What is mlr3filters?

mlr3filters grows one feature-selection filter at a time

mlr3filters provides feature-filter methods to mlr3. Its releases follow a consistent shape: one or two new filters, broader feature-type support on existing ones, and error-message work. Boruta and a univariate Cox filter arrived in 0.8.0; 0.9.0 extended Boruta to logical, factor and ordered features and moved param_set to an active binding.

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.

mlr3filters grows one feature-selection filter at a time

◆ Current state

mlr3filters provides feature-filter methods to mlr3. Its releases follow a consistent shape: one or two new filters, broader feature-type support on existing ones, and error-message work. Boruta and a univariate Cox filter arrived in 0.8.0; 0.9.0 extended Boruta to logical, factor and ordered features and moved param_set to an active binding.

◆ Where it's heading

This is incremental infrastructure that tracks mlr3's own conventions — cli printing, prototype-based dictionaries, featureless learners as defaults — while slowly widening which data types each filter accepts. Nothing in the recent history suggests a change of scope.

◆ Prediction

Expect another filter or two plus continued feature-type broadening, keeping pace with mlr3 core conventions.

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.
