• Fixed frozendict deriving its hash from its keys and its values as two independent sets, so that frozendicts holding the same keys and the same values all collided regardless of how the two were paired; since the decoder builds a frozendict for every map in an immutable position, a payload keyed by such maps decoded in quadratic time (#333; PR by @sahvx655-wq)
• Fixed the encoder not registering bytearray values in the string reference namespace, unlike bytes and str; since the decoder registers every byte string it reads, a single bytearray desynchronised the namespace and made subsequent string references resolve to the wrong value (#332; PR by @sahvx655-wq)
• Fixed the decoder silently accepting an indefinite-length map whose break marker arrives after a key with no value, dropping that trailing key and returning a truncated map instead of rejecting the ill-formed input (#331; PR by @sahvx655-wq)
• Fixed the decoder accepting a non-byte-string payload for a positive or negative bignum (tags 2 and 3). int.from_bytes() also accepts an array (or a map, whose keys it iterates), so a tag wrapping one of those was coerced into an integer instead of being rejected as malformed (#326; PR by @sahvx655-wq)
