An MLE package rebuilt around composable solvers, then renamed to match.
A side-by-side editorial comparison of mritc and patRoon — release velocity, themes, recent moves, and the top alternatives to consider.
A dormant MRI tissue-classification package revived under a new maintainer.
mritc performs MRI tissue classification in R using Gaussian mixture and hidden Markov models. After a long dormancy it changed hands to a new maintainer, and the three releases in this window all land within weeks of each other — two of them seconds apart, a backfill of the handover release alongside the first substantive one. The work so far is modernisation rather than new methodology.
patRoon 3.0.0 adds ion mobility, opening a dimension its workflows never had.
patRoon is an R workflow platform for non-target mass spectrometry screening, orchestrating feature detection, grouping, annotation and identification across many external tools. Version 3.0.0 is a major release adding support for ion mobility separation, new feature detection and grouping algorithms, revised identification confidence estimation, and use of sample metadata. The preceding five releases were maintenance, with the last comparable step being MS2Tox and MS2Quant integration in 2.3.0.

The clear direction is reducing what the package demands of the systems it installs on: heavyweight visualisation dependencies moved to optional, tkrplot dropped entirely, and the default plotting backend switched to a package already present in the dependency tree. A test suite and coverage tooling arrived where there had been none. The remaining releases are CRAN-check fallout from that restructuring, which is the expected shape of a revival.
Expect further consolidation under the new maintainer — CRAN check fixes and test coverage — before any change to the classification methods themselves.

The pattern is long maintenance stretches punctuated by releases that add a whole capability: toxicity and concentration prediction at 2.3.0, then ion mobility at 3.0.0. Feed entries are short pointers to the NEWS file rather than full changelogs, so the fine detail of each release sits outside this feed, but the headline claims are specific enough to read direction from. The upgrade notes flagged in the 3.0.0 summary indicate this one is not a drop-in replacement.
Expect the next releases to be maintenance work stabilising the ion mobility path, following the same rhythm that followed 2.3.0.
