0.4.3 (2018-01-14)

  • Deserialize from bytes and bytearray instances, ensuring they contain valid UTF-8 data
  • Speed up parsing of floating point numbers, avoiding intermediary conversion to a Python string (PR #94)

  • Fix precision handling of DM_UNIX_TIME timestamps

0.4.1 (2018-01-08)

  • Fix memory leaks in Decoder() and Encoder() classes, related to bad handling of PyObject_GetAttr() result value
  • Fix compatibility with Python 3.7a

0.4.0 (2018-01-05)

  • Implemented the streaming interface, see load() and dump() (issue #80)

    Backward incompatibility: now the flags arguments on all the functions are keyword only, to mimic stdlib's json style

0.3.1 (2017-12-20)

  • Fix Travis CI recipe to accomodate MacOS

0.3.0 (2017-12-20)

  • Fix compilation on MacOS (issue #78)

  • New parse_mode option, implementing relaxed JSON syntax (issue #73)
  • New Encoder and Decoder, implementing a class-based interface
  • New Validator, exposing the underlying JSON schema validation (issue #71)

  • Fix Powershell wheel upload script in appveyor configuration

0.1.0b1 (2017-08-12)

  • Compilable with somewhat old g++ (issue #69)

  • New keyword argument number_mode to use underlying C library numbers
  • Binary wheels for GNU/Linux and Windows on PyPI (one would hope: this is the reason for the beta1 release)
