v1.37.1

• Accidentally send a message to the wrong chat? Take backs are now permitted. When deleting a recently sent message, you now have the option to Delete for Everyone in the chat.
• Picture-in-picture support within the app keeps your Signal calls in focus even if you focus on another conversation. It isn't multitasking if they still have your undivided attention.
• You can now see a preview of yourself before you start a video call to make sure you look as good as you feel.
• Improved message reactions, including the ability to customize skin tones.
• Now you can retrieve link previews directly from any website for messages you send. If you don’t want to send link previews, you can disable them from your primary device.
• Pin your favorite chats at the very top so the talk never stops.
• Corrected an issue that caused some messages to show up out of order.
• Improved the contributing documentation (fixed by Oren Magen)
• Added a missing validity check for the proxy URL (fixed by iomintz)
