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 NetBird?

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

◆ 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.

NetBird's second v0.82 candidate keeps the MySQL removal and deprecates Rosenpass.

◆ Current state

NetBird is preparing v0.82 as a breaking release for self-hosters. Both candidates remove MySQL, require a migration to PostgreSQL, and move reverse-proxy access logs to their own store. rc.2 adds a Rosenpass deprecation notice with a replacement said to be in final testing, and tightens the SSH server: the root-login setting now applies to uid 0, and path-bearing locale, TERM and TZ values from clients are refused.

◆ Where it's heading

After v0.81 focused on device trust through certificate posture checks, v0.82 is about the management plane's storage and on hardening the built-in SSH server. Deprecating Rosenpass signals a change in how NetBird approaches post-quantum key exchange, though the entries do not name the replacement.

◆ Prediction

Expect v0.82.0 final with the MySQL removal intact, and a later release introducing the Rosenpass replacement.
