What is Neo4j?
Neo4j is turning the graph into something an agent can query without knowing Cypher.
Neo4j's releases this month converge on one goal: letting AI clients use a graph without a human writing Cypher. MCP for Aura is a hosted Model Context Protocol service built into the platform, with schema, read, and read-write tools and no server to run. Document Intelligence takes the other end — an assistant that reads PDF, DOCX, and EPUB files from cloud storage and proposes the node labels and relationships needed to model them as a graph. Around those, the enterprise track keeps shipping: self-service SSO with per-instance role mapping, Community-to-Aura migration in Fleet Manager, and monthly Enterprise Studio maintenance.
What is Delta Lake?
Delta Lake is handing table authority to Unity Catalog — under a feed buried in Databricks build tags.
The real releases in this window are 4.3.0 and its 4.3.1 patch. 4.3.0's headline is Spark talking to Unity Catalog through the UC Delta REST API, with server-side commit validation, server-advertised table features, and intent-based metadata updates; 4.3.1 fixes OAuth key case-sensitivity that broke Delta REST Catalog authentication, plus S3A fast listing and UC managed-table metadata handling. Everything else in the feed is a dbr-/dbi- kernel build tag cut from Databricks' internal build pipeline, several per week, with commit-message bodies and no user-facing content.

Neo4j
7.5ANALYTICS
Neo4j is turning the graph into something an agent can query without knowing Cypher.
◆ Current state
Neo4j's releases this month converge on one goal: letting AI clients use a graph without a human writing Cypher. MCP for Aura is a hosted Model Context Protocol service built into the platform, with schema, read, and read-write tools and no server to run. Document Intelligence takes the other end — an assistant that reads PDF, DOCX, and EPUB files from cloud storage and proposes the node labels and relationships needed to model them as a graph. Around those, the enterprise track keeps shipping: self-service SSO with per-instance role mapping, Community-to-Aura migration in Fleet Manager, and monthly Enterprise Studio maintenance.
◆ Where it's heading
Cypher is being repositioned from the interface to an implementation detail. Copilot now lints and EXPLAIN-retries its own generated queries and feeds the errors back to the model to correct hallucinated paths and inverted relationship directions — an admission that generated Cypher needs a verification loop before anyone runs it. Combined with the grounded-answers framing on MCP, Neo4j is arguing that a graph is the substrate that keeps agent answers accurate. The operational work reads as clearing the procurement objections that come with that pitch.
◆ Prediction
Virtual Dedicated Cloud support for MCP for Aura is stated as coming, and Document Intelligence should exit preview. The open question is whether read-write MCP access gains finer-grained permissions than the current three tools, given that IdP group-to-database-role mapping already exists on the SSO side.
Delta Lake
5.0ANALYTICS
Delta Lake is handing table authority to Unity Catalog — under a feed buried in Databricks build tags.
◆ Current state
The real releases in this window are 4.3.0 and its 4.3.1 patch. 4.3.0's headline is Spark talking to Unity Catalog through the UC Delta REST API, with server-side commit validation, server-advertised table features, and intent-based metadata updates; 4.3.1 fixes OAuth key case-sensitivity that broke Delta REST Catalog authentication, plus S3A fast listing and UC managed-table metadata handling. Everything else in the feed is a dbr-/dbi- kernel build tag cut from Databricks' internal build pipeline, several per week, with commit-message bodies and no user-facing content.
◆ Where it's heading
The protocol is moving from client-enforced to server-enforced: a catalog now validates commits and advertises which table features are in play, rather than every engine reasoning about the log independently. The stated intent is to extend that path to Flink, Trino, and other engines, which would make catalog integration — not log format — the thing that defines Delta compatibility. Both of the last two patch releases were spent on the authentication and metadata seams of that integration, which is where a new client-server boundary usually hurts first.
◆ Prediction
Expect the UC Delta REST API to reach a second engine, and for near-term patch releases to keep landing on catalog authentication and metadata edge cases rather than on the storage format itself.
