APCalign vs OpenCTI: at a glance
What is APCalign?
APCalign spent this year fixing the counts it had been quietly getting wrong
APCalign standardises Australian plant names against the APC and APNI taxonomic resources and derives state-level native/introduced status from them. The feed is GitHub releases tagged by resource download date rather than semantic version, so titles carry no information about content. The two 2026 releases are the only substantive ones in the window: infrataxa support in the diversity functions, then a fix for a grep that had been matching the wrong columns.
What is OpenCTI?
OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
The mainline is working through the consequences of the connector catalog redesign, with each release closing gaps around it: filters and saved searches became shareable, dashboards can reuse them, and background tasks can now edit relationship start and stop times in bulk. Alongside that, an LTS branch is being maintained in parallel — 7.260309.0-lts.7 backports the security fixes and dependency updates from the recent mainline releases without any of the feature work.

◆ Current state
APCalign standardises Australian plant names against the APC and APNI taxonomic resources and derives state-level native/introduced status from them. The feed is GitHub releases tagged by resource download date rather than semantic version, so titles carry no information about content. The two 2026 releases are the only substantive ones in the window: infrataxa support in the diversity functions, then a fix for a grep that had been matching the wrong columns.
◆ Where it's heading
Development is driven by users reporting that outputs do not match what they expect, and the fixes keep landing in the same two functions — create_species_state_origin_matrix() and native_anywhere_in_australia(). The infrataxa parameter and the reordered output columns came from user requests; the guard-ordering and grep fixes came from a filed issue. What is emerging is that the origin-matrix logic was written loosely and is now being tightened case by case, with tests and state diversity benchmarks added alongside.
◆ Prediction
Both recent releases touched the same pair of functions and the fixes were found by inspection rather than by tests failing, so more corrections in the native-status path are the likely next content — the benchmarks added in March are the mechanism that would surface them.

OpenCTI is rebuilding its connector layer into a marketplace and wiring the platform to XTM Hub
◆ Current state
The mainline is working through the consequences of the connector catalog redesign, with each release closing gaps around it: filters and saved searches became shareable, dashboards can reuse them, and background tasks can now edit relationship start and stop times in bulk. Alongside that, an LTS branch is being maintained in parallel — 7.260309.0-lts.7 backports the security fixes and dependency updates from the recent mainline releases without any of the feature work.
◆ Where it's heading
Two things are running at once. The product arc is about making the platform's own surfaces composable — a faceted connector marketplace, reusable filters, workflow approval and draft metadata — rather than adding threat-intel primitives. The engineering arc is a maintained LTS channel that gets security parity and nothing else, which is how a project behaves once it has deployments it cannot ask to track weekly releases.
◆ Prediction
Expect the mainline to keep landing XTM Hub integration and workflow-governance work at roughly a weekly cadence, with a matching lts.8 backport following whenever the next batch of security fixes accumulates.
