glyrepr vs OpenCTI: at a glance
What is glyrepr?
The type system the rest of the glycan stack is built on, being hardened one breaking change at a time.
glyrepr defines the vector types for glycan structures and compositions that every sibling package operates on, with names, NA values, resolution levels from basic through intact, and mapping helpers over structure vectors. Structures now convert to and from node and edge tibbles, low-level constructors support name-preserving construction from trusted graphs, and as_glycan_structure() can degrade element-local failures to NA with one aggregated warning instead of failing the whole vector. The monosaccharide table has been normalised so every entry has a generic form, and substituent support keeps widening.
What is OpenCTI?
OpenCTI spends a release unblocking queues and hardening upserts
7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.

◆ Current state
glyrepr defines the vector types for glycan structures and compositions that every sibling package operates on, with names, NA values, resolution levels from basic through intact, and mapping helpers over structure vectors. Structures now convert to and from node and edge tibbles, low-level constructors support name-preserving construction from trusted graphs, and as_glycan_structure() can degrade element-local failures to NA with one aggregated warning instead of failing the whole vector. The monosaccharide table has been normalised so every entry has a generic form, and substituent support keeps widening.
◆ Where it's heading
This package sets the pace for the cohort, and its breaking changes show up as compatibility patches in glyanno, glyenzy and glymotif within days. The direction is toward behaving like a well-built vctrs type: 0.10.0 rewrote the internals to support names and NA properly, 0.11.0 made structure level a vector-wide scalar rather than a per-element value, and the recent releases keep making failure explicit rather than silent, with strict input checks and typed errors replacing quiet drops. Dependencies get shed as readily as features get added, with the parallel-mapping arguments and their furrr and future dependencies removed outright in 0.13.0.
◆ Prediction
The graph-table conversions added in 0.13.0 and the name-preserving low-level constructors in 0.14.0 both look like foundations for other packages to build structures programmatically, so expect that surface to firm up next. Given the cadence of breaking changes, a 1.0 that freezes the type semantics is the more consequential thing to watch for.

OpenCTI spends a release unblocking queues and hardening upserts
◆ Current state
7.260817.0 is a fix release. The most consequential item is malformed STIX messages nacking forever and blocking worker queues indefinitely — a stall in the ingestion path rather than a display bug. Alongside it: upsert clearing an existing createdBy when incoming confidence is higher, draft upserts crashing on existing attack patterns, OTP handling in the stream middleware, and case template relation authorization. Score fields were added to threat actor groups, intrusion sets and malware.
◆ Where it's heading
The platform's feature energy went into the connector catalog and integrations rework in July, and the releases since have been consolidating: mass operations on relation times, shareable saved searches, and now a pass over ingestion robustness. Adding score to more entity types continues the slow enrichment of the data model that runs underneath the feature work.
◆ Prediction
Given score arriving on three entity types in one release, expect it to keep spreading across the data model, and the queue-blocking class of bug to draw more worker-side hardening.
