Telegram Passport (:pr:`1174`):

- Add full support for telegram passport.
- New types: PassportData, PassportFile, EncryptedPassportElement, EncryptedCredentials, PassportElementError, PassportElementErrorDataField, PassportElementErrorFrontSide, PassportElementErrorReverseSide, PassportElementErrorSelfie, PassportElementErrorFile and PassportElementErrorFiles.
- New bot method: set_passport_data_errors
- New filter: Filters.passport_data
- Field passport_data field on Message
- PassportData can be easily decrypted.
- PassportFiles are automatically decrypted if originating from decrypted PassportData.
- See new passportbot.py example for details on how to use, or go to `our telegram passport wiki page`_ for more info
- NOTE: Passport decryption requires new dependency `cryptography`.

Inputfile rework (:pr:`1184`):

- Change how Inputfile is handled internally
- This allows support for specifying the thumbnails of photos and videos using the thumb= argument in the different send\_ methods.
- Also allows Bot.send_media_group to actually finally send more than one media.
- Add thumb to Audio, Video and Videonote
- Add Bot.edit_message_media together with InputMediaAnimation, InputMediaAudio, and inputMediaDocument.

Other Bot API 4.0 changes:

- Add forusquare_type to Venue, InlineQueryResultVenue, InputVenueMessageContent, and Bot.send_venue. (:pr:`1170`)
- Add vCard support by adding vcard field to Contact, InlineQueryResultContact, InputContactMessageContent, and Bot.send_contact. (:pr:`1166`)
- Support new message entities: CASHTAG and PHONE_NUMBER. (:pr:`1179`)
- Cashtag seems to be things like `$USD` and `$GBP`, but it seems telegram doesn't currently send them to bots.
- Phone number also seems to have limited support for now
- Add Bot.send_animation, add width, height, and duration to Animation, and add Filters.animation. (:pr:`1172`)
