Here's what's new:
Drag-and-drop support on file upload page.
Super straightforward. Simply drag a file anywhere onto the upload page and it should automatically populate the upload form. There's also a little hint on the upload page informing the user of this capability.
Display a proper error message should encryption fail.
Previously the frontend would show the "Encrypting"-spinner indefinitely even if encryption failed and an error was thrown in the browser console. Now the user will be informed with an appropriate error message.
Enforce the 2GiB maximum filesize limit.
I've done a little more testing and determined that the WebCrypto-API limits message sizes to 2GiB, thereby effectively limiting the maximum filesize to 2GiB. This release enforces this limit during configuration setup and application startup.
