it confirms if i want to delete the file now. previously i had "direct to trash".

You must be using Windows.
From the news page:
• removed support for sending removed transfer files to trash on Windows version due to bad fallback behavior in API

well that mega sucks, thats like basic functionality missing. i would still like to have it even if its buggy. on my windows 10 it worked perfectly. maybe notify thats it is buggy and keep it? wait for sulution from windows/sdk?

or could there be at least a functionality like a "move to specific folder on delete" which simulates recycle bin? for each category?
1. i dont like a confirmation, i dont like too many clicks
2. i dont like my files staying if i remove the torrent

WinXP Integral Edition and Win11 23h2 have never had any problems with deleting files to the trash.
Instead of complete removing the deleting behavior settings, it is better to make an appropriate warning on problem versions of the system in the settings panel or pop-up when using.

Tixati was the best program I've ever found. But this is a dealbreaker for me. Now I have to use a program that I hate. But it sends deleted files to the Recycle Bin...

Never had an issue with the functionality on Win10 either.

What exactly is the "bad fallback behavior in API" that is sought to be avoided with the removal of this useful option?

If the trash is full or not big enough when you send something to the trash it will be deleted instead.
