## Unreleased
### Added
- Add UnwrapFrame function to extract a single frame from an error.
- Add `UnwrapFrame` function to extract a single frame from an error.
You can use this to implement your own trace formatting logic.
- Support extracting trace frames from custom errors.
Any error value that implements `TracePC() uintptr` will now
contribute to the trace.
- Add `GetCaller` function for error helpers to annotate wrapped errors with
their caller information instead of the helper. Example:

```go
//go:noinline
func Wrapf(err error, msg string, args ...any) {
caller := errtrace.GetCaller()
err := ...
return caller.Wrap(err)
}
```

- cmd/errtrace:
Add `-no-wrapn` option to disable wrapping with generic `WrapN` functions.
This is only useful for toolexec mode due to tooling limitations.
