What is bbotk?

bbotk is generalizing from an optimizer toolkit into an evaluation framework.

bbotk is the black-box optimization backend behind mlr3 tuning: search spaces, terminators, archives, and an async layer built on rush. Recent releases pair steady async-API buildout with removal of the deprecated arguments that preceded it. The 1.9.0 release introduced EvalInstance as a base class for OptimInstance, separating evaluating an objective from optimizing one.

What is Neo4j?

Neo4j moves its full graph algorithm catalog onto the free tier and adds attribute-based access control.

Neo4j is pushing capability downward and outward at the same time. The complete Graph Data Science catalog — 65+ algorithms — now runs on AuraDB Free in isolated, unbilled sessions, while Business Critical and Virtual Dedicated Cloud tiers gain attribute-based access control with time-windowed permissions and IdP claim mapping. Around those, the Aura platform continues its monthly cadence: Cypher 25 picked up GROUP BY and a GQL cardinality function, quantized vector search reached general availability, and the Query editor gained persistent tabs.

bbotk is generalizing from an optimizer toolkit into an evaluation framework.

◆ Current state

bbotk is the black-box optimization backend behind mlr3 tuning: search spaces, terminators, archives, and an async layer built on rush. Recent releases pair steady async-API buildout with removal of the deprecated arguments that preceded it. The 1.9.0 release introduced EvalInstance as a base class for OptimInstance, separating evaluating an objective from optimizing one.

◆ Where it's heading

Two threads run through the visible history. The first is async optimization maturing: ArchiveAsync gained a full push/finish/fail vocabulary over rush tasks in 1.11.0, and 1.12.0 deleted the deprecated extra arguments it replaced. The second is dependency consolidation, with custom C hypervolume code handed to moocore and rush pinned to 1.0.0, trimming maintenance surface as the async path becomes the default.

◆ Prediction

The deprecation removals in 1.12.0 suggest the async archive API is now treated as settled; the next releases most likely build on EvalInstance rather than continuing to churn ArchiveAsync.

Neo4j moves its full graph algorithm catalog onto the free tier and adds attribute-based access control.

◆ Current state

Neo4j is pushing capability downward and outward at the same time. The complete Graph Data Science catalog — 65+ algorithms — now runs on AuraDB Free in isolated, unbilled sessions, while Business Critical and Virtual Dedicated Cloud tiers gain attribute-based access control with time-windowed permissions and IdP claim mapping. Around those, the Aura platform continues its monthly cadence: Cypher 25 picked up GROUP BY and a GQL cardinality function, quantized vector search reached general availability, and the Query editor gained persistent tabs.

◆ Where it's heading

The shape here is a funnel. Free-tier users get the algorithm catalog and hosted MCP access with no billing and no setup, which lowers the cost of the first serious graph experiment to nothing; enterprise tiers get the governance controls that make an expansion defensible. Cypher is simultaneously being pulled toward the GQL standard and extended with new surfaces — auth rules, grouping clauses — so the query language is absorbing work that used to sit in configuration and driver code.

◆ Prediction

Expect ABAC to descend to Professional tiers and the Aura Graph Analytics free session limits to become the pressure point Neo4j uses to convert experiments into paid capacity. The unresolved question from these entries is whether MCP for Aura reaches Virtual Dedicated Cloud, which is listed as pending.
