What is Infisical?

Infisical is shipping weekly, with batched secret edits and an agent credential vault as the real threads.

Infisical tags a release every few days. Most of the volume is UI cleanup, but two features run through it: batched secret and folder changes in the Secrets Overview, now always on, and Agent Vault, which manages credentials and proxies for AI agents. Code signing gained support for existing DigiCert certificates held in an HSM.

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.

5.0

Infisical is shipping weekly, with batched secret edits and an agent credential vault as the real threads.

◆ Current state

Infisical tags a release every few days. Most of the volume is UI cleanup, but two features run through it: batched secret and folder changes in the Secrets Overview, now always on, and Agent Vault, which manages credentials and proxies for AI agents. Code signing gained support for existing DigiCert certificates held in an HSM.

◆ Where it's heading

The product is widening from a secrets store into a broader machine-identity platform: certificates, code signing, secret scanning and credentials handed to AI agents. Frontend work is consolidating the UI and removing legacy dependencies.

◆ Prediction

Agent Vault looks like the next feature to graduate; expect more releases around agent credential handling and proxy tokens.

0.0

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.
