io-console has changed between 2.1.0 and 2.1.1  so it should be reflected in its version number.

This is still/again issue for Ruby 2.2. There are changes in io-console but its version does not reflect them. Could you please make the io-console versioning reliable and useful? Thanks
BTW this is concern for BigDecimal as well ...
