• Serializing numpy.ndarray with non-native endianness raises
  orjson.JSONEncodeError.

Changed

• Improve performance of serializing.

3.10.0

• Support serializing numpy.float16 (numpy.half).
• sdist uses metadata 2.3 instead of 2.1.
• Improve Windows PyPI builds.

3.9.15

Fixed

• Implement recursion limit of 1024 on orjson.loads().
• Use byte-exact read on str formatting SIMD path to avoid crash.

3.9.14

Fixed

• Fix crash serializing str introduced in 3.9.11.

Changed

• Build now depends on Rust 1.72 or later.

3.9.13

Fixed

• Serialization str escape uses only 128-bit SIMD.
• Fix compatibility with CPython 3.13 alpha 3.

Changed

• Publish musllinux_1_2 instead of musllinux_1_1 wheels.
• Serialization uses small integer optimization in CPython 3.12 or later.

3.9.12

Fixed

• Minimal musllinux_1_1 build due to sporadic CI failure.

Changed

• Update benchmarks in README.

3.9.11

Changed

• Improve performance of serializing. str is significantly faster. Documents
  using dict, list, and tuple are somewhat faster.
