A side-by-side editorial comparison of forrel and malariasimulation — release velocity, themes, recent moves, and the top alternatives to consider.
forrel is getting faster at the simulations forensic kinship work actually spends its time on.
forrel handles forensic pedigree analysis: kinship likelihood ratios, profile simulation, relationship checking, and missing person calculations. Version 1.9.0 synced with pedtools 2.11.0's loop handling, which the release notes credit with enabling complex pedigrees that were previously intractable, and moved profileSim() to mirai for parallelism. It also added fEstimate() for inbreeding coefficients and parentChildLikelihood() as a fast path for the simplest case.
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 threads run through the window. One is making the common operations cheap: faster simulations through reorganized likelihood calculations, a dedicated parent-child path, dropped map attribute preservation, log-likelihoods to avoid underflow in kinshipLR(). The other is making relationship checking presentable, with checkPairwise() growing ggplot2 and plotly output, verbal relationship descriptions, and bootstrap p-values. Reference data is maintained alongside both, with the FORCE SNP panel completed and an X-chromosomal counterpart added.
With profileSim() on mirai and the loop handling synced, the next likely step is extending mirai parallelism to the other simulation-heavy functions such as exclusionPower() and the bootstrap in checkPairwise().

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.
