Version 4.4.

- You can set a Global Auto-Delete Timer
for all new chats and groups you create.
- New messages will be deleted after 1 day, week, month,
or a custom duration you choose.
- The new menu in Settings > Privacy & Security > Auto-Delete Messages
also lets you set up Auto-Delete for any of your existing chats faster.
- Admins of groups with 100+ members can organize discussions
into separate topics.
- Topics now have a two-column layout
that keeps recent chats easily accessible as you browse topics.
- Previews of topic messages in the chat list work like a button,
click to jump to the last updated topic.
- Up to 5 topics can be pinned to the top of the list.
- Each topic now supports multiple pinned messages.
- The View as Messages mode now shows
which topic each message belongs to.
- Badge counters for topics you never opened
will have a lighter, less distracting color.
- A new General topic is now included by default,
containing service messages and the earlier message history from the
group.
- Admins can rename the General topic.
- Large groups can enable Aggressive Filtering in Manage Group
> Administrators to remove more spam with automated algorithms.
- Admins help improve filtering
by reporting any false positives in Recent Actions.
