What is OpenLand?

Land-change analysis in R that has spent six years defending one download link.

OpenLand computes land use and cover change metrics from raster time series, including the full intensity analysis framework of Aldwaik and Pontius. The method surface has not moved since the 1.0.0 release in 2020; the four releases since are entirely about surviving CRAN checks and the fragility of fetching its example dataset from Zenodo. The most recent one stops examples from leaving downloaded data in the user's persistent cache directory.

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.

Land-change analysis in R that has spent six years defending one download link.

◆ Current state

OpenLand computes land use and cover change metrics from raster time series, including the full intensity analysis framework of Aldwaik and Pontius. The method surface has not moved since the 1.0.0 release in 2020; the four releases since are entirely about surviving CRAN checks and the fragility of fetching its example dataset from Zenodo. The most recent one stops examples from leaving downloaded data in the user's persistent cache directory.

◆ Where it's heading

Two forces shape every release here: an external data dependency the package cannot control, and upstream churn in the tidyverse. The Zenodo-hosted SaoLourencoBasin dataset has now been the subject of three separate releases — failing gracefully when unreachable, loading through a helper with informative errors, and finally writing to temporary files instead of the cache. The other recurring cost is dplyr, most recently the removal of dplyr::changes() forcing a global-variable declaration. Actual analytical work is rare: the one substantive fix in the window was a memory allocation failure in contingencyTable() on rasters spanning many years or large areas.

◆ Prediction

The entries give no sign of new metrics or methods in progress, so the next release will most likely be another compatibility or CRAN-check response rather than a feature.

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.
