5.0.0 - ?

This version comes with a complete rewrite of nom internals to use functions as a base
for parsers, instead of macros. Macros have been updated to use functions under
the hood, so that most existing parsers will work directly or require minimal changes.

The CompleteByteSlice and CompleteStr input types were removed. To get different
behaviour related to streaming or complete input, there are different versions of some
parsers in different submodules, like nom::character::streaming::alpha0 and
nom::character::complete::alpha0.

The verbose-errors feature is gone, now the error type is decided through a generic
bound. To get equivalent behaviour to verbose-errors, check out nom::error::VerboseError
