Post #70

It is finally time for a new release of python-telegram-bot, this time it's version 12.0.0b1! For the first time ever we have decided to do a beta release, since it has been so long since last release that we would like to test the impact before a final release. We do NOT recommend using this beta release in production. Major changes: - Context based callbacks - Persistence - PrefixHandler added (Handler overhaul) - Deprecation of RegexHandler and edited_messages, channel_post, etc. arguments (Filter overhaul) - Various ConversationHandler changes and fixes Since this is a beta release we have chosen to not list all changes here. See CHANGES.rst for a full list of the changes. This release has numerous backwards incompatible changes. See the wiki page at https://git.io/fxJuV for a detailed guide on how to migrate from version 11 to version 12. Since this is beta release it will not automatically be installed by pip. Instead you should do pip install python-telegram-bot==12.0.0b1 to explicitly request the new version.
