TinyCBOR release 0.5 (beta1) This is a beta release of TinyCBOR 0.5. Beta releases may have bugs and the API is still subject to change. TinyCBOR 0.5 contains numerous fixes and new API compared to 0.4. The main feature in this release is the CBOR Validation API, which can be used to perform a deeper validation of the contents than the simple syntax correctness that the main parser API provides. In particular, the API can be used to confirm that a given CBOR data type was encoded using either the Canonical Format (RFC 7049 section 3.9) and the Strict Mode (section 3.10). The API can also be used to confirm CBOR Text Strings carry properly-encoded UTF-8 text, a verification that the main parser does not perform. Starting in this release, the TINYCBOR_VERSION macro will be defined to the current version number. Other relevant changes include: - The list of known tags includes the tags used for CBOR Object Signing and Encryption (COSE - RFC 8152). - A new pair of functions cbor_value_get_{text,byte}_string_chunk can be used to obtain a direct pointer to the string data, without any memory allocation or memcpy (zero copy). - the functions taking FILE* are now conditional on a hosted C environment. They are not declared for freestanding C environments.
