I thought the response was a bad thing, but if it just means we’re finally accepting epub as a common default that’s pretty great, right?

Does Amazon still strip metadata and cover art from user-provided epubs? If they're still intentionally gimping the implementation, IMO it's a step backwards

Not sure about metadata, but cover art persists through the email-to-kindle process at least.

Finally! Amazon should have done this long ago. ePub v3 supports everything MOBI does and it has really extensive support across platforms. This is HUGE for people with a big eBook collection.

Note that the Kindle devices themselves still do not support ePub files. (EDIT: as of the last time I checked a month or two ago, but maybe this has changed?)

Previously, you could send a MOBI file to your Kindle email address, and it would be delivered to your Kindle. Now, you have to send them an ePub file, and Amazon will convert it to an AZW3 file (which is structurally very similar to MOBI) and send that to your Kindle.

If you have an ePub file and you want to read it on your Kindle without going through Amazon's servers, you have to convert it to AZW3 (or MOBI) yourself, either using Amazon's Kindle Previewer GUI software (only available for Windows/Mac) or by using a third-party tool like Calibre.

Amazon chose MOBL because it was compatible with the PRC format the old Palm Pilots used. The Palm Pilot was the original eBook reader.

yup, and the original app to read these was MobiPocket reader. Curiously, the pdb wrapper is completely pointless on all non-palmOS platforms, but since it only adds a negligibly-small header (0x4e + (dataSize / 0xff00) * 8) bytes, nobody cared and it allowed using all original tools

It does on first web sync after the ebook is transferred. It can be fixed (by transferring again) and then it won’t be removed on subsequent sync.

I'm extremely confused about this. I have an older Kindle Paperwhite (PW 3/ 7th gen I think?) and when I used the 'email sent' feature I got that mail about dropping mobi support in favor of epub, but when sending an actual epub I got an error for sending a wrong file, ostensibly because the Kindle only supports mobi.

Are they going to ship a software update? Would be a shame if that service doesn't work any more in the future.

This is a welcome move, but I keep trying to figure out how this is going to effect Libby users (which is probably 80% of my kindle usage these day) and I can't find any info at all. Does anyone have any idea?

This particular page is only talking about a change to Microsoft's ebook store.

On Amazon's side, they've been updating their docs to talk about how MOBI is "deprecated", but the only actual change announced is that MOBI support has been removed from the "Send to Kindle" (via email) feature. So if you're not using that, you should be unaffected.
