Sorry, didn't wanna lash on you guys like that, but the truth of the matter is that there must be some sort of communication when you guys are dropping obsolete APIs, so that it doesn't come as a surprise. Luckily it was just a URL replacement, and my app works again
We announced we'll drop support of login/password access to the API within ~1 year.
We'll soon add a system that will every month list all the people using that method and send them an email introducing the API key identification system, to allow for a smooth migration.
