Another major Telegram update is out now after having been finally approved by Apple. It is packed with unique features that expand the boundaries of what a messaging app can do. Check them out.
This new version of Telegram also contains an important upgrade that will allow our apps to work without interruption. Until now, Telegram used 32-bit values for the identifiers of users and channels. Due to its fast growth, Telegram had been quickly approaching the maximum number of 32-bit IDs, which is about 2.1 billion.
That's why for the last 12 months we've been rebuilding nearly all of our apps, storage architecture and scripts to migrate to the 64-bit range (so we can expand to other galaxies without any issues). The latest update is critical to let new users sign up for Telegram and existing users keep creating channels and groups.
After updating Telegram, some users may have to wait a minute or two for their chat database to be optimized for 64 bits. We are also investigating a few reports from the Android users that are facing connection issues after updating the app. We are fixing this, but if you don't want to wait, logging out and in again will help.
