Do you have any experience with Joomla 5.4... or whether the current version of jdownloads is fully compatible?
The component appears to be compatible, but compatibility cannot be determined for all plugins and modules.
I updated from Joomla 5.34 to 5.4.
As a precaution, i deactivated all jDownloads components, modules, and plugins beforehand.
The update went smoothly, and everything is working fine so far.
