 For users convenience, this release introduces new decorators for non-item streams as well. With this new feature, all
 item readers and writers in Spring Batch can now be synchronized without having to write custom decorators.

+[[new-cursor-based-mongo-item-reader]]
+=== New Cursor-based MongoItemReader
+
+Up to version 5.0, the `MongoItemReader` provided by Spring Batch used pagination, which is based on MongoDB's `skip` operation.
+While this works well for small/medium data sets, it starts to perform poorly with large data sets.
+
+This release introduces the `MongoCursorItemReader`, a new cursor-based item reader for MongoDB. This implementation
+uses cursors instead paging to read data from MongoDB, which improves the performance of reads on large collections.
+For consistency with other cursor/paging readers, the current `MongoItemReader` has been renamed to `MongoPagingItemReader`.
+
+[[bulk-inserts-support-mongo-item-writer]]
+=== Bulk inserts support in MongoItemWriter
+
+Up to version 5.0, the `MongoItemWriter` supported two operations: `upsert` and `delete`. While the `upsert`
+operation works well for both inserts and updates, it does not perform well for items that are known to be new
+in the target collection.
+
+Similar to the `persist` and `merge` operations in the `JpaItemWriter`, this release adds a new operation named
+`insert` in the `MongoItemWriter`, which is designed for bulk inserts. This new option performs better than
+`upsert` for new items as it does not require an additional lookup to check if items already exist in the target collection.
