What is glyparse?

glyparse is quietly becoming the universal reader for glycan text notation.

glyparse converts the various text encodings of glycan structures into glyrepr objects. Version 0.7.0 was the widest release in the window, adding parsers for GlyCAM IUPAC, IUPAC-compact, KCF, and LINUCS and teaching auto_parse() to route them, alongside a long list of GlycoCT and WURCS edge cases. The rest of the window is error-handling and performance work: an on_failure switch, a 10-30x speedup on large inputs, and NA and name preservation.

What is StreamCatTools?

StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet

StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.

glyparse is quietly becoming the universal reader for glycan text notation.

◆ Current state

glyparse converts the various text encodings of glycan structures into glyrepr objects. Version 0.7.0 was the widest release in the window, adding parsers for GlyCAM IUPAC, IUPAC-compact, KCF, and LINUCS and teaching auto_parse() to route them, alongside a long list of GlycoCT and WURCS edge cases. The rest of the window is error-handling and performance work: an on_failure switch, a 10-30x speedup on large inputs, and NA and name preservation.

◆ Where it's heading

Two things are being built at once. Coverage keeps widening, both in the number of notations supported and in how much malformed or ambiguous real-world input each parser tolerates: alditol residues, unknown ring positions, ambiguous sialic acid descriptors, uppercase residue IDs. Meanwhile the package is hardening for batch use, with progress bars, vectorized speed, and a choice between erroring and returning NA on unparsable strings.

◆ Prediction

With the major notations now covered, expect further releases to go to robustness on messy inputs and to keeping pace with glyrepr's structure representation rather than adding formats.

StreamCatTools is quietly moving off web services and onto cloud-native GeoParquet

◆ Current state

StreamCatTools is the R client for the US EPA's StreamCat and LakeCat watershed metrics datasets. Through 2025 it worked almost entirely against the StreamCat web API, and much of its release history is about making those HTTP calls survive real conditions — POST bodies for long COMID lists, tryCatch around service outages, tests that skip when the service is down. 0.11.0 in May 2026 introduces a different data path.

◆ Where it's heading

The newest release adds lc_get_watershed(), which returns a lake watershed as an sf feature by reading an S3-hosted, HUC2-partitioned GeoParquet dataset with DuckDB, optional HUC2 filtering, retries and multi-threading. That is a materially different access model from the web service the rest of the package uses. Alongside it, 0.10.0 added National Nutrient Inventory access and nitrogen/phosphorus budget plotting, extending the package past retrieval into presentation.

◆ Prediction

If the GeoParquet path proves faster and more reliable than the web service, migrating more retrieval functions onto it is the obvious next move. The entries do not say whether EPA intends to publish the full metric catalogue in that format.
