v8.17.0-beta.1

• Group admins can now delete recently sent messages in a group chat. If someone accidentally posts a spoiler in your Book Club group and then walks away from their phone, a group admin can delete it to keep the plot twist intact. You can easily see when a message was deleted and who removed it, just like the existing "Delete for Everyone" feature.
• We also increased the maximum number of pinned chats from 4 to 10, so you can show 6 more people how much you love what they have to say.
