Telethon 0.13.4

More bug fixes and enhancements

on Python PyPI

New stuff:

• TelegramClient now exposes a .is_connected() method.
• Initial authorization on a new data center will retry up to 5 times by default.
• Errors that couldn't be handled on the background thread will be raised on the next call to .invoke() or updates.poll().

Bugs fixed:

• Now you should be able to sign in even if you have process_updates=True and no previous session.
• Some errors and methods are documented a bit clearer.
• .send_message() could randomly fail, as the returned type was not expected.

Things that should reduce the amount of crashes:

• TimeoutError is now ignored, since the request will be retried up to 5 times by default.
• "-404" errors (BrokenAuthKeyError's) are now detected when first connecting to a new data center.
• BufferError is handled more gracefully, in the same way as InvalidCheckSumError's.
• Attempt at fixing some "NoneType has no attribute…" errors (with the .sender).

Other internal changes:

• Calling GetConfigRequest is now made less often.
• The initial_query parameter from .connect() is gone, as it's not needed anymore.
• Renamed all_tlobjects.layer to all_tlobjects.LAYER (since it's a constant).
• The message from BufferError is now more useful.
