The recursive-computation engine under massProps grows the accessors its consumer needed
A side-by-side editorial comparison of neonUtilities and prospectr — release velocity, themes, recent moves, and the top alternatives to consider.
Two major versions shipped in a year, and this feed will not say what changed in either.
neonUtilities is the R toolkit NEON publishes for pulling and assembling its own observatory data — downloading data products through the NEON API, unzipping and stacking monthly packages into analysis-ready tables, and handling the awkward cases like eddy-covariance and airborne data. It reached 4.0.0 in June and 4.0.1 in July. What those releases contain is not recoverable from this feed: every recent entry is a one-line pointer saying the tag corresponds to a CRAN version, with the change log left in NEWS.md.
prospectr spent its biggest release in years fixing spectra it had been quietly mangling.
prospectr provides the signal-processing layer for near-infrared and visible spectroscopy in R — Savitzky-Golay and gap-segment derivatives, standard normal variate, detrending, continuum removal, splice correction, plus calibration sampling algorithms like Kennard-Stone and DUPLEX and readers for ASD and BUCHI NIRCal instrument files. The May release is the substantial one: a long list of corrections to functions that were returning wrong or missing values rather than failing.

Release cadence has picked up sharply — 3.0.0 through 4.0.1 in under a year, against multi-year gaps before that — and two major-version bumps in that window normally imply breaking changes for anyone pinning the package in a reproducible workflow. Direction cannot be read from the entries themselves. The one substantive note in the feed is older and instructive about how this repository is used: a 2023 development tag that modified stackEddy() to avoid NEON API calls for internal processing pipelines, explicitly not for public use and never submitted to CRAN.
No prediction is supportable from these entries — they contain no description of any change. What can be said is that the 3.x-to-4.x jump and the tight 4.0.0-to-4.0.1 turnaround fit the usual shape of a major release followed by a fix, and anyone depending on the package should read NEWS.md rather than this feed.

The recent work is corrective rather than additive, and several items changed results silently before being caught. continuumRemoval() derived its convex-hull boundary offset from a fixed one-wavelength assumption that broke for fine-resolution spectra or non-nanometre units; cochranTest() passed an invalid argument name to prcomp() and produced incorrect principal component scores; readASD() silently dropped spectra in one branch of its text path. Two file readers were leaking connections. Alongside that runs a smaller thread of decoupling preprocessing steps from each other, most visibly detrend() gaining an snv argument so polynomial detrending can run without the SNV transform that Barnes et al. bundled with it.
The detrend() decoupling is the only recent addition and it fits a broader pipeline-composition direction, so similar separation of other bundled preprocessing steps is the plausible next move. The misspelled substraction argument now carries a deprecation warning, which schedules its removal for a future release.
