2023. Send to Kindle is losing MOBI support
In the kind of language that might make even a Vogon pause and scratch its head in bemusement, Amazon has commenced the herculean task of reminding its customers—with a most ominous "Final Reminder"—that the beloved but arcane MOBI file format (.AZW, .MOBI, .PRC) will no longer be welcome in the sprawling universe of their Send to Kindle service as of later this Earth-year. This wasn’t entirely unanticipated; after all, Amazon did declare, with as much solemnity as one can muster while talking about file formats, that MOBI support would fade into the mists of "late 2022." Naturally, this timetable wandered a bit, lurching toward "early 2023," then whistling jauntily along until an unexpected September 2023. Now, however, with all the vigor of an advanced bureaucracy, Amazon is—probably—determined to "phase out support" for the ancient MOBI files starting November 1st, 2023, when the proverbial curtain finally descends on a format older than most people’s email passwords.
