+## v1.18
+
+### Download
+https://github.com/vmware-tanzu/velero/releases/tag/v1.18.0
+
+### Container Image
+`velero/velero:v1.18.0`
+
+### Documentation
+https://velero.io/docs/v1.18/
+
+### Upgrading
+https://velero.io/docs/v1.18/upgrade-to-1.18/
+
+### Highlights
+#### Concurrent backup
+In v1.18, Velero is capable to process multiple backups concurrently. This is a significant usability improvement, especially for multiple tenants or multiple users case, backups submitted from different users could run their backups simultaneously without interfering with each other.  
+
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/concurrent-backup-processing.md for more details.
+
+#### Cache volume for data movers
+In v1.18, Velero allows users to configure cache volumes for data mover pods during restore for CSI snapshot data movement and fs-backup. This brings below benefits:
+- Solve the problem that data mover pods fail to when pod's ephemeral disk is limited
+- Solve the problem that multiple data mover pods fail to run concurrently in one node when the node's ephemeral disk is limited
+- Working together with backup repository's cache limit configuration, cache volume with appropriate size helps to improve the restore throughput
+
+Check design https://github.com/vmware-tanzu/velero/blob/main/design/Implemented/backup-repo-cache-volume.md for more details.
+
+#### Incremental size for data movers
+In v1.18, Velero allows users to observe the incremental size of data movers backups for CSI snapshot data movement and fs-backup, so that users could visually see the data reduction due to incremental backup.
+
+#### Wildcard support for namespaces
+In v1.18, Velero allows to use Glob regular expressions for namespace filters during backup and restore, so that users could filter namespaces in a batch manner.
+
+#### VolumePolicy for PVC phase
+In v1.18, Velero VolumePolicy supports actions by PVC phase, which help users to do special operations for PVCs with a specific phase, e.g., skip PVCs in Pending/Lost status from the backup.  
+
+#### Scalability and Resiliency improvements
+##### Prevent Velero server OOM Kill for large backup repositories
+In v1.18, some backup repository operations are delay executed out of Velero server, so Velero server won't be OOM Killed.
+
+#### Performance improvement for VolumePolicy
+In v1.18, VolumePolicy is enhanced for large number of pods/PVCs so that the performance is significantly improved.
+
+#### Events for data mover pod diagnostic
+In v1.18, events are recorded into data mover pod diagnostic, which allows user to see more information for troubleshooting when the data mover pod fails.
+
+### Runtime and dependencies
+Golang runtime: 1.25.7  
+kopia: 0.22.3
+
+### Limitations/Known issues
+
+### Breaking changes
+#### Deprecation of PVC selected node feature
+According to [Velero deprecation policy](https://github.com/vmware-tanzu/velero/blob/main/GOVERNANCE.md#deprecation-policy), PVC selected node feature is deprecated in v1.18. Velero could appropriately handle PVC's selected-node annotation, so users don't need to do anything particularly.

-Implement wildcard namespace pattern expansion for backup namespace includes/excludes.
-
-This change adds support for wildcard patterns (*, ?, [abc], {a,b,c}) in namespace includes and excludes during backup operations. 
-When wildcard patterns are detected, they are expanded against the list of active namespaces in the cluster before the backup proceeds.
-
-Key features:
-- Wildcard patterns in namespace includes/excludes are automatically detected and expanded
-- Pattern validation ensures unsupported patterns (regex, consecutive asterisks) are rejected
-- Empty wildcard results (e.g., "invalid*" matching no namespaces) correctly result in empty backups
-- Exact namespace names and "*" continue to work as before (no expansion needed)
