+# Release 450 (19 Jun 2024)
+
+## General
+
+* Add support for specifying an Azure blob endpoint for accessing spooling in
+  fault-tolerant execution with the `exchange.azure.endpoint` configuration
+  property. ({issue}`22218`)
+* Expose driver execution statistics via JMX. ({issue}`22427`)
+* Improve performance of the {func}`first_value` and {func}`last_value`
+  functions. ({issue}`22092`)
+* Improve performance for large clusters under heavy workloads. ({issue}`22039`)
+* Improve performance of queries with simple predicates. This optimization can
+  be disabled using the `experimental.columnar-filter-evaluation.enabled`
+  configuration property or the `columnar_filter_evaluation_enabled` session
+  property. ({issue}`21375`)
+* {{breaking}} Improve performance of aggregations containing a `DISTINCT`
+  clause, and replace the `optimizer.mark-distinct-strategy` and
+  `optimizer.optimize-mixed-distinct-aggregations` configuration properties with
+  the new `optimizer.distinct-aggregations-strategy` property. ({issue}`21907`)
+* Improve performance of reading JSON files. ({issue}`22348`)
+* Improve performance for the {func}`date_trunc`, {func}`date_add`, and
+  {func}`date_diff` functions. ({issue}`22192`)
+* Fix failure when loading the [](/admin/event-listeners-openlineage). ({issue}`22228`)
+* Fix potential incorrect results when metadata or table data in certain
+  connectors is updated or deleted. ({issue}`22285`)
+
+## Security
+
+* Add support for using web identity exclusively for authentication when running
+  on Amazon EKS with the legacy S3 file system enabled. This can be configured
+  via the `trino.s3.use-web-identity-token-credentials-provider` property. ({issue}`22162`)
+* Add support for exclusively using web identity for authentication when using
+  Amazon EKS with
+  [IAM roles](https://docs.aws.amazon.com/eks/latest/userguide/iam-roles-for-service-accounts.html)
+  by setting the
+  `s3.use-web-identity-token-credentials-provider` configuration property. ({issue}`22163`)
+
+## JDBC driver
+
+* Add support for the `assumeNullCatalogMeansCurrent` connection property. When
+  enabled, a `null` value for the `catalog` parameter in `DatabaseMetaData`
+  methods is assumed to mean the current catalog. If no current catalog is
+  set, the behaviour is unmodified. ({issue}`20866`)
+
+## BigQuery connector
+
+* Add support for metadata caching when the
+  `bigquery.case-insensitive-name-matching` configuration property is enabled. ({issue}`10740`)
+* {{breaking}} Automatically configure BigQuery scan parallelism, and remove the
+  `bigquery.parallelism` configuration property. ({issue}`22279`)

+## Cassandra connector
+
+* Fix incorrect results when specifying a value for the
+  `cassandra.partition-size-for-batch-select` configuration property. ({issue}`21940`)
+
+## ClickHouse connector
+
+* Improve performance of `ORDER BY ... LIMIT` on non-textual types by pushing
+  execution down to the underlying database. ({issue}`22174`)
+
+## Delta Lake connector
+
+* Add support for concurrent `UPDATE`, `MERGE`, and `DELETE` queries. ({issue}`21727`)
+* Add support for using table statistics with `TIMESTAMP` types. ({issue}`21878`)
+* Add support for reading tables with
+  [type widening](https://docs.delta.io/latest/delta-type-widening.html). ({issue}`21756`)
+* Set the default value for the `s3.max-connections` configuration property
+  to 500. ({issue}`22209`)
+* Fix failure when reading a `TIMESTAMP` value after the year 9999. ({issue}`22184`)
+* Fix failure when reading tables with the unsupported `variant` type. ({issue}`22310`)

+  coercion in unpartitioned tables. ({issue}`22246`, {issue}`22293`)
+* Add support for `double` to `varchar` type coercion in unpartitioned tables
+  using Parquet files. ({issue}`22277`)
+* Add support for `float` to `varchar` type coercion. ({issue}`22291`)
