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.

What is Grype?

Grype has stopped competing on coverage and started competing on how few false positives it prints.

Nearly every release in this window is about match precision rather than new scanning surface. The Go ecosystem gets the most attention — deduplicating the same CVE reported under both a govulndb GO-* ID and its GHSA alias, disabling stdlib CPE matching by default, emitting only stdlib records where appropriate, and respecting withdrawn OSV records. The RHEL side gets parallel work on version streams, RHSA-to-minor-version mapping, and fix dates, with Ubuntu ESM and Chainguard added as data sources.

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.

Grype has stopped competing on coverage and started competing on how few false positives it prints.

◆ Current state

Nearly every release in this window is about match precision rather than new scanning surface. The Go ecosystem gets the most attention — deduplicating the same CVE reported under both a govulndb GO-* ID and its GHSA alias, disabling stdlib CPE matching by default, emitting only stdlib records where appropriate, and respecting withdrawn OSV records. The RHEL side gets parallel work on version streams, RHSA-to-minor-version mapping, and fix dates, with Ubuntu ESM and Chainguard added as data sources.

◆ Where it's heading

The product is being tuned for teams that already run it in CI and are drowning in output — the unit of progress is a suppressed bad match, not a newly detected one. Reachability analysis is the sharpest expression of that: it moves the question from 'is this version vulnerable' to 'does this code path exist in your binary.' Expect vulnerability data quality and distro-specific correctness to keep consuming most of the release notes.

◆ Prediction

Reachability analysis should widen beyond Go if the false-positive reduction holds, and the pattern of onboarding one new ecosystem or distro data source per minor release looks set to continue.
