v0.9.0: errors 0.9.0

Compare Source

errors 0.9.0 is a preparation release for a 1.0 final release. Also we were working on removing support for Go 1.8, 1.9 and 1.10 and earlier, and become compatible this package with new way of errors on Go 1.13.

We tried to move into runtime.CallerFrames but this was not possible, you can show the explanation here: Issue 188.

The motivation for do the backward compatible this package with Go 1.13 is that you can migrate the easy way for this to the new way.

Now you could use the methods, Is and As, and the Unwrap() interface like on the standard library.

The method Cause is now compatible with fmt.Errorf("%w", err) and with the Unwrap() interface.

On the same way the methods related with wrapping on this package now are compatible with Cause and Unwrap() interface.

• Reduce allocations in Stacktrace.Format
• Add Support to Go 1.13. Thanks @​jayschwa, @​Sherlock-Holo and @​puellanivis.
