Your signature is now ordinary text in the message you are writing: you see it, you can edit it, and you can delete it for a single message. It is no longer added invisibly when you press send, so what the composer shows is exactly what leaves. An imported HTML signature still reaches your recipient as HTML as long as you do not edit the block. Two new settings decide when it appears: whether replies and forwards get a signature (off by default), and whether it sits above or below the quoted message. Replies were reworked too. The attribution line is translated and shows a properly formatted date instead of a raw timestamp, the quoted message is cut at the sender's own signature so signatures stop piling up down a thread, and nested quotes keep their depth instead of collapsing into one flat level. Replying to all no longer writes to your own other addresses, and a forwarded message is carried in full, with translated header labels. Elsewhere: you can now swipe between the messages of a conversation, with an indicator showing where you are; snoozed messages have their own screen where you can cancel or reschedule them; a draft holding only a recipient is saved instead of being silently dropped; the outbox shows a counter when a message is waiting for the network; the offline banner clears on its own when the connection returns; leaving account settings offers to save; and seventeen texts that were still English only are now translated into every supported language. A message whose body had finished loading could stay hidden behind a spinner, most often an encrypted or signed one opened straight from the list, and it now always appears.
