[PYTHON] Before I knew it, I couldn't use hyphens in the client id of GAE's Channel API.

As the title says. Hyphens were also available until early July 2013. As of August 5, 2013, I can issue a token and open it with a hyphen, but push (channel.send_message) does not work. You can give 100 steps and no hyphen, but if so, please issue a token and throw an error. I don't understand the meaning too much. Or rather, there aren't enough errors around the channel api. If you miss channel.send_message, please throw an error. Be careful if you are generating a client id with uuid.uuid4 (). Google please give me 80,000 yen to write this article.
