+# Percona Backup for MongoDB 2.14.0 ({{date.2_14_0}})
+
+- [Installation](../installation.md){.md-button}
+
+
+Percona Backup for MongoDB (PBM) is a distributed, low-impact solution for creating consistent backups of MongoDB sharded clusters and replica sets, and restoring them to a specific point in time.
+
+## Release highlights
+
+=== "🖥️ Interactive confirmation prompt"
+
+    !!! warning "Breaking change"
+
+        Since an interactive prompt is now printed, automation and scripts must use the `-y` flag to bypass this confirmation (same as for delete operations).
+
+
+    ### Interactive confirmation for restore
+    To reduce the risk of accidental or unintended restores, `pbm restore` command now includes an interactive confirmation prompt. This requires explicit user approval before a restore action is executed.
+
+    This change addresses scenarios where users might inadvertently re‑run a previous restore command from shell history, potentially restoring the wrong backup to production. With the new confirmation step, restores are safer and less prone to human error.
+
+    ```bash
+    $ pbm restore <backup-name>
+
+    You are about to restore backup '<backup-name>' to the current cluster.
+    This operation may overwrite existing data.
+
+    Do you want to continue? [y/N]: 
+    ```
+
+=== "⚡ Optimized backup uploads"
+
+    ### Concurrent streaming for faster MinIO uploads
+
+    This release introduces support for the `ConcurrentStreamParts` option when uploading files to MinIO storage. By enabling concurrent part uploads, large file transfers can achieve improved throughput and efficiency.
+
+    To ensure reliability, PBM includes built‑in optimizations and fallbacks:
+
+    - **Small files:** If the file is smaller than the upload part size, concurrent upload is automatically disabled (since it’s unnecessary).
+
+    - **Empty streams:** If the MinIO library reports an unexpected error for empty streams, PBM will retry the request with ConcurrentStreamParts disabled.
+
+    These safeguards ensure that concurrent uploads deliver performance benefits without compromising stability.
+
+    ??? example "Example"        
+
+        ```yaml
+        storage:
+        type: minio
+        endpointUrl: https://minio.example.com
+        bucket: pbm-backups
+        credentials:
+            accessKey: <ACCESS_KEY>
+            secretKey: <SECRET_KEY>
+        concurrentStreamParts: true
+        ```
