Recent developments have stirred controversy around the latest update of the file synchronization utility, rsync 3.4.3. While the update addressed 6 vulnerabilities, users have reported encountering regressions that impact the performance of their previous configurations. Additionally, frustration arose from the incorporation of approximately 50 changes to the rsync repository over the past two weeks, generated using the Claude AI model. Some users have speculated that the emergence of regressions may be linked to the utilization of AI for developing vulnerability fixes.
Several regressions have been identified in rsync 3.4.3, including issues with incremental backup commands that specified multiple “–compare-dest” options failing to execute properly. Additionally, certain functionalities have become impossible to achieve with the updated version.
