This release refactors and hardens the streaming encoder by adding stricter checks for encoding CBOR indefinite-length data. Other changes include minor bugfixes, defensive checks, and more tests.
Projects that don't use CBOR indefinite-length data may also want to upgrade (summary of prior releases).
The stricter checks in the encoder prevent improper use of the library and bad inputs from producing malformed CBOR indefinite-length data that would be rejected by the decoder.
This release passed fuzz tests (billions of execs) and it is production quality.
