*Sourced from [failure's changelog](https://github.com/rust-lang-nursery/failure/blob/master/RELEASES.md).*

> # Version 0.1.4
> 
> - Improved error reporting of the derive feature

>   that prevented backtrace from improving an upstream API.
> - Changed the bounds on std error compat conversions through the From trait
>   to take Sync and Send into account.
