What is biocro?

BioCro swapped an unstable iteration for real root finders, changing what its crop models compute.

BioCro is a C++ crop growth simulator with an R interface, built from swappable modules for photosynthesis, respiration and development. Version 3.3.0 added multidimensional and one-dimensional root finders to the C++ source and put them to work immediately, replacing the fixed-point iteration used for intercellular CO2 with a Dekker root finder on the grounds that fixed-point iteration is known to be unstable there. Getting to that release also required moving from C++11 to C++17 and updating the bundled boost from 1.71 to 1.89.

What is rosm?

rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl

rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.

BioCro swapped an unstable iteration for real root finders, changing what its crop models compute.

◆ Current state

BioCro is a C++ crop growth simulator with an R interface, built from swappable modules for photosynthesis, respiration and development. Version 3.3.0 added multidimensional and one-dimensional root finders to the C++ source and put them to work immediately, replacing the fixed-point iteration used for intercellular CO2 with a Dekker root finder on the grounds that fixed-point iteration is known to be unstable there. Getting to that release also required moving from C++11 to C++17 and updating the bundled boost from 1.71 to 1.89.

◆ Where it's heading

Two threads run together: the biology is being broken into finer interchangeable modules — separate maintenance respiration, alternative linear and logistic SLA methods, a direct development-index module — while the numerics underneath are being made solvable in general. The root finders are explicitly staged to move into the shared biocro/framework repository, so this is groundwork for other models rather than for this package alone.

◆ Prediction

More module-level alternatives that depend on simultaneous-equation solutions are the natural follow-on, and the root finders should migrate out to biocro/framework as the notes state.

rosm 0.3.0 silently deprecates its entire API and rebuilds on wk and curl

◆ Current state

rosm downloads and stitches raster map tiles from OpenStreetMap and similar sources for use in R. After six years without a release, 0.3.0 deprecated the whole previous API, dropped the rgdal dependency, and introduced a replacement built on wk geometry and curl's multi-download interface. The follow-up 0.3.1 is documentation and CI work, plus test skips for Bing and Stamen URLs that no longer resolve.

◆ Where it's heading

The package is being brought back from dormancy on modern foundations rather than extended. rgdal's retirement forced the issue, and the maintainer used it to replace the download path with concurrent curl requests and to hand geometry handling to wk. What follows is consolidation: dead built-in tile sources are being tested around rather than replaced, which leaves the source registry as the obvious unfinished edge.

◆ Prediction

The dead Bing and Stamen endpoints are currently skipped rather than fixed, so the next release most likely prunes or re-points the built-in tile source list and continues retiring the silently deprecated functions.
