Auto-Delete, Widgets, Expiring Invite Links and More

You can now set an auto-delete timer in any chat, which will erase messages for all participants 24 hours or 7 days after they are sent.

New home screen widgets for iOS and Android let you preview messages and instantly open chats.

Group and channel admins can create additional invite links with a limited duration, number of uses, or both.

Groups approaching the limit of 200k members can now convert to Broadcast Groups that allow unlimited members.
