Release Notes

v0.9.1

Compare Source

pkg/errors 0.9.1 is a bug fix release for errors 0.9.0. This restore the previous behaviour on Cause method, this behaviour was changed on the PR: #​215 and many breaking changes was produced by that.

v0.9.0

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.

Improvements

• .travis.yml Now use make file.
• reduce allocations when printing stack traces. Thanks @​cstockton
• Reduce allocations in Stacktrace.Format
• Add Support to Go 1.13. Thanks @​jayschwa, @​Sherlock-Holo and @​puellanivis.
• Add json.Marshaler support to the Frame type. Thanks @​flimzy

Bugs fixed

• .travis.yml Adjust Go versions. Thanks @​komuw, @​aperezg
• minor fix in an example to print Stack Trace. Thanks @​bep.
• Remove not necessary code.
• Clean up documentation. Thanks @​seh.

v0.8.1

Compare Source

pkg/errors 0.8.1 is a bug fix release for errors 0.8.0. It will be the last version to support Go 1.8 and below. pkg/errors 0.9 and above will require Go 1.9 for the new runtime.CallersFrames API.

pkg/errors 0.8.1 also adds one new feature, errors.WithMessagef. Ideally this would be held over til 0.9, but that complicates the switch to runtime.CallersFrames.

Improvements

• Added errors.WithMessagef. Thanks @​chemicL.
