v2.8.0 adds omitzero struct tag option, fixes and deprecates 3 functions, and bumps requirements to go 1.20+.

Many thanks to @liggitt for contributing the omitzero support!

The "omitzero" option omits zero values from encoding, matching stdlib encoding/json behavior.
When specified in the cbor tag, the option is always honored.
When specified in the json tag, the option is honored when building with Go 1.24+.

This release fixes 3 functions (when called directly by user apps) to use same error handling on bad input as cbor.Unmarshal():

  • RawTag.UnmarshalCBOR() (thanks @thomas-fossati for reporting this!)
  • ByteString.UnmarshalCBOR()
  • SimpleValue.UnmarshalCBOR()

This release also deprecates those 3 functions because they were initially created for internal use. Please use Unmarshal() or UnmarshalFirst() instead.

To preserve backward compatibility, the deprecated functions were added to fuzz tests and will not be removed in v2.x.

What's Changed

  • go: update go.mod and ci.yml to require go1.20 or newer (was go1.17) by @fxamacker in #626
  • Replace interface{} with any by @fxamacker in #627
  • Replace reflect.Ptr with reflect.Pointer by @fxamacker in #628
  • Replace reflect.PtrTo with reflect.PointerTo by @fxamacker in #629
  • Add omitzero support by @liggitt in #644
  • Update error handling in RawTag.UnmarshalCBOR(), etc. to match cbor.Unmarshal() by @fxamacker in #645
  • Optimize internal calls to UnmarshalCBOR() for ByteString, RawTag, SimpleValue by @fxamacker in #647

v2.7.1

v2.7.1 fixes 3 functions (when called directly by user apps) to use same error handling on bad inputs as cbor.Unmarshal():

  • ByteString.UnmarshalCBOR()
  • RawTag.UnmarshalCBOR()
  • SimpleValue.UnmarshalCBOR()

The above 3 fixed functions are deprecated because they were initially created for internal use. Please use Unmarshal() or UnmarshalFirst() instead.

To preserve backward compatibility, the deprecated functions were added to fuzz tests and will not be removed in v2.x.

Before Upgrading to v2.7.1

v2.8.0 is being fuzz tested and will be released later today. It adds support for omitzero struct tag option.

v2.7.1 is the last version to support go 1.17-1.19. v2.8.0 and newer releases will require go 1.20+.

What's Changed

  • Update error handling in RawTag.UnmarshalCBOR(), etc. to match cbor.Unmarshal() by @fxamacker in #636
  • Optimize internal calls to UnmarshalCBOR() by @fxamacker in #648

Special Thanks

Thanks @thomas-fossati for reporting the bug in RawTag.UnmarshalCBOR() when it is called directly by user apps providing bad input data!

What's Changed

Latest changes (among many) include cbor.MarshalToBuffer() and UserBufferEncMode interface to support user specified buffer (alternative to built-in buffer pool). This was going to be a release candidate but recent improvements (June 9, 2024) needs fuzzing, etc.

v2.5.0

This release adds important new features, optimizations, bug fixes, and 8 new contributors. Fuzz tests passed 5+ billion execs for CBOR encoding and decoding functions.

Notable changes are split into 3 categories.

⭐ Notable Changes to Review Before Upgrading

These new features and bug fixes were cherry-picked to highlight for review (for projects using older version).

  • PR 370: Add SimpleValue type to more fully support CBOR Simple Values, including values not assigned by IANA and...
  • PR 376: Add ByteString type to support CBOR maps with byte string keys because Go doesn't allow []byte as map keys and...
  • PR 379: Make Decoder.Decode() return io.ErrUnexpectedEOF instead of io.EOF on EOF if current CBOR data item is incomplete.
  • PR 380: Make Unmarshal() and Valid() return cbor.ExtraneousDataError (instead of ignoring extraneous data if any remain).
  • PR 387: Retry in Decoder if io.Reader's Read() returns 0 bytes read with nil error. Add tests to get 100% code coverage for stream.go.

⭐ More Notable Changes

  • PR 342: Add DecOptions.UTF8 to decode invalid UTF-8. Default is unchanged (reject invalid UTF-8 and return error).
  • PR 355 Allow MaxNestedLevels setting to be configured up to 65535.
  • PR 352, 377: Add EncOptions.NilContainersMode to encode nil Go maps and slices as either CBOR nil (default) or empty container.
  • PR 381: Add Decoder.Skip() to skip CBOR data item in CBOR Sequences (RFC 8742).
  • PR 386 Add functions for Extended Diagnostic Notation (RFC 8610 Appendix G).
  • PR 398 Add UnmarshalFirst() to decode CBOR data item and also return remaining bytes.
  • PR 400 Deprecate Valid and add Wellformed to replace it.
  • PR 402 Add UnmarshalFirst() to DecMode interface.
  • PR 412 Add Decoder.Buffered to return remaining data in buffer.

🚀 Notable Changes Affecting Speed or Memory Use

  • PR 335: Reuse underlying array if RawMessage has sufficient capacity.
  • PR 382: Return buffer to pool in Encode(). It adds a bit of overhead to Encode() but NewEncoder().Encode() is faster and uses less memory.

Benchmark comparison for PR 382 shows significant improvement in speed and memory use.
