Single-cell batch correction that learned to use cell labels, then spent three releases chasing Seurat.
A side-by-side editorial comparison of scimesh and simmer.plot — release velocity, themes, recent moves, and the top alternatives to consider.
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 plotting companion to simmer, shipping only when the simulator or a graphics dependency moves.
simmer.plot renders discrete-event simulation output — S3 plot() methods over get_mon_arrivals(), get_mon_attributes() and get_mon_resources(), plus trajectory diagrams drawn through DiagrammeR. Since 0.1.12 the methods attach to the monitoring data itself rather than the simulation environment, and 0.1.18 finished that migration by deleting the deprecated environment-level methods.

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.

This package moves when something it depends on moves. Its history is a sequence of parser fixes for new simmer trajectory formats, DiagrammeR and tidyr and dplyr version bumps, and ggplot2 workarounds. The one clear internal decision — plotting monitor output instead of the environment — was made in 2017 and completed six years later. The 2025 release fixes documentation cross-references and nothing else.
The next release most likely follows a simmer trajectory-format change or a CRAN documentation policy, matching every recent entry. There is no visible feature work in the pipeline.
