feature parity with the upstream Telegram API (except for keyboards and
inlines), including the new features in the Bot API 2.0 and 2.1 updates,
such as moderating group chats or editing messages.

Performance are improved, with a faster updates fetching process, and a
bug was fixed in this release. There are also a few deprecations to keep
the API clean.  All the deprecated features in this release will be

ones.
