6.1.3

• Fixed the decoder registering 6-byte strings in the string reference namespace at indices 65536–4294967295 where the encoder does not, desynchronising the namespace and resolving later string references to the wrong value (#313; PR by @sahvx655-wq)
• Fixed the IPv4/IPv6 network decoders (tags 52 and 54) silently truncating an address byte string that is longer than the address size instead of rejecting it as malformed (#309; PR by @sahvx655-wq)
• Fixed quadratic decoding time for indefinite-length and large definite-length byte and text strings, caused by concatenating each chunk onto the accumulated result with + instead of building the result once (#316; PR by @sahvx655-wq)
• Fixed datetime_as_timestamp encoding whole-second datetimes before 1970 or after 2106 as floats instead of integers, because the timestamp was narrowed through an unsigned 32-bit integer (#317; PR by @sahvx655-wq)
• Fixed the encoder measuring text strings by code point count instead of UTF-8 byte length when deciding whether to add them to the string reference namespace, desynchronising it from the decoder (which counts bytes) and corrupting later string references for non-ASCII strings (#314; PR by @sahvx655-wq)
• Fixed the decoder rejecting scoped IPv6 addresses (tag 54) with a CBORDecodeError reading invalid types in input array; the encoder emits them as [address, null, zone id] but the decoder only handled the network and interface array forms, so a scoped ~ipaddress.IPv6Address could not be decoded back (#324; PR by @sahvx655-wq)
