The recursive-computation engine under massProps grows the accessors its consumer needed
A side-by-side editorial comparison of ggsketch and PEIMAN2 — release velocity, themes, recent moves, and the top alternatives to consider.
ggsketch stopped being a line style and became a drawing-medium simulator.
ggsketch is a ggplot2 extension that renders plots as if drawn by hand. Through the 1.x line that meant one thing: roughening outlines and fills with configurable jitter. The 2.0.0 release published in July reframes the package around simulated drawing media — pen, chisel-tip highlighter, airbrush — and simulated paper grounds, with the sketch geoms inheriting whichever medium is set.
PEIMAN2 cut its annotation database loose from its release cycle without breaking CRAN.
PEIMAN2 does enrichment analysis over post-translational modifications, testing whether a protein list is enriched for particular PTMs against UniProt-derived annotations, with translation functions bridging to mass spectrometry workflows. Its answers are only as current as its bundled database, and until June that database could only be refreshed by releasing a new package version. Version 1.1.0 changes that.

The maintainer states 2.0.0 is the engine for a series, and the release notes read that way: the medium sampler and the paper renderer are new Layer-1/Layer-2 primitives that every existing geom picks up for free. The second thread is correctness under real plot layouts — corner-aware label repulsion, boundary densification so bars bend under polar coordinates, reserved panel room so edge labels stop clipping. Geom coverage keeps widening in parallel, with chicklet charts the newest addition.
Expect the rest of the 2.x series to add media on top of the new sampler rather than more geoms, since that is where 2.0.0 put the extensibility. The default hachure-pitch change already shifts existing output slightly, so a follow-up patch tuning those defaults against real plots is likely.

Its answers are only as current as its bundled database, and until June that database could only be refreshed by releasing a new package version. Version 1.1.0 changes that.
The package has been moving from a fixed snapshot toward versioned, user-selectable data. Earlier releases updated the bundled database in place — 1.0.0 shipped the March 2025 version and said little else — which meant the annotation vintage was whatever the package version implied. Now update_peiman_database() downloads and caches external database files and UniProt PTM lists, enrichment workflows take a database_version argument, and the mass-spec translators take a ptmlist_version, so an analysis can pin a dated database rather than a package release. The CRAN-safe default is preserved deliberately: loading, examples and checks still use the bundled internal data and need no network.
Version pinning is now expressible but the release notes do not describe how a chosen version is recorded in output, so surfacing the active database version in results is the natural companion. The database and the UniProt PTM list are versioned separately, which leaves room for a combined manifest.
