Neo4j Aura Database October Release Update

The Neo4j Aura October release is now rolling out—starting with AuraDB Free and gradually extending to higher-tier instances.

🚀 New Cypher Features

VECTOR

Type Support
: We've introduced
VECTOR
as a new supported type in Cypher, Block store format and v6 drivers.
Construct Temporals from Strings
: You can now construct temporal values (like dates and times) from formatted strings, with the option to provide patterns for the conversion. This complements the feature to format temporal values into strings in last month's release.

🛠️ Improvements

Better Error Highlighting
: To help you debug faster, Cypher errors in JSON query logs and cypher-shell will now
display the query string along with a position marker
pointing to where the error occurred.

🐞 Bug Fixes

Cypher
: We now allow using
null
as a default value for non-primitive procedure parameters, and fixed a bug where values in the options maps for
CREATE INDEX
and
CREATE CONSTRAINTS
could be transposed.
Server
: A rare issue was fixed where malformed tokens (like empty strings) could bypass validation and cause a database panic, and a stack overflow error is now prevented when sorting free IDs for big value store.
