 Prestissimo (Native Execution) Changes
 ______________________________________
 * Fix Native Plan Checker for CTAS and Insert queries. `#25115 <https://github.com/prestodb/presto/pull/25115>`_
 * Fix native session property manager reading plugin configs from file. `#25553 <https://github.com/prestodb/presto/pull/25553>`_
 * Fix PrestoExchangeSource 400 Bad Request by adding the "Host" header. `#25272 <https://github.com/prestodb/presto/pull/25272>`_
 * Improve memory usage in PartitionAndSerialize Operator by pre-determining the serialized byte size of a given sort key at ``rowId``. This allows the PartitionAndSerialize Operator to pre-allocate the exact output buffer size needed for serialization and avoid wasted memory allocation. User should expect lower memory usage and up to 20% runtime increase when serializing a sort key. `#25393 <https://github.com/prestodb/presto/pull/25393>`_
-* Improve serialized size estimation by introducing a batched API using vectorized operations. It delivers up to 8x faster size estimation compared to the previous row-by-row implementation. Workloads with high serialization cost will benefit from adopting this range-based API. `#25569 <https://github.com/prestodb/presto/pull/25569>`_
-* Add BinarySortableSerializer::serializedSizeInBytes method that returns the serialized byte size of a given input row at ``rowId``. This allows us to pre-allocate the exact output buffer size needed for serialization, avoiding wasted memory space. `#25359 <https://github.com/prestodb/presto/pull/25359>`_
+* Improve the efficiency of queries that involve with serialization operator by processing data in large groups instead of one by one. `#25569 <https://github.com/prestodb/presto/pull/25569>`_
 * Add geometry type to the list of supported types in NativeTypeManager. `#25560 <https://github.com/prestodb/presto/pull/25560>`_
-* Add sidecar in presto-native-tests module. `#25174 <https://github.com/prestodb/presto/pull/25174>`_
-* Replace ``EXPLAIN (TYPE DISTRIBUTED)`` with ``EXPLAIN (TYPE VALIDATE)`` for faster, lightweight analysis. `#25545 <https://github.com/prestodb/presto/pull/25545>`_
-* Update thrift IDL to expand connector specific fields. `#25474 <https://github.com/prestodb/presto/pull/25474>`_
 * Update stats API and Presto UI to report number of drivers and splits separately. `#24671 <https://github.com/prestodb/presto/pull/24671>`_

 * Replace the parameters in router schedulers to use `RouterRequestInfo` to get the URL destination. `#25244 <https://github.com/prestodb/presto/pull/25244>`_
+* Replace ``EXPLAIN (TYPE DISTRIBUTED)`` with ``EXPLAIN (TYPE VALIDATE)`` for faster, lightweight analysis. `#25545 <https://github.com/prestodb/presto/pull/25545>`_
 * Update router UI to eliminate vulnerabilities. `#25206 <https://github.com/prestodb/presto/pull/25206>`_
