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 ore?

A stable Oniguruma binding for R that ships correctness fixes and little else.

ore wraps the Oniguruma regex engine for R, and its recent history is entirely about making that binding safe rather than richer. The last three releases fix an infinite-loop hazard on zero-length matches, a named-group propagation bug, and locale detection at startup. The user-facing API has not moved since 1.7.1, when ore_file() began recording whether a file was read as binary.

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.

A stable Oniguruma binding for R that ships correctness fixes and little else.

◆ Current state

ore wraps the Oniguruma regex engine for R, and its recent history is entirely about making that binding safe rather than richer. The last three releases fix an infinite-loop hazard on zero-length matches, a named-group propagation bug, and locale detection at startup. The user-facing API has not moved since 1.7.1, when ore_file() began recording whether a file was read as binary.

◆ Where it's heading

This is a package in maintenance, not development. The changes cluster around C-level hygiene — memory leaks, buffer overruns, sprintf() removal, compiler warnings — which reads as keeping CRAN checks green rather than pursuing new capability. Releases arrive in pairs separated by minutes or in gaps of two years, a cadence typical of a package touched only when something breaks or a CRAN policy shifts.

◆ Prediction

The next release is most likely another correctness or toolchain fix rather than new regex functionality; the README's note about CRAN and mainline diverging suggests the two versions may be reconciled at some point, though the entries do not say when.
