External Release Notes: Smart Cache v5.1.2 (May 30, 2025)
New Features And Enhancements
Allowlist Or Whitelist Public IP Addresses For Smart Cache Devices
Egnyte now allows users to allowlist or whitelist public IP addresses for Smart Cache device authentication to enhance security. This feature helps prevent unauthorized access by restricting authentication to trusted networks.
The option will be available to the customers using Smart Cache v5.1.2 or higher. If a factory reset of the appliance is performed, the new setup configuration screen will be displayed for Smart Cache v5.1.2.
AutoCAD Support In SMB Mode - Information Available In Device Setup
The device setup screen in Smart Cache now includes details about AutoCAD support in SMB Collaboration mode, available under the Advanced Configuration section.

Issues Addressed
Removing Synced Folders When Device Is Out Of Disk Space
Smart Cache devices were not able to remove synced folders when disk space was full, preventing users from clearing space and managing sync settings independently.
Unhealthy State During An Renamed File Upload
Under very rare conditions, the device would enter an unhealthy state when a file rename failed to upload due to an internal error.
Device Going To Internal Error State After Reauthorizing The Device
Under a few rare conditions, when an end user attempted to reauthorize the Smart Cache device, they would receive either an "Authentication code is invalid" or "Access token is invalid" error. Although subsequent reauthorization attempts would succeed, the device would then enter an "Internal error state."
Device Going To Unhealthy State With Push Error
In some edge cases, renaming operations result in push errors on the device, which subsequently causes the device to enter an unhealthy state with internal error.
Device Getting Connected To Desktop App When Configured In SMB Mode
In some rare race conditions, a device configured in SMB mode would connect to the Desktop App, which should not occur.
File Conflicts Originating from Smart Cache Under Rare Scenarios
In a rare scenario, where a file is saved multiple times within 1 second, the ensuing file versions do not get ordered properly when uploaded by Smart Cache. We have now fixed this issue to handle sub-second file-saves.
Memory Corruption Issue
A memory corruption issue caused by the double freeing of allocated memory is now fixed.
SMB Configured Device Upgrade Failure in Rare Scenarios
In rare cases, upgrading SMB-configured devices from older Smart Cache versions may fail, causing the devices to go offline.
