New Features

• A new option was defined for the overwrite_rule configuration to allow the file to be skipped and not transferred when destination already has a file with the same name. [client-side][sync] [#4709]
• The bundled OpenSSL libraries in Windows, Generic Linux, and OS X, were updated to version 1.1.1d. [#5348]

Defect Fixes
