Bumps github.com/fxamacker/cbor/v2 from 2.4.0 to 2.5.0.

Release notes

Sourced from github.com/fxamacker/cbor/v2's releases.

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.

Benchmarks provided by @​x448 for NewEncoder().Encode() optimized in PR 382.
