This release adds 4 new functions: UnmarshalFirst, Diagnose, DiagnoseFirst, and Wellformed. In addition Valid function is deprecated (use Wellformed instead).
UnmarshalFirst decodes first CBOR data item and returns remaining bytes. This is useful for CBOR Sequences (RFC 8742) and also because Unmarshal was fixed in v2.5.0-beta to return ExtraneousDataError if there are remaining bytes.
Diagnose and DiagnoseFirst returns human-readable Extended Diagnostic Notation (RFC 8610 Appendix G) for the given CBOR encoding. These are useful for debugging and allows more user-friendly error logging.
There are fewer changes in v2.5.0-beta2 compared to v2.5.0-beta. Speed and memory improvements since v2.4.0 are from v2.5.0-beta. Tests cover 98.5% and reached 100% coverage for stream.go (e.g. Decoder using the provided io.Reader).
Go language recommends that Read implementations for io.Reader avoid returning 0 with nil error. It also recommends that callers receiving 0 and nil from Read should treat it as if nothing happened. This edge case is handled properly now.
@x448 shared benchmarks comparison of v2.4.0 vs v2.5.0-beta2. Performance improvements are from v2.5.0-beta.
