+Releases
+========
+
+v1.2.0 (2019-09-26)
+===================
+
+- Support extracting and matching against wrapped errors with `errors.As`
+ and `errors.Is`.
+
+
+v1.1.0 (2017-06-30)
+===================
+
+- Added an `Errors(error) []error` function to extract the underlying list of
+ errors for a multierr error.
+
+
+v1.0.0 (2017-05-31)
+===================
+
+No changes since v0.2.0. This release is committing to making no breaking
+changes to the current API in the 1.X series.
+
+
+v0.2.0 (2017-04-11)
+===================
+
+- Repeatedly appending to the same error is now faster due to fewer

+// Package multierr allows combining one or more errors together.
+//
+// Overview
+//
+// Errors can be combined with the use of the Combine function.
+//
+// multierr.Combine(
+// reader.Close(),
+// writer.Close(),
+// conn.Close(),
+// )
+//
+// If only two errors are being combined, the Append function may be used
+// instead.
+//
+// err = multierr.Append(reader.Close(), writer.Close())
+//
+// This makes it possible to record resource cleanup failures from deferred
+// blocks with the help of named return values.
+//
+// func sendRequest(req Request) (err error) {
+// conn, err := openConnection()
+// if err != nil {
+// return err
+// }
+// defer func() {
+// err = multierr.Append(err, conn.Close())
+// }()
+// // ...
+// }
+//
+// The underlying list of errors for a returned error object may be retrieved
+// with the Errors function.
+//
+// errors := multierr.Errors(err)
+// if len(errors) > 0 {
+// fmt.Println("The following errors occurred:")
+// }
+//
+// Advanced Usage
+//
+// Errors returned by Combine and Append MAY implement the following
+// interface.
+//
+// type errorGroup interface {
+// // Returns a slice containing the underlying list of errors.
+// //
+// // This slice MUST NOT be modified by the caller.
+// Errors() []error
+// }
+//
+// Note that if you need access to list of errors behind a multierr error, you
+// should prefer using the Errors function. That said, if you need cheap
+// read-only access to the underlying errors slice, you can attempt to cast
+// the error to this interface. You MUST handle the failure case gracefully
+// because errors returned by Combine and Append are not guaranteed to
+// implement this interface.
+//
+// var errors []error
+// group, ok := err.(errorGroup)
+// if ok {
+// errors = group.Errors()
+// } else {
+// errors = []error{err}
