We received a lot of valuable feedback on our first release of eris and recently released v0.2.0 with improvements (changelog:
https://github.com/rotisserie/eris/blob/master/CHANGELOG.md).
* Improved the stack trace for both local and global errors
* Streamlined error formatting (it's now a single call: ToString or ToJSON)
* Completely rewrote our documentation and added direct comparisons to pkg/errors
* Added more examples (https://godoc.org/github.com/rotisserie/eris#pkg-examples)
* Added Sentry support
* Bug fixes
At this point, we're looking for more users and feedback so we can continue improving it!
