The Erlang VM only allows a limited set of expressions as guards:

• comparison operators (==, !=, ===, !==, >, <, <=, >=);
• boolean operators (and, or) and negation operators (not, !);
• arithmetic operators (+, -, *, /);
• <> and ++ as long as the left side is a literal;
• the in operator;
• all the following type check functions:
  • is_atom/1

• is_binary/1

If you want a run-down of the 1.3 changes and the design decisions behind those changes, check out the LonestarElixir Phoenix 1.3 keynote: https://www.youtube.com/watch?v=tMO28ar0lW8

To use the new phx.new project generator, you can install the archive with the following command:

$ mix archive.install https://github.com/phoenixframework/archives/raw/master/phx_new.ez

Bump your phoenix dep

Phoenix v1.3.0 is a backwards compatible release with v1.2.x. To upgrade your existing 1.2.x project, simply bump your phoenix dependency in mix.exs:

class HoverException(Exception):

        params = {"username": username, "password": password}
        r = requests.post("https://www.hover.com/api/login", params=params)
