cIRT
A choice-based IRT model published once in 2019 and kept compiling ever since
A side-by-side editorial comparison of BORG and momentuHMM — release velocity, themes, recent moves, and the top alternatives to consider.
A cross-validation guard that refuses to run random CV on dependent data unless you insist
BORG detects spatial, temporal and clustered dependence in a modelling dataset and generates a cross-validation scheme that respects it — spatial blocks, temporal blocks, group folds — rather than letting random splits leak information between train and test. Its distinguishing choice is enforcement: when it finds dependence, random CV is blocked outright and needs an explicit allow_random=TRUE to proceed. The package also wraps the standard rsample and caret entry points so the guard applies inside existing workflows.
The animal-movement HMM workhorse, feature-frozen since 2021 and coasting on compiler patches
momentuHMM fits hidden Markov models to animal telemetry — multiple data streams, measurement error, temporally irregular tracks, hierarchical and mixture structures. It is one of the reference implementations in movement ecology and is cited as such. Its capability set has been essentially fixed since 2021; the last four years of releases are compiler, dependency and CRAN metadata work.

The entire visible history is a single day, and the sequence within it is coherent rather than churn: enforcement first, then the evidence layer, then framework integration, then idiomatic R polish. The evidence work matters to the pitch — borg_compare_cv() runs random against blocked CV so users see the inflation on their own data instead of taking the warning on faith, and the methods-text and certificate exports are aimed squarely at getting this into published papers. By the final release the interface has been rebuilt on standard S3 plot and summary methods.
The wrappers so far cover rsample and caret; tidymodels and mlr3 are the obvious remaining entry points if the guard is to reach the workflows it hasn't yet intercepted.

The development arc peaked with 1.5.0 in 2019, which brought hierarchical HMMs, discrete individual random effects and multivariate normal data streams, and effectively closed with 1.5.4 in 2021. What follows is a maintenance tail driven entirely by other people's changes: RcppArmadillo deprecating a function, Brobdingnag unexporting one, crawl dropping an import, CRAN asking for metadata edits. The package is stable in the sense that matters to its users and dormant in the sense that matters to its roadmap.
On this pattern the next release will be another upstream-forced patch rather than new modelling capability, unless a maintainer change or a new methods paper reopens development.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — r-package — within Analytics. BORG and momentuHMM are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. BORG and momentuHMM are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
