Help in deciphering contents of intercepted file requested by Kindle

Hi, community!

With some help of the Kindle Store Proxy (especially this file), I was able to connect my Kindle Oasis (with 5.13.3) to a mitmproxy running on my Mac, deciphering even the HTTPS requests.

There were some interesting findings, such as the kindle POSTing to https://softwareupdates.amazon.com/software/inventory2 to check for updates.

While analyzing requests, I found one URL that was puzzling:

https://d18os95hu8sz6h.cloudfront.net/1/LATEST

The Kindle makes this request not very often, usually just right after startup.

The URL is also not user-specific (meaning that the Kindle doesn't POST any serial-related data) and I could download the file directly from my computer. I attached the file below to see if anyone can help decipher what the file is about. I also saved the file on the internet archive.

Edit #1: Add attachment. Ignore .txt extension at the end. Firefox seems to think that it's a .dms file.
