## Version 3 breaking changes
If you have used version 2, there are a couple of breaking changes in version 3
that you should be aware of. If you are new to `cxxopts` you can skip this
section.
The parser no longer modifies its arguments, so you can pass a const `argc` and
`argv` and expect them not to be changed.
The `ParseResult` object no longer depends on the parser. So it can be returned
from a scope outside the parser and still work. Now that the inputs are not
modified, `ParseResult` stores a list of the unmatched arguments. These are
retrieved like follows:
```cpp
auto result = options.parse(argc, argv);
result.unmatched(); // get the unmatched arguments
```

## Unrecognised arguments
You can allow unrecognised arguments to be skipped. This applies to both
positional arguments that are not parsed into another option, and `--`
arguments that do not match an argument that you specify. This is done by
calling:
```cpp
options.allow_unrecognised_options();
```
and in the result object they are retrieved with:
```cpp
result.unmatched()
