glymotif
A glycan motif matcher trading convenience wrappers for speed, strictness and explicit specs.
A side-by-side editorial comparison of glyenzy and vellumverse — release velocity, themes, recent moves, and the top alternatives to consider.
Glycan biosynthesis as a traceable enzyme graph, now including sulfation and gaps it can bridge.
glyenzy infers which enzymes could have produced a glycan and traces biosynthetic routes to it, backed by curated per-enzyme rules for human glycosyltransferases and, since 0.7.0, twelve sulfotransferases. Biosynthesis functions return typed network objects that keep their igraph interface while supporting layered DAG plots with glycan nodes and labelled enzyme edges. Where no concrete enzyme covers a step, bounded virtual transitions bridge the gap and are marked so users can see which edges are inferred rather than enzymatic.
A meta-package whose entire changelog is a version pin, tracking an ecosystem moving faster than it is.
vellumverse attaches the vellum graphics ecosystem in one library() call, reports which versions loaded, lists the bundled packages and surfaces functions masked across them. It is deliberately dependency-light, having dropped rlang and declared only what the conflict reporter actually uses. Since 0.2.0 every release has been a version pin bump rather than new behaviour of its own.

Two kinds of release alternate here. One is enzyme curation, a steady stream of rule corrections for the FUT, MAN1A and MGAT families and removals where an enzyme turned out to act only on glycolipids, which is the unglamorous accuracy work a rule-based inference engine lives on. The other is turning biosynthesis output into a first-class object: paths became networks, networks became typed with plotting support, and targets became a marked vertex attribute. The package moves in lockstep with its siblings, pinning glyrepr 0.13.0 and glymotif 0.17.0 as those refreshed their data and matching APIs, and the latest release already speaks glydraw 0.8.0's orientation values.
The paucimannose N-glycan support dropped in 0.7.0 is the obvious loose end, with users told to stay on 0.6.3, so a reinstated implementation is a plausible next move. Beyond that the virtual-step machinery is new enough that its heuristics, particularly the inferred step limits added in 0.8.1, should keep being tuned.

The release record is an index of other packages' work: four of the last six entries do nothing but raise the floor on vellum, vellumplot and vellumwidget. The cadence tells the real story, with pins moving roughly weekly and each bump chasing a minor release somewhere downstream, so the meta-package is currently a distribution convenience rather than a component. The one genuinely structural release in the window was 0.2.1, which trimmed the dependency surface to keep an attach-only package cheap to install.
Expect the pin bumps to keep pace with the ecosystem's weekly releases rather than any feature of its own, and the pin on vellumplot to move again as the interaction grammar the widget now depends on continues to land. Whether vellumverse ever grows beyond attach-and-report is not visible in these entries.
