Post #101

We've just released v13.5. Thank you to everyone who contributed to this release. As usual, upgrade using pip install -U python-telegram-bot. This release brings full support for Bot API 5.2. ⚠️ There are a few things to mention about the API update: • The start_parameter argument of Bot.send_invoice and the corresponding shortcuts is now optional, so the order of parameters had to be changed. Make sure to update your method calls accordingly. • Service messages about non-bot users joining the chat will be soon removed from large groups. Telegram recommends using the chat_member update as a replacement. Luckily PTB already provides the ChatMemberHandler. To make things even more convenient, we added ChatMemberUpdated.difference(), which tells you exactly what changed for the chat member. Moreover, we added a neat example showcasing ChatMemberHandler and ChatMemberUpdated.difference(). • After the next Bot API update (Bot API 5.3) there will be a one-time change of the value of the field file_unique_id in objects of the type PhotoSize and of the fields small_file_unique_id and big_file_unique_id in objects of the type ChatPhoto. • ChatAction.{RECORD, UPLOAD}_AUDIO were deprecated in favor of ChatAction.{RECORD, UPLOAD}_VOICE Apart from the API changes, we also added the new Filters.forwarded_from filter. For the full list of changes and improvements, please see below.
