This may be the problem I had when I tried to update to 5.6.3. from 5.6.1. I'm in the middle of a project and did not have time to figure out what was causing the problem. The only change was the change to the MapServer version so I quickly reverted back. I'm using PHP Mapscript. I'll see if I can find the time to check to see if this is the problem I was having.

I don't know if it's really a bug, but it contradicts the documentation, in which the tileindex argument is optional, and it wasn't behaving like that (to my knowledge) with MS in [5.6.0, 5.6.2]. By the way, an initial observation I made was wrong: it also affects the PHP version, and the workaround is the same.
