v3.0.0

This release allows reading the password even if there is no \n at the end of the input. Thanks @longshorej for this improvement. Here was the justification behind the change:

In general, GNU readline will return the input it has read when reaching EOF. It seems to me that rpassword's current behavior in this regard is not conventional.

This a breaking change so the version has been bumped up to 3.0.0 on crates.io.

Feel free to open an issue if you need any help.
