OpenCTI vs spmodel: at a glance
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.
What is spmodel?
Spatial regression in R, adding block kriging and then tuning the numerics underneath it
spmodel fits spatial linear and generalised linear models, for both point-referenced and areal data, with prediction and diagnostics attached. Block prediction arrived in 0.11.0 and the releases since have refined it. The most recent release changes optimiser behaviour: the default Nelder-Mead relative stopping tolerance tightens from 1e-4 to 1e-6 to reduce convergence on local rather than global maxima.

◆ 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.

0.0ANALYTICS
Spatial regression in R, adding block kriging and then tuning the numerics underneath it
◆ Current state
spmodel fits spatial linear and generalised linear models, for both point-referenced and areal data, with prediction and diagnostics attached. Block prediction arrived in 0.11.0 and the releases since have refined it. The most recent release changes optimiser behaviour: the default Nelder-Mead relative stopping tolerance tightens from 1e-4 to 1e-6 to reduce convergence on local rather than global maxima.
◆ Where it's heading
Two threads run in parallel. The first is expanding what can be predicted — point predictions, then areal averages over a region via block kriging, then better accuracy and efficiency for that path as the block size default moved from 1000 to 4000 in 0.12.0. The second is numerical trustworthiness, and it is unusually prominent here: a range-constraint option for stability in 0.9.0, a corrected log determinant of the fixed effects in the restricted log likelihood in 0.11.0, a cloud semivariogram that had been doubling the semivariance fixed in 0.11.1, and now a tighter optimiser tolerance. Several of these silently changed results before they were caught.
◆ Prediction
Expect the maintainers to keep publishing explicit reproduction instructions alongside numerical default changes, as 0.13.0 does by documenting the `control = list(reltol = 1e-4)` escape hatch. The entries give no signal of expansion beyond the current model families.
