ggInterval vs Transmission: at a glance
What is ggInterval?
Interval-valued data plotting, spending 2026 making its function names and examples survive CRAN.
ggInterval visualizes symbolic interval-valued data — observations recorded as ranges rather than points — with a family of plot functions in the ggplot2 idiom. The plot catalogue grew most recently with interval correlation heatmaps and interval line plots compatible with time-series input. The three releases before that were corrections: seven plot functions renamed for consistency, examples switched from dontrun to donttest at CRAN's request, and a vignette rewritten to demonstrate every function in one place.
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.

Interval-valued data plotting, spending 2026 making its function names and examples survive CRAN.
◆ Current state
ggInterval visualizes symbolic interval-valued data — observations recorded as ranges rather than points — with a family of plot functions in the ggplot2 idiom. The plot catalogue grew most recently with interval correlation heatmaps and interval line plots compatible with time-series input. The three releases before that were corrections: seven plot functions renamed for consistency, examples switched from dontrun to donttest at CRAN's request, and a vignette rewritten to demonstrate every function in one place.
◆ Where it's heading
The package is consolidating an interface that had drifted. Renaming seven functions in a single release is the clearest signal — the naming was inconsistent enough to be worth breaking, and the vignette rewrite that followed suggests discoverability was the underlying complaint. Underneath that, the additions are steady and narrow: each release brings interval-aware versions of plot types that already exist for point data, which is the whole premise of the package.
◆ Prediction
The pattern of porting one more standard plot type into interval-aware form each release is the most likely continuation; the tsplot compatibility in the latest version hints that time-series interval data is the direction attracting attention.
Transmission
0.0INFRA · APIS
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.
