PurpleAir
The R client for PurpleAir sensors keeps finding its time-averaging was wrong.
A side-by-side editorial comparison of discretefdr and scimesh — release velocity, themes, recent moves, and the top alternatives to consider.
The discrete-data FDR package is being pared into one piece of a larger multiple-testing suite.
DiscreteFDR implements false discovery rate procedures adapted for discrete test statistics, where the standard continuous-case corrections are conservative. It now covers a discrete Benjamini-Yekutieli procedure alongside the Benjamini-Hochberg variants it started with, including adaptive versions. Its datasets and test-result classes have been moved out into companion packages, so it increasingly does one job and defers the rest.
A C++ mesh renderer grinding through CRAN's gate, one policy fix at a time
scimesh is a C++ scientific mesh rendering library with an R binding, released in tight bursts by the dfsp-spirit neuroimaging group. The last month is dominated by CRAN admission work: stripped debug symbols, assert removal in vendored third-party code, vignette index fixes. Around that compliance grind sit genuine additions — an rgl-to-scimesh auto-conversion path, a camera_orbit helper for video, contrast as a render option.

The direction is decomposition into a suite. The amnesia dataset went to DiscreteDatasets, summary output now interoperates with the DiscreteTestResults class from DiscreteTests, and match.pvals() stopped being exported — each release trims something that belongs elsewhere. What remains gets methodological additions at a slow, deliberate cadence, with performance work on the step-up procedures that dominate cost when the number of tests is large. Recent activity is maintenance: replacing deprecated calls the package still made of its own siblings. This is a mature statistical package whose release notes are short because the methods underneath them are settled.
Expect further alignment with the companion packages rather than new procedures, since the last substantive release was already about interoperating with DiscreteTests classes and the most recent one about clearing deprecations.

The tag stream is non-monotonic — 0.2.5, 0.2.3 and 0.2.6 land within 40 seconds of each other, and 0.2.8 precedes nothing — so version order here says nothing about what shipped when. Read as a whole, the arc is a C++ codebase being domesticated for R distribution: the rendering features are largely settled, and the effort has moved to making an >5MB-adjacent C++ package survive R CMD check --as-cran. The R vignette has been restructured twice in three weeks.
Expect continued CRAN-review round-trips at 0.3.x until acceptance, with feature work confined to the CLI renderer examples rather than the core library.
