glyfun
glyfun is three releases old and has spent all of them chasing glyexp's container change.
A side-by-side editorial comparison of glyrepr and malariasimulation — release velocity, themes, recent moves, and the top alternatives to consider.
The type system the rest of the glycan stack is built on, being hardened one breaking change at a time.
glyrepr defines the vector types for glycan structures and compositions that every sibling package operates on, with names, NA values, resolution levels from basic through intact, and mapping helpers over structure vectors. Structures now convert to and from node and edge tibbles, low-level constructors support name-preserving construction from trusted graphs, and as_glycan_structure() can degrade element-local failures to NA with one aggregated warning instead of failing the whole vector. The monosaccharide table has been normalised so every entry has a generic form, and substituent support keeps widening.
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.

This package sets the pace for the cohort, and its breaking changes show up as compatibility patches in glyanno, glyenzy and glymotif within days. The direction is toward behaving like a well-built vctrs type: 0.10.0 rewrote the internals to support names and NA properly, 0.11.0 made structure level a vector-wide scalar rather than a per-element value, and the recent releases keep making failure explicit rather than silent, with strict input checks and typed errors replacing quiet drops. Dependencies get shed as readily as features get added, with the parallel-mapping arguments and their furrr and future dependencies removed outright in 0.13.0.
The graph-table conversions added in 0.13.0 and the name-preserving low-level constructors in 0.14.0 both look like foundations for other packages to build structures programmatically, so expect that surface to firm up next. Given the cadence of breaking changes, a 1.0 that freezes the type semantics is the more consequential thing to watch for.

The record here is thin, two entries spanning sixteen months, so the visible cadence understates the work in the underlying repository.
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.
