Signal Desktop: v5.4.0-beta.2 Release

• Introducing screen sharing: Now you can present your computer’s entire screen or a specific window during video calls. Just click the start presenting button while in a video call to get started. • Become a conversation artist. Use the new color selector to turn every chat into a masterpiece. • Lay out the welcome mat by adding a description to your groups. We know some things are difficult to put into words, so maybe start with an emoji 👋. • Letting go can be hard, but our new custom disappearing timer can help you find a little more time to process those fleeting messages before they're gone forever. • A new setting lets you specify a default disappearing message timer for new chats and groups that you start.
