(I edited my previous post slightly with more information.)
I also wrote a lot of this information months ago in these two Reddit threads:
Kindle Formatting Woes
What are the pros and cons of ePub vs MOBI?

There's 3 main types of Kindle files:
- MOBI (KF7)
- Kindle 1+2 and DX.
- Calibre calls this AZW.
- KF8
- Kindle 3+
- Calibre calls this AZW3.
- KFX
- (I believe this is also Kindle 3+.)
- This is their most recent format. You can tell when the book says it has "Enhanced Typesetting".
See the topics above for some more detailed explanation.
To really simplify things:
- KF7 is some crippled step-child.
- KF8 is "pretty much an EPUB".
- And KFX, while looking nice on the outside, is an absolute disgusting thing underneath the surface.
But if it works in EPUB, it probably works the same in KF8 + KFX.
An issue with Amazon's ecosystem is, you'll always have that KF7 deadweight hanging on your leg:
If you work in simple Fiction that's purely text, you're probably fine.
But if you're working on Non-Fiction, or doing more complex things (like Poetry/Formulas)... that's where you begin to run into issues on the ol' KF7 edge-cases, and have to code MOBI-specific fallbacks.
