Stops the sync window from deleting the mail it has just downloaded. A folder holding older messages could drop back to its two newest ones a moment after showing them all; it now keeps what the server just sent, and never empties a folder below the number of messages your "Messages to sync" setting names. A message sent in 8 bits with a character set other than UTF-8 shows its accented and non-Latin characters instead of replacement marks, a file attached to such a message is saved with its bytes intact, and the sender's address on it is read correctly rather than stored mangled; base64 and quoted-printable, which is most mail, were never affected. The move-to-folder picker now shows where a folder lives, so two folders both called "Done" are no longer the same row, and a filter rule that files mail into a folder inside another one now names that folder in full. Sorting by date, subject, sender or unread really sorts by that and nothing else, with a new "Starred first" entry for anyone who wants starred mail kept on top, and advanced search gained a "Starred only" switch so starred mail can be gathered from the whole account rather than only spotted where it happens to sit. A message from a past year now shows that year, as a short numeric date in your language's own order, so an August 2019 mail can no longer be mistaken for an August 2026 one. The star is called a star everywhere now, rather than a flag in one place and a favourite in another. The link confirmation gained a Copy button, and tapping something that leaves the app now does it once even when the tap registers twice, so a contact or a calendar event is no longer created in duplicate. When a push connection dies without the service dying with it, the 30 minute catch-up now checks that account instead of standing down, and with several accounts watched, mail waiting on an account you are not looking at no longer loses its notification when you open the app. A search that is still running says "at least" rather than announcing a total, and never claims there are no results when it stopped before the end.
