 # Change Log
 All notable changes to the Zowe CLI package will be documented in this file.
 
+
+## Recent Changes
+
+- BugFix: The `zowe zos-files copy data-set` command overwrites the contents of the target data set without user confirmation. A `--safe-replace` option was added which prompts the user to confirm before overwriting the contents of the target data set. [#2369] (https://github.com/zowe/zowe-cli/issues/2369)
+
 ## `8.12.0`
+
 - Enhancement: The `zowe zos-files copy data-set` command no longer requires the target data set to be preallocated. [##2349] (https://github.com/zowe/zowe-cli/issues/2349)
 
 ## `8.10.4`

 - Enhancement: The `Copy.dataset` function now creates a new data set if the entered target data set does not exist. [#2349](https://github.com/zowe/zowe-cli/issues/2349)
