glymotif
A glycan motif matcher trading convenience wrappers for speed, strictness and explicit specs.
A side-by-side editorial comparison of ibdsim2 and malariasimulation — release velocity, themes, recent moves, and the top alternatives to consider.
A pedigree IBD simulator that absorbed its own web app and now optimises for dense marker panels.
ibdsim2 simulates identity-by-descent sharing along chromosomes for arbitrary pedigrees, in both autosomal and X-chromosomal form, with downstream tools for segment statistics, pattern finding and distribution plots. Since 2.1.0 the Shiny front end lives inside the package and launches via launchApp() rather than sitting in a separate repository. The latest release is performance work, with profileSimIBD() substantially sped up for dense marker panels and ibdsim() skipping recombination in pedigree branches that cannot affect the result.
An individual-based malaria model that grew a second parasite species, then froze itself for reproducibility.
malariasimulation is an individual-based transmission model whose 2.0 line added a full Plasmodium vivax implementation alongside the existing P. falciparum one, including hypnozoites, competing hazards, vivax-specific drug handling, an equilibrium solution and dedicated outputs. The most recent entry is not a code release at all but a coordinated malariaverse_01_2025 tag applied across the package suite, freezing every package at a matching version so existing analyses can be reproduced after the suite moves on. The record here is thin, two entries spanning sixteen months, so the visible cadence understates the work in the underlying repository.

Two long-running threads. One is the app as a first-class part of the package, which has been getting input validation, dependency checks and plotting fixes release after release, treating a research GUI as software to be maintained rather than a demo. The other is numerical care: the built-in recombination map was rebuilt in 2.3.0 with better chromosome endpoints and a thinning algorithm that cut it from about 38,000 points to 14,000 without losing accuracy, and IBD segment merging has been made consistent across the realised-coefficient functions. The maintainer flags repeatedly that seeded results may differ across versions, which is the right disclosure for a simulator used in published analyses.
The recent work points at further speed on dense panels and continued hardening of app input handling, both of which have appeared in each of the last several releases. Nothing here signals a new modelling capability on the way.

The direction visible in these entries is toward being a suite rather than a package. The snapshot tag is explicit that packages are installed together at one tag rather than mixed with main, which is the versioning discipline of a research platform whose users publish against specific model versions. On the modelling side, the vivax work was not a parameter addition but a distinct biology, with immunity structures removed rather than reused, indicating the model now carries two species with genuinely different natural histories.
The snapshot describes itself as freezing state immediately before an upcoming update, so the next visible release should be that update across the suite rather than any single package. Whether it extends the vivax model or the falciparum one is not indicated here.
