#### Filesearch on CentOS8 and RHEL8 instances

An issue has been fixed which prevented a correct filesearch on CentOS8 and RHEL8 backups with the xfs filesystem.

### Enhancements

A new configuration parameter`vault_s3_max_pool_connections`has been added to adjust the number of pool connections.\
The default value is 500.

This parameter can be set in the workloadmgr.conf on the Trilio appliance.

In the case of a Canonical installation this parameter is to be set in the tvault-object-store.conf in the workloadmgr container.

#### Default value for s3 read timeout has been decreased

The default value for the configuration parameter `vault_s3_max_pool_connections` has been reduced from 120 to 30.

This parameter can be set in the workloadmgr.conf on the Trilio appliance.

In the case of a Canonical installation this parameter is to be set in the tvault-object-store.conf in the workloadmgr container.

#### NFS mount process of datamover enhanced

A timeout with automatic process kill has been added to prevent high CPU usage from stale NFS mount operations in case of mounting errors.

#### Snapshot mount on Ubuntu 20.04

The documentation has been extended to support the usage of Ubuntu 20.04 cloud images for the Snapshot mount functionality.
