My findings so far, in no particular order:
- This is indeed a different FW version. What is pretty nasty from Amazon's part is that by making it available at the same URL as the old version, they seem to want to make the original 5.4.2 firmware disappear.
- at least when directly updated from a jailbroken 5.4.2, the jailbreak survives.
- the jailbreak also seems to work for this version.
- this version cannot easily be downgraded to the original 5.4.2. This may be a side effect of Amazon simply having replaced the 5.4.2 .bin, or there could be another reason. I don't know.
