π New features
There are no new features with this release.
β¨ Enhancements
Increased Transfer speed between Enterprise Updater nodes
We've increased the transfer speed between Enterprise Updater nodes by increasing the chunk size from 32KB to 2MB, resulting in a big boost in download speedsβfrom 5β6β―MB/s to over 200β―MB/s!
Reduced amount of re-downloads for files that have been already installed
Delete everything EXCEPT the highest installed version
Downloads were being re-downloaded after 30 days due to automatic cache cleanup, which caused extra traffic.
We've updated the cache settings to help reduce unnecessary re-downloads.
Modified description of the Clear Cache button
Updated the Clear Cache button to include verbiage that clearing the cache won't delete currently installed products.
Provide user feedback for the Clear Cache feature
The Clear Cache feature now provides user feedback, showing when it's in progress and when it's completed.
You'll also see a message in the activity log: βCache cleared successfully with purge days.β
π οΈ Issues resolved
| Description | Resolution |
|---|---|
| The updater relies on supi.exe file version instead of the product GUID to detect the installed SUPI engine version, causing it to misidentify manually installed versions and perform unnecessary reinstallation during updates. | Manually installed versions are no longer misidentified and reinstallation does not occur during updates. |
| The 3.5 version of Updater does not detect or display a pending reboot banner when specific reboot-related registry keys are manually created, unlike version 4.4.1 of the Appliance software, leading to inconsistent reboot behavior and potential surprises for users. | Reboot behavior is no longer inconsistent and works as intended. |
π Requirements
- .NET 4.7.2 or later
- IIS to be enabled on host
