A side-by-side editorial comparison of glycoverse and ibdsim2 — release velocity, themes, recent moves, and the top alternatives to consider.
glycoverse is a meta-package whose whole job is keeping a dozen siblings installable.
glycoverse installs and version-checks the rest of the stack via glycoverse_update(), glycoverse_deps(), and glycoverse_sitrep(). Its releases track membership and distribution rather than capability: glyfun was reclassified as non-core in 0.3.1, the case studies were moved out to a standalone tutorials site in 0.3.2, and 0.2.5 switched installation from GitHub releases to r-universe. No analysis code lives here.
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.

The package is thinning as the ecosystem grows. Documentation moved off to its own site, packages keep shifting between core and non-core, and installation was handed to pak and r-universe rather than bespoke logic. Meanwhile the substantive work in this window happened in the siblings, notably the container migration that reshaped ten of them without requiring a glycoverse release at all.
Expect the next release to be another membership or version-pinning adjustment, most likely acknowledging the newer packages that joined during the container migration.

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.
