Bakflip MX4, which model is which?

Short of it; how do you tell the difference in newest and oldest versions of the Bakflip MX4.

I ordered a Bakflip from Yotaxpedition.
The issue is, whatever is on the site (the cover locking mechanism, the drain hose etc) seems to show better engineering and my concern is the model sent was and older version etc.
The nicer, more detailed pictures of course are the website, the more plain are the instruction to the model I received.
On one hand I 100% get it, things change quickly in retail and it is expensive and time consuming to go back and constantly update the pictures for every model as those changed occur to every damn item you might carry as a vendor. I just am trying to figure out which version I have.

I received the following locking system:

The website shows this locking system:


the drainage hose was "drill out holes to fit the 5/8th hose:


whereas the web site photos show the version of the hose that has been tapered down to fit in the holes precut in a Tundra bed.

Last but not least, the cover I recieved has a plastic "good luck" strap holder whereas the version on the website has a much better engineered female snap to hold the cover strap:

 

I may have answered my own questions on the realtruck site. Their current video installing on a 2024 truck shows the model I was sent with the clamps that resemble the below picture.
So if you are trying to figure out what version is new, the newer version has the below locking system.
