fracture vs ibis.iSDM: at a glance
What is fracture?
fracture solved decimal-to-fraction conversion years ago and now only answers to CRAN.
A single-purpose package converting decimals to fractions, with a matrix form and a Unicode pretty-printer. The functional work finished in 2021-2022: an explicit denom argument, named-argument-only calling, sensible denominators at 0 and 1, and NA and Inf handled rather than erroring. The only release since is a four-year-later removal of a C++11 system requirement that R's C++17 default made redundant.
What is ibis.iSDM?
A raster-to-terra migration is the only readable change in a feed of merge notes.
ibis.iSDM fits integrated species distribution models in R. Its release notes are GitHub's auto-generated pull-request lists, so most tags say only which branch was merged and by whom. The one release with a written note, 0.0.5, records the migration from raster to terra across the whole package, with an explicit warning that established code may break.

◆ Current state
A single-purpose package converting decimals to fractions, with a matrix form and a Unicode pretty-printer. The functional work finished in 2021-2022: an explicit denom argument, named-argument-only calling, sensible denominators at 0 and 1, and NA and Inf handled rather than erroring. The only release since is a four-year-later removal of a C++11 system requirement that R's C++17 default made redundant.
◆ Where it's heading
This is a completed utility. Its arc ran from correctness — floating-point rounding, exhaustive tests across millions of fractions — through API tightening, to edge-case tolerance, and then stopped. The 2026 release contains no user-visible change at all; it exists because CRAN's toolchain moved, which is the characteristic maintenance mode of a small package that does one thing correctly.
◆ Prediction
Nothing in these entries suggests new functionality; expect further releases only when R or CRAN policy forces one, as this one did.

A raster-to-terra migration is the only readable change in a feed of merge notes.
◆ Current state
ibis.iSDM fits integrated species distribution models in R. Its release notes are GitHub's auto-generated pull-request lists, so most tags say only which branch was merged and by whom. The one release with a written note, 0.0.5, records the migration from raster to terra across the whole package, with an explicit warning that established code may break.
◆ Where it's heading
Direction cannot be read from this feed with any confidence - three of the four visible tags carry nothing beyond merge titles and a full-changelog link. What is visible is a 2023 spent on dependency modernisation and dev-branch merges, ending with a 0.1.1 tag that December and nothing since.
◆ Prediction
These entries do not support a prediction; the notes would have to carry written content before a direction could be read from them.
