Telegram v.4.6 is here! You can now set up your auto-download preferences with granular precision (find the new options in Settings > Data & Storage). For example, always download pictures from your mother on any connection, but only auto-download media from groups when you're on WiFi.

iOS users will enjoy the new option to swipe left on any message to quickly reply to it.

For everyone else, we've also added support for albums to Secret chats, full support for MTProto 2.0, and the option to only use p2p in calls with contacts (see Settings > Privacy & Security).

Link previews for Instagram posts and tweets with multiple photos will now show all the media as an album, like this:
