Release Notes
fxamacker/cbor
v2.4.0
This release adds two user-requested features to the decoder. It passed 3+ billion execs fuzzing before being tagged.
What's Changed
- Add option to specify default Go map type when decoding CBOR map into interface{} by @fxamacker in https://github.com/fxamacker/cbor/pull/316
- Add support for decoding registered CBOR tag to interface type by @fxamacker in https://github.com/fxamacker/cbor/pull/308
- Update CBOR docs for v2.4.0 by @x448 in https://github.com/fxamacker/cbor/pull/318
Special Thanks
- @lukseven for opening issue #303 and proposing a solution
- @Gui-Yom for issue #301

v2.3.1
IMPORTANT:
- This release fixes an important typo in README and omission in CONTRIBUTING.
- No changes to code outside _test.go files.
- Changes to non-test files are limited to comments.
- Next release (v2.4.0) started fuzz testing and is expected to be tagged within 1-2 weeks.
Changes to v2.3.1 include:
- Fix typo in docs (example code snippet) that can cause bugs. Thanks @herrjemand!
- Update CONTRIBUTING to mention signing requirements. Thanks @lukseven and @x448!
- Update README. Thanks @x448 and @rumpelsepp!
- Update ci.yml to use Go 1.17.x. Thanks @x448!
- Add Revive as a lint checker.
- Cleanup lint messages in _test.go files
- Cleanup lint messages in non-test files if the changes are limited to comments (no actual coding changes).

v2.3.0
Upgrading is recommended: v2.3.0 has bug fixes, is faster, and passed 1+ billion execs fuzzing.
⭐ Features and Improvements
- Add built-in support for big.Int (#209)

🚀 Performance
fxamacker/cbor 2.3.0 is faster than 2.2.0 by up to 14% (using CWT and COSE example data from RFCs).

🧪 Tests and Fuzzing
- Code coverage remains above 98%.
- Coverage-guided fuzzing reached 1+ billion execs ~2 days after v2.3.0 release.
👍 Special Thanks
- Special thanks to @kostko, @turbolent, @x448, @yawning and others for reporting bugs, providing feedback, and more.
⛈ ️ Winter Storm Uri Displaced Me (still at a hotel 3+ months later)
- As of May 30, I'm still displaced due to Winter Storm Uri started causing damage on February 16. Fire sprinklers started leaking, pipes shattered in the ceilings, and water outage lasted 2+ weeks.
