v2.7.0
v2.7.0 (June 23, 2024)
v2.7.0 adds features and improvements that help large projects (e.g. Kubernetes) use CBOR as an alternative to JSON and Protocol Buffers. Other improvements include speedups, improved memory use, bug fixes, decoding/encoding options, etc. Passed 5+ billion execs fuzzing.
Special thanks to @benluddy for contributing features, optimizations, improvements, bug fixes, and discussions! 👍

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.

v2.5.0-beta5
v2.5.0-beta5 is fuzz tested and production quality, but docs need to be updated before releasing v2.5.0.
IMPORTANT: Please view these release notes (esp. v2.5.0-beta) before upgrading from v2.4 or earlier:
- v2.5.0-beta4 - Bugfix for
Diagnose
to return io.EOF
on empty data.
- v2.5.0-beta3 - Add functions:
Diagnose
, DiagnoseFirst
, UnmarshalFirst
, Wellformed
.
- v2.5.0-beta2 - Bugfix to retry in
Decoder
if io.Reader
's Read()
returns 0 bytes read with nil error.
- v2.5.0-beta - Notable improvements, optimizations, bugfixes, and 8 new contributors!
What's Changed since v2.5.0-beta4
Full Changelog: v2.5.0-beta4...v2.5.0-beta5
v2.5.0-beta4
Features already present in v2.4 are release quality. Newly added functions require more fuzzing and docs.
IMPORTANT: Please view these release notes (esp. v2.5.0-beta) before upgrading from v2.4:
- v2.5.0-beta3 - Add
Diagnose()
, DiagnoseFirst()
, UnmarshalFirst()
, Wellformed()
.
- v2.5.0-beta2 - Bugfix and release notes include benchmark comparison of v2.5.0-beta2 vs v2.4.0.
- v2.5.0-beta - Notable improvements, optimizations, bugfixes, and 8 new contributors!
What's Changed Since v2.5.0-beta3
- Bump safer-golangci-lint to 1.52.2 by @x448 in #408
- Fix
Diagnose()
to return io.EOF
error on empty data by @fxamacker in #410
- Update README.md for cbor v2.5.0-beta4 by @fxamacker in #411
Full Changelog: v2.5.0-beta3...v2.5.0-beta4
v2.5.0-beta3
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.
What's Changed (since v2.5.0-beta2)
- Deprecate Valid() and add Wellformed() to replace it by @fxamacker in #400
- Add UnmarshalFirst by @immesys in #398
- Add UnmarshalFirst to DecMode interface by @fxamacker in #402
- Add functions for Extended Diagnostic Notation (RFC 8610 Appendix G) by @zensh in #386
- Add more tests for Diagnose and DiagnoseFirst by @fxamacker in #405

Special Thanks
Thank you @immesys, @zensh, and @x448 for your contributions!

v2.5.0-beta2
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).
What's Changed Since v2.5.0-beta
- Retry in Decoder if io.Reader's Read() returns 0 bytes read with nil error by @fxamacker in #387
- This PR also added more tests so we have 100% coverage for stream.go.
- Update fxamacker_cbor_banner.png for v2.5 by @x448 in #383
- bump safer-golangci-lint.yml to 1.51.1 by @x448 in #389
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.
