+* Add support for {func}`extract` for `timestamp(p) with time zone` with values of `p` other than 3. ({issue}`4867`)
+* Add support for correlated subqueries in recursive queries. ({issue}`4877`)
+* Add [](optimizer_rule_stats) system table. ({issue}`4659`)

+* Remove the `deprecated.legacy-timestamp` configuration property and the `legacy_timestamp` session property. ({issue}`4799`)
+* Change timestamp operations to match the SQL specification. The value of a `TIMESTAMP` 
+  type is not affected by the session time zone. ({issue}`37`)
+* Preserve precision when applying `AT TIME ZONE` to values of type `TIMESTAMP`. ({issue}`4866`)
+* Fix serialization of `NULL` values in `ROW`, `MAP` and `ARRAY` types for old Presto clients. ({issue}`4778`)

+* Fix parsing failure of timestamps due to daylight saving changes. ({issue}`37`)
+* Fix failure when calling {func}`extract` with `TIMEZONE_HOUR` and `TIMEZONE_MINUTE` for 
+  `TIMESTAMP WITH TIME ZONE` type. ({issue}`4867`)
+* Fix query deadlock for connectors that wait for dynamic filters. ({issue}`4946`)
+* Fix failure when `TIME` or `TIMESTAMP` subtraction returns a negative value. ({issue}`4847`)
+* Fix failure when duplicate expressions appear in `DISTINCT` clause. ({issue}`4787`)
+* Fix failure for certain join queries during spilling or when available memory is low. ({issue}`4994`)
+* Fix issue where the `query_max_scan_physical_bytes` session property was ignored if
+  the `query.max-scan-physical-bytes` configuration property was not defined. ({issue}`5009`)
+* Correctly compute sample ratio when `TABLESAMPLE` is used with a fractional percentage. ({issue}`5074`)
+* Fail queries with a proper error message when `TABLESAMPLE` is used with a non-numeric sample ratio. ({issue}`5074`)
+* Fail with an explicit error rather than `OutOfMemoryError` for certain operations. ({issue}`4890`)
+
+## Security Changes
+
+* Add [Salesforce password authentication](/security/salesforce). ({issue}`4372`)
+* Add support for interpolating [secrets](/security/secrets) into `access-control.properties`. ({issue}`4854`)
+* Only request HTTPS client certificate when certificate authentication is enabled. ({issue}`4804`)
+* Add {doc}`/security/user-mapping` support for uppercasing or lowercasing usernames. ({issue}`4736`)
+
+## Web UI
+
+* Fix display of physical input read time in detailed query view. ({issue}`4962`)
+
+## JDBC Driver Changes
+
+* Implement `ResultSet.getStatement()`. ({issue}`4957`)
+
+## BigQuery Connector Changes
+
+* Add support for hourly partitioned tables. ({issue}`4968`)
+* Redact the value of `bigquery.credentials-key` in the server log. ({issue}`4968`)
+
+## Cassandra Connector Changes
+
+* Map Cassandra `TIMESTAMP` type to Presto `TIMESTAMP(3) WITH TIME ZONE` type. ({issue}`2269`)
+
+## Hive Connector Changes
+
+* Skip stripes and row groups based on timestamp statistics for ORC files. ({issue}`1147`)
+* Skip S3 objects with the `DeepArchive` storage class (in addition to the `Glacier`
+  storage class) when `hive.s3.skip-glacier-objects` is enabled. ({issue}`5002`)
+* Use a temporary staging directory for temporary files when writing to sorted bucketed tables.
+  This allows using a more efficient file system for temporary files. ({issue}`3434`)
+* Fix metastore cache invalidation for `GRANT` and `REVOKE`. ({issue}`4768`)
+* Add Parquet and RCBinary [configuration properties](hive_configuration_properties) `hive.parquet.time-zone` 
+  and `hive.rcfile.time-zone` to adjust binary timestamp values to a specific time zone. For Hive 3.1+, this 
+  should be set to UTC. The default value is the JVM default time zone, for backwards compatibility with 
+  earlier versions of Hive. ({issue}`4799`)
+* Add ORC [configuration property](hive_configuration_properties) `hive.orc.time-zone` to set the default 
+  time zone for legacy ORC files that did not declare a time zone. ({issue}`4799`)
+* Replace the `hive.time-zone` configuration property with format specific properties: `hive.orc.time-zone`, 
+  `hive.parquet.time-zone`, `hive.rcfile.time-zone`. ({issue}`4799`)
+* Allow using the cluster default role with S3 security mapping. ({issue}`4931`)
+* Remove support for bucketing on timestamp. The definition of the hash function for timestamp
+  incorrectly depends on the storage time zone and can result in incorrect results. ({issue}`4759`)
+* Decrease the number of requests to the Glue metastore when fetching partitions.
+  This helps avoid hitting rate limits and decreases service costs. ({issue}`4938`)
+* Match the existing user and group of the table or partition when creating new files on HDFS. ({issue}`4414`)
+* Fix invalid timestamp values for nested data in Text, Avro, SequenceFile, JSON and CSV formats. ({issue}`4799`)
+* Fix query failure when reading an ORC ACID table with a filter after the table 
+  underwent a minor table compaction. ({issue}`4622`)
+* Fix incorrect query results when reading an ORC ACID table that has deleted rows 
+  and underwent a minor compaction. ({issue}`4623`)
+* Fix query failure when storage caching is enabled and cached data is evicted during query execution. ({issue}`3580`)
+* Fix incorrect results when filtering on columns of `TIMESTAMP` type. ({issue}`5083`)
+
+## JMX Connector Changes
+
+* Change `timestamp` column type in history tables to `TIMESTAMP WITH TIME ZONE`. ({issue}`4753`)
+
+## Kafka Connector Changes
+
+* Preserve time zone when parsing `TIMESTAMP WITH TIME ZONE` values. ({issue}`4799`)
+
+## Kinesis Connector Changes
+
+* Preserve time zone when parsing `TIMESTAMP WITH TIME ZONE` values. ({issue}`4799`)
+
+## Kudu Connector Changes
+
+* Fix delete when applied on table having primary key of decimal type. ({issue}`4683`)
+
+## Local File Connector Changes
+
+* Change `timestamp` column type to `TIMESTAMP WITH TIME ZONE`. ({issue}`4752`)
+
+## MySQL Connector Changes
+
+* Improve performance of aggregation queries by pushing the aggregation computation into the MySQL database.
+  Currently, the following aggregate functions are eligible for pushdown: `count`,  `min`, `max`,
+  `sum` and `avg`. ({issue}`4138`)
+
+## Oracle Connector Changes
+
+* Add `oracle.connection-pool.inactive-timeout` configuration property to specify how long
+  pooled connection can be inactive before it is closed. It defaults to 20 minutes. ({issue}`4779`)
+* Add support for database internationalization. ({issue}`4775`)
+* Add resilience to momentary connection authentication issues. ({issue}`4947`)
+* Allowing forcing the mapping of certain types to `VARCHAR`. This can be enabled by
+  setting the `jdbc-types-mapped-to-varchar` configuration property to a comma-separated
+  list of type names. ({issue}`4955`)
+* Prevent query failure for pushdown of predicates involving a large number of conjuncts. ({issue}`4918`)
+
+## Phoenix Connector Changes
+
+* Fix overwriting of former value when insert is applied without specifying that column. ({issue}`4670`)
+
+## Pinot Connector Changes
+
+* Add support for `REAL` and `INTEGER` types. ({issue}`4725`)
+* Add support for functions in pass-through queries. ({issue}`4801`)
+* Enforce a limit on the number of rows fetched from Pinot. This can be configured via the 
+  `pinot.max-rows-per-split-for-segment-queries` configuration property. ({issue}`4723`)
+* Fix incorrect results for `count(*)` queries. ({issue}`4802`)
+* Fix incorrect results for queries involving {func}`avg` over columns of type `long`, `int`, or `float`. ({issue}`4802`)
+* Fix incorrect results when columns in pass-through query do not match selected columns. ({issue}`4802`)
+
+## Prometheus Connector Changes
+
+* Change the type of the `timestamp` column to `TIMESTAMP(3) WITH TIME ZONE` type. ({issue}`4799`)
+
+## PostgreSQL Connector Changes
+
+* Improve performance of aggregation queries with predicates by pushing the computation
+  of both the filtering and aggregations into the PostgreSQL server where possible. ({issue}`4111`)
+* Fix handling of PostgreSQL arrays when `unsupported-type-handling` is set to `CONVERT_TO_VARCHAR`. ({issue}`4981`)
+
+## Raptor Connector Changes
+
+* Remove the `storage.shard-day-boundary-time-zone` configuration property, which was used to work 
+  around legacy timestamp semantics in Presto. ({issue}`4799`)
+
+## Redis Connector Changes
+
+* Preserve time zone when parsing `TIMESTAMP WITH TIME ZONE` values. ({issue}`4799`)
+
+## SPI Changes
+
+* The `TIMESTAMP` type is encoded as a number of fractional seconds from `1970-01-01 00:00:00` in the proleptic 
+  Gregorian calendar. This value is no longer adjusted to the session time zone. Timestamps with precision less 
+  than or equal to 3 are now represented in microseconds. ({issue}`4799`)
+* Remove `isLegacyTimestamp()` from `ConnectorSession`. ({issue}`4799`)
+* Enable connectors to wait for dynamic filters before producing data on worker nodes. ({issue}`3414`)
