Single-cell batch correction that learned to use cell labels, then spent three releases chasing Seurat.
A side-by-side editorial comparison of eulerr and miscmetabar — release velocity, themes, recent moves, and the top alternatives to consider.
The area-proportional Euler diagram package is finished software, and maintained like it.
eulerr generates area-proportional Euler and Venn diagrams by numerically optimizing shape positions and sizes to match set relationships, with the fitting done in C++. The last feature release was 7.0.0 in December 2022, which made the optimization's loss function user-selectable. Everything since has been maintenance: documentation URL corrections, a strip-layout fix when grouping, an Armadillo deprecation, and an R CMD check warning about an unignored config file.
A phyloseq toolbox keeps absorbing metabarcoding methods, and has started splitting into a family.
MiscMetabar extends the phyloseq ecosystem for metabarcoding analysis — taxonomic assignment, diversity curves, filtering and plotting for amplicon sequencing data. Recent substantive releases added IDTAXA-based assignment via DECIPHER, UMAP dimensionality reduction, Hill diversity accumulation curves and kmer complexity plots. The most recent release is a CRAN submission bundling several development merges, including a fix for ggplot2 v4.0.0 breaking the upset plot.

This is a mature package whose problem is solved, and the release pattern reflects that — three of the last four releases changed nothing a user would see. What activity remains is tracking its dependencies rather than its own roadmap: keeping up with Armadillo's deprecations and R CMD check policy is the whole of recent work. The two September 2025 releases an hour apart are a fix and its follow-up, not a development cycle restarting.
The pattern points to continued upkeep triggered by upstream C++ and CRAN check changes rather than new capability. If anything does move, the configurable loss function added in 7.0.0 is the surface with room left in it.

The package grows by adopting established methods from elsewhere in the bioinformatics stack rather than inventing its own, wrapping them for phyloseq objects. The 0.11.0 notes floated a pq-verse — splitting functionality into companion packages such as comparpq for comparing phyloseq objects with different taxonomies, explicitly to make maintenance easier. Several releases in this window carry no notes beyond a merge commit, so the feed understates the work behind them.
The pq-verse split was described as an intention rather than delivered here, so companion packages appearing alongside a slimmer core is the most likely next structural move. Continued ggplot2 v4 compatibility work is the near-term certainty.
