glyrepr
The type system the rest of the glycan stack is built on, being hardened one breaking change at a time.
A side-by-side editorial comparison of glydraw and glymotif — release velocity, themes, recent moves, and the top alternatives to consider.
SNFG glycan cartoons stopped being pictures and became ggplot2 geoms, guides and axis labels.
glydraw renders glycan structures as SNFG-standard cartoons, standalone or exported in bulk, and since 0.7.0 as native ggplot2 components: geom_glycan() for observations, geom_node_glycan() for ggraph networks, guide_glycan() for legends, and scale_x_glycan() and scale_y_glycan() for discrete axes. Appearance is configured through a single reusable style object rather than scattered arguments, a consolidation that 0.8.0 made breaking. The colour handling now expects a complete SNFG palette rather than sparse per-monosaccharide overrides.
A glycan motif matcher trading convenience wrappers for speed, strictness and explicit specs.
glymotif detects and counts structural motifs in glycans, over a built-in motif database or user-supplied structures, with fuzzy modification matching and alignment control. Database motifs are now requested through a db_motifs_spec object carrying their own matching parameters rather than as a name vector with loose arguments, and db_motif_info() exposes the built-in set as an inspectable tibble. A lenient mode lets lower-information glycans match more specific motifs while concrete mismatches still fail, and low-level entry points work directly on igraph objects for other package authors.

The first half of this record is geometry correctness, fixing branch spacing, overlapping linkage annotations, core fucose collisions, triangle alignment and nested side-chain layout, because a cartoon that draws the wrong topology is worse than no cartoon. Once the drawing was trustworthy the package moved outward into ggplot2 and then inward again to consolidate its own API, dropping the glyexp dependency, removing positional argument support, and folding rendering options into style_glydraw(). Each of the last several releases has been explicitly breaking, which is a maintainer using a pre-1.0 window deliberately.
With the style object established and the ggplot2 surface in place, the remaining explicit arguments, show_linkage and orient, are the visible inconsistency and may follow the others into the style. Sibling packages adopt each change within days, as glyenzy did with the new orientation values, so expect the next breaking change to propagate the same way.

Performance has been a recurring line item across at least four releases, culminating in optimised graph searches and candidate filtering aimed at batch analyses, which points at the real workload being whole experiments rather than single glycans. The API has moved the other way from convenience toward explicitness: the add_motifs_lgl() and add_motifs_int() wrappers are deprecated in favour of composing with dplyr or glyexp verbs, optional arguments must now be named, and loose matching parameters were folded into the spec object. Documentation is being steered toward the cohort's newer container types, so this package is following a coordinated migration rather than setting its own course.
With the deprecated annotation wrappers on their way out and documentation already pointing at the replacement verbs, their removal is the likely next breaking change. The lenient matching mode is new enough that its boundary against concrete mismatches will probably need tuning as users apply it to real, partially resolved data.
