Release Note for Neo4j 2026.01.3 (4 Feb 2026)

 

Important Notice

We have identified a bug in Dynamic Node Labels and Dynamic Relationship Types when used with composite (multi-property) indexes which can lead to the operator sometimes returning incorrect MATCH results.  This can potentially result in updates to the incorrect node, or in the runtime issuing CREATE operations that cannot succeed. This bug was introduced in 2025.11.  A fix will be released shortly, but in the meantime we advise customers not to use Dynamic Label/Relationship Types in conjunction with composite indexes.    

Server

General

  • Public preview: Vector search with filters supported by in-index filtering and new Cypher syntax for querying vectors. See blog post.
  • Improved reuse of deleted space for big property values in block format. See Operations Manual -> Space reuse.
  • New metric transaction.rollbacks_deadlocked, a counter that shows the total number of transactions that were rolled back due to being deadlocked. See Operations Manual -> Metrics reference.

Security

  • General Availability (GA) release of Auth Token Passthrough – Add OIDC credential forwarding as an authentication method to remote database aliases. The column credentials is added to SHOW ALIAS, which shows what type of credentials are used for remote database aliases. See Operations Manual -> Database administration -> Configuring remote database aliases.
  • The plain text query log now escapes potentially dangerous unicode characters to avoid log injection.
  • added a new configuration flag “db.logs.query.obfuscate_errors” which obfuscates errors from the query log

Neo4j-admin

  • Improved path pattern matching for –nodes and –relationships files used by neo4j-admin database import with new parameter –path-pattern-style. See Operations Manual – Import. Possible values are:
    • glob — allows you to write patterns like /some/**/deep/**/nested/structure.*.
    • regex — allows you to write regular expressions, i.e. /some/nested/structure.*.
    • none — you have to enumerate all the file paths exactly, i.e. /some/content/structure1.csv,/some/content/structure2.csv.

Cypher-shell

Platforms

  • Red Hat Enterprise Linux Server 10.x and CentOS Stream 10.x are now supported platforms. See Operations Manual -> System requirements for details.
  • CentOS Stream 8.x is now deprecated, with support for this platform being removed in a future release.
  • Container images will now default to use updated Operating Systems. Debian container images now default to using Debian 13 (Trixie) while Red Hat UBI images will default to UBI10. See Operations Manual -> Getting started with Neo4j in Docker for details.

Infinigraph

  • A new safety mechanism in Infinigraph deployments to prevent potential data corruption. This mechanism prevents property shard replicas from falling behind by putting the sharded property database into read-only mode. Guidance for identifying and resolving this condition is provided in the Operations Manual -> Transaction log pruning and recovery.
 

Cypher

Cypher 25 additive features

  • Introduced a query size limit for a query to be considered for query caching. This limit is used to prevent large generated query text strings from occupying memory in the query cache. Such query strings often contain inlined data, and are unlikely to be reusable before auto-parameterization of literals is applied. The default query size limit is 128 KiB of query text. To circumvent the default, prefix the query with either CYPHER cache=force to always cache it, or CYPHER cache=skip to never cache it and skip the query cache lookup. As a best practice, avoid passing data in the query text string and use parameters instead.
 

Bug fix

Server

  • Fixed a bug when deleting a relationship property that was added or changed in the same transaction, that could sometimes cause a NullPointerException and fail the transaction.

Cypher

  • Fixed stack overflows when traversing long lists constructed by append/prepend
  • Fixed a bug where SHORTEST 1 would return a path shorter than the lower bound of the variable-length pattern.
  • Fixed issue with conditional query WHEN not aggregating null values correctly without a grouping key
  Please refer to the changelog for full details of the changes.
