Introduce compiler option 'nowarn_deprecated_type'
The deprecation of the built-in types dict/0 and so on had as side-effect that it was impossible to switch to dict:dict/2 and so on without getting warnings either in the the previous release (R16B) or the current one (17.0). By including the attribute -compile(nowarn_deprecated_type). in an Erlang source file warnings about deprecated types can be avoided in 17.0. The option can also be given as a compiler flag: erlc +nowarn_deprecated_type file.erl
