cIRT
A choice-based IRT model published once in 2019 and kept compiling ever since
A side-by-side editorial comparison of ddpcr and manymome — release velocity, themes, recent moves, and the top alternatives to consider.
A decade-old droplet PCR analysis package woken up for one compatibility release
ddpcr reads droplet digital PCR data exported from Bio-Rad's QuantaSoft, classifies droplets and ships a Shiny interface over the analysis. It has been on CRAN since 2016 alongside an F1000Research paper. The last ten years of releases are almost entirely about keeping pace with QuantaSoft export formats and with churn in its own R dependencies.
Steady quarterly releases behind a feed that shows almost none of what changed.
manymome computes indirect and moderated effects for path-analysis and SEM models using bootstrap and Monte Carlo intervals. The four most recent CRAN releases (0.3.2 through 0.3.6) publish as bare pointers to the package's own NEWS page, so the feed carries no changelog text for any of them. Where content is visible, at 0.3.1 and 0.2.9, the work is fitting-engine breadth and speed rather than new methodology.

This is a maintained-not-developed package, and the release history shows it plainly: a burst of real work through 2016 and 2017, then long silences broken by releases whose stated purpose is staying on CRAN. The 2026 release fits the same shape but does more than the 2023 pair did, adding support for a QuantaSoft variant and finally retiring dplyr code written against a tidy evaluation style that has been outdated for years.
Nothing in the entries points to new analysis capability; the pattern suggests the package surfaces again only when a QuantaSoft export change or a dependency deprecation forces it.

The legible arc runs toward turning the q_* quick-mediation wrappers into a complete workflow: lavaan::sem fitting with full information maximum likelihood for missing data, a plot method, and user-specified mediation models, alongside repeated optimization of do_boot() and do_mc(). Cadence is roughly quarterly and has held for two years. What the last four versions actually contain cannot be read from this feed.
Expect continued quarterly CRAN releases extending the q_* family; beyond that the entries shown do not support a confident call on direction.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — cran — within Analytics. ddpcr and manymome 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. ddpcr and manymome are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
