更新日志

版本 5.5.0

• This update improves the onboarding experience for new Signal users. If you’ve already been using Signal for a long time, feel free to invite a new friend and then ask them to tell you all about it.

• We made message processing significantly faster, so you can fly through your message backlog after your flight lands, or quickly power through what you missed while you were looking for a power outlet.

• We filled in the blanks with bug fixes for stickers and delivery receipt checkmarks that weren’t always appearing for some users.

版本 3.13.2

• You can now send and receive voice and video calls from your linked iPad.

• Sometimes your emojions just can’t be contained, so we’ve removed the message bubble on short emoji only messages.

• If boundless emoji aren’t enough, you can now send memoji and other stickers directly via the keyboard.

• Not everyone has earned the right to live in your address book, but that doesn’t mean they don’t deserve to hear from you. You’ll now see all approved contacts as options when starting a new conversation or editing a group.

• Incoming calls will no longer ring your device when you haven’t approved the caller. They’ll be notified their call was rejected because you haven’t accepted their request.

• Now you can put a pin in PINs and disable them completely. This option is for advanced users who don't want to lose their ability to lose everything.

版本 3.12.4

• The badge count on the app icon now excludes new messages in muted threads and also gets updated when a thread is marked as unread. In other words, numbers after a mute point are a moot point, and you'll see a red "1" when you unread someone.

• Even though the changes are completely unrelated to fast money, the cache performance improvements in this release still help the app feel like a million bucks.

• In ancient times, you'd have to use stones or weights to keep the paper from curling up past where you wanted it to be, but these are modern times so we just added a feature that automatically maintains your scroll position.

• We updated the message retry user interface so it's easy to try again without trying your patience.

版本 3.11.1

• Additional optimizations to speed up message delivery and the overall feel of the app.

• Jump for joy instead of jumping for no reason. We fixed several bugs related to scrolling performance and behavior.

• What was it like when images in incoming photo albums were occasionally shown in the wrong sequence? What emotions did you experience when the badge count display sometimes didn't update? These questions are now both historical *and* rhetorical, because we fixed both of those bugs too.
