 ## Backup Service
 * Added support for picking individual tables when creating a backup. (OPSC-17084)
 * Updated the AWS SDK version to `aws-java-sdk-s3:1.12.779`. To use the AWS CLI for bucket validation, set the `use_s3_cli` option to `true`. This option resolves issues when using some generic S3 providers, such as Cloudian. (OPSC-17639)
+* Fixed an issue with the restore dialog where clicking `All Keyspaces` before expanding the tree would result in no tables being selected. (OPSC-17669)
 
 ## Core
 * Upgraded the Apache Directory LDAP API to version `1.0.3` and the Apache MINA core library to version `2.0.27` to address a potential security vulnerability. (OPSC-17655)
