each a flat PR list with no narrative. The recurring feature work is privileged access management — Redis account types and web access, filling account fields from a pasted connection string, machine identity access — and PKI, which gained AWS Private CA as an issuing authority and SCEP enrollment for Microsoft Intune. Secret management itself mostly appears as rotation coverage for Cloudflare API tokens and R2 access keys.

◆ 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.

PAM and PKI now take up most of the lines in Infisical's release notes.

◆ Current state

Six releases in two weeks, each a flat PR list with no narrative. The recurring feature work is privileged access management — Redis account types and web access, filling account fields from a pasted connection string, machine identity access — and PKI, which gained AWS Private CA as an issuing authority and SCEP enrollment for Microsoft Intune. Secret management itself mostly appears as rotation coverage for Cloudflare API tokens and R2 access keys.

◆ Where it's heading

Infisical is assembling a credential platform rather than a secrets store, and it is doing so without a single headline release — each pillar arrives as two or three PRs per version. PKI is furthest along: issuing from an external AWS authority and enrolling devices through Intune puts it in territory previously held by dedicated certificate products. A third thread, the agent proxy, is accumulating the parts a product needs before launch — a Google Workspace service template, last-used timestamps, and adoption telemetry for proxied services.

◆ Prediction

The agent proxy is the thread most likely to get a real announcement; service templates and usage telemetry landing now are the groundwork a launch requires.
