A single-cell data store commits to Zarr v3 and range-readable hosting across four language surfaces
A side-by-side editorial comparison of cTMed and scTypeEval — release velocity, themes, recent moves, and the top alternatives to consider.
Continuous-time mediation effects get standardized centrality, six years into steady patch work
cTMed computes direct, indirect and total effects for continuous-time mediation models, with delta-method, Monte Carlo and bootstrap variants of each. Development is a long run of patch releases from the jeksterslab account, roughly every two months, each adding a function or two. The latest adds standardized centrality measures and allows a diagonal sigma across ten standardized estimators.
scTypeEval judges single-cell annotations without needing a ground truth to judge them against.
scTypeEval evaluates the consistency of single-cell cell type annotations without a ground-truth reference, using pseudobulk distances, Wasserstein distances and reciprocal classification as alternative dissimilarity strategies. It cleared Bioconductor's submission process on its first cycle, moving from a 0.99.30 pre-release in April 2026 to version 1.0.0 in the Bioconductor 3.23 release a month later. It accepts matrix, Seurat and SingleCellExperiment inputs.

The package is filling out a matrix rather than changing shape: for each effect type there is a delta-method, a Monte Carlo and a bootstrap path, and each release closes another cell. The 2025 releases were largely externally forced — an Armadillo 15.0.x transition at CRAN, a citation addition after the Psychological Methods paper landed — which suggests the statistical core has been settled since the 1.0.6 standardization revision.
The diagonal-sigma option has now reached the standardized estimators; extending it to the remaining unstandardized variants is the obvious next cell to fill.

It accepts matrix, Seurat and SingleCellExperiment inputs.
The visible history is short and shaped entirely by the Bioconductor pipeline — the 0.99.x series is that project's submission convention, and 1.0.0 is what acceptance looks like rather than a maturity claim by the authors. What the pre-release notes emphasise is breadth of input format and of dissimilarity strategy rather than a single recommended method, which suggests the package is positioned as a comparison harness rather than a scoring tool. Nothing in these two entries indicates work beyond getting accepted.
With only a submission cycle in the record, there is not enough here to predict a direction; the next release will most likely be whatever the Bioconductor 3.24 cycle requires, and the first post-acceptance release is what will show whether development continues.
