  • Support coercing integral floats to ints when strict=False (#619).
  • Preserve leading _ when renaming fields to camel or pascal case (#620).
  • Support zero-copy decoding binary fields to a memoryview (#624).
  • Fix a bug when inheriting from the same Generic base class multiple times (#626).
  • Add an order option to all encoders for enforcing deterministic/sorted ordering when encoding. This can help provide a more consistent or human readable output (#627).

  • Ensure None may be explicitly passed to defstruct for module/namespace/bases (#445).
  • Support decoding datetime.datetime values from int/float values (interpreted as seconds since the Unix epoch) when strict=False (#452).
  • Support subclasses of collection types (list, dict, ...) as inputs to convert (#453).
  • Support str subclasses as keys in to_builtins and all protocol encode methods (#454).
  • Improved performance when JSON encoding decimal.Decimal values (#455).
  • Improved performance when JSON encoding int/float values (#458).
  • Improved performance when JSON encoding str values (#459).
  • Wrap errors in dec_hook with a ValidationError (#460).
  • Support decoding decimal.Decimal values from numeric values (#463)
  • Support encoding decimal.Decimal values as numeric values (#465).
  • Support converting decimal.Decimal values to float in convert (#466).
  • Preliminary support for CPython 3.12 beta releases (#467).
  • Support decoding integers that don't fit into an int64/uint64 (#469).
  • Add a new optional __post_init__ method for Struct types (#470).
  • Support decoding 0/1 into bool types when strict=False (#471).
  • Wrap errors raised in __post_init__/__attrs_post_init__ in a ValidationError when decoding (#472).

  • Deprecate msgspec.from_builtins in favor of msgspec.convert. The new convert function provides a superset of the functionality available in the old from_builtins function. See the converters docs for more information (#431).
  • Add a from_attributes argument to msgspec.convert for allowing conversion between object types with matching attribute names. One use case for this is converting ORM objects to Struct or dataclasses types (#419).
  • Support passing generic Mapping objects as inputs to msgspec.convert. These may be coerced to dict/Struct/dataclasses/attrs types (#427).
  • Add a new strict keyword argument to all decode functions, Decoder classes, as well as msgspec.convert. This defaults to True, setting it to false enables a wider set of coercion rules (e.g. coercing a str input to an int). See "Strict" vs "Lax" Mode for more information (#434).
  • Allow any of msgspec's supported types as inputs to msgspec.convert (#431, #418).
  • Passthrough input unchanged when coercing to typing.Any type in msgspec.convert (#435).
  • Support parametrizing Decoder types at runtime (#415).
  • Support encoding subclasses of UUID (#429).

  • Fix a reference counting bug introduced in 0.15.0 when decoding naive (no timezone) datetime/time objects in both the msgpack and json decoders (#409).
  • Work around an upstream bug in CPython to properly support Required/NotRequired in TypedDict when __future__.annotations is enabled (#410).
