What is Hanko?

Hanko maps SAML and OIDC attributes into custom claims, a step toward enterprise SSO.

Hanko is a passkey-first authentication platform, open source or cloud-hosted. October's update lets teams bring attributes from SAML and custom OIDC connections into Hanko as custom claims, configured in the Cloud Console. Earlier 2026 releases added Firebase password hash import, inactivity logouts, session transparency and stronger passcode policies.

What is Transmission?

Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.

The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.

Hanko maps SAML and OIDC attributes into custom claims, a step toward enterprise SSO.

◆ Current state

Hanko is a passkey-first authentication platform, open source or cloud-hosted. October's update lets teams bring attributes from SAML and custom OIDC connections into Hanko as custom claims, configured in the Cloud Console. Earlier 2026 releases added Firebase password hash import, inactivity logouts, session transparency and stronger passcode policies.

◆ Where it's heading

Hanko is filling in what enterprise customers expect from an identity provider: SSO attribute mapping, session controls and migration paths from incumbents. Releases arrive monthly or less, each with a narrow feature.

◆ Prediction

More enterprise SSO features, such as directory sync or role mapping from claims, are the likely next additions; the entries do not confirm a timeline.

Transmission rewrote its RPC API to JSON-RPC 2.0 — then the 4.1 beta train stalled.

◆ Current state

The whole visible history is the 4.1.0 beta series, running from December 2024 to January 2026 and developed in parallel with the 4.0.x bug-fix line since 2023. Across those betas the client picked up sequential downloading, a selectable µTP-versus-TCP preferred transport, proxy support for web connections, IPv6 and dual-stack UDP trackers, native platform icons, and a JSON-RPC 2.0-compliant RPC API with snake_case unified across RPC and settings.json. Feature freeze was declared at beta.5 in January 2026, and nothing has shipped since.

◆ Where it's heading

The interesting work is at the integration boundary, not in the download engine: the RPC surface has been standardised and renamed, and beta.5 was largely spent repairing what those changes broke, including backwards-incompatible keys accidentally written into settings files. That is the cost profile of an API migration in a project with a large ecosystem of third-party remotes. With feature freeze held for seven months and no 4.1.0 final, the release is late relative to its own stated plan.

◆ Prediction

The next release should be 4.1.0 final or a further beta rather than new features, since the branch is frozen — but the entries give no signal on what is holding it.
