⭐ New Features

• GQLStatusObjects have been stabilized as a replacement for the deprecated Notifications. #1285
• The GQL-compliant properties gqlStatus, gqlStatusDescription, diagnosticRecord, classification and rawClassification on Neo4jError and GQLError have been stabilized. #1286

👏 Improvements

---

• sideEffects has been set to false in the package.json, this will allow tree-shaking to remove dead code. #1303
• Added documentation to members of GQLError and Neo4jError. #1300
• The timeout set with the connectionAcquisitionTimeout config option now covers the whole process of acquiring a connection, including preceding routing calls. This is to align with the behavior of other languages. #1292
• Duration toString() format has been updated to align with the stringification in Cypher. #1284

🔧 Fixes

---

• The seconds and nanoseconds properties on Duration objects will now not be neo4j.Integer typed if the driver is configured to return native JS numbers or BigInts. #1265

❌ Removals

---

• severity has been removed from the Notification class. #1289

👎 Deprecation

---

• Deprecated Date.toStandardDate() due to the unclear handling of timezones. Date.toStandardDateLocal() is a drop in replacement, but Date.toStandardDateUTC() may be more desireable to some users. #1290
• ResultTransformers .eagerResultsTransformer() and .mappedResultsTransformer() have been deprecated. .eager() and .mapped() are drop in replacements. #1287
• Notifications and related functions have been deprecated in favor of the newly stabilized GQLStatusObjects. #1285
