Release 0.0.16

• Replace zmij (Rust) with xjb64, an extremely fast float-to-string algorithm, which is 10%+ faster than zmij and compliant with Python json. Thanks the author of xjb64 @xjb714 for Python porting guidance.
• Other internal refactors.

Release 0.0.14

This is a performance improvement release.

#27 Refactor encoding call args for performance, gives a 7%~60% performance improvement on fast paths
#28 :

• Replace Dragonbox with Żmij (Rust implementation), a faster implementation of writing floats
• Some internal refactors that improve performance

Breaking changes:

Żmij (Rust implementation) output fixed-point notations instead of scientific notations when possible. Before this release ssrJSON (using Dragonbox) outputs a scientific notation.

Release 0.0.13

Support free-threading (Python >= 3.14). Distribute wheel for cp314t (not lock-free).
Bugfix: decoding ref count leak when repeated key appears in the string.

Release 0.0.12

This is a bug fix version.

• Fix memory access violation when calling loads with object_hook in multi-threads. The problem will occur when GIL is released in the hook function in version 0.0.11.

Breaking change:

• Linux: GLIBC version requirement is updated from 2.17 to 2.34. If you use glibc below 2.34, we recommend you to build ssrJSON from source.

Release 0.0.11

Implement object_hook functionality, by @Nambers #23
And other internal refactors (function rename, code cleanup)

Release 0.0.10

• Fix bug that wheels on PyPI for MacOS are not working
• Now you can use SSRJSON_WRITE_UTF8_CACHE env variable to control whether to write cache when importing ssrJSON the first time
• Keys in the output of get_current_features become snake_case now (breaking change)

Release 0.0.9

This is a bugfix version.

Changes:

• For short strings (len < 6), writing cache is disabled even if requested.

Bug fixes:

• Fix raising error when is_write_cache is passed to dumps_to_bytes .
• Fix incorrect error message when unexpected keyword argument is passed.

Release 0.0.8

• #18 Use fastcall protocol to accelerate argument parsing. Small JSON will parse faster than before.
• #19 Support writing and reading UTF-8 cache. Largely improve performance. Add is_write_cache argument to dumps_to_bytes, and ssrjson.write_utf8_cache function. They are used for controlling the cache writing behavior. More details can be found in README.
• Internal refactors and fixes:
  • Use an accurate way to calculate the actual buffer size to reserve.
  • Statically assert 64-bits platform and having IEEE754 double.
  • Other small changes

Release 0.0.7

• Support MacOS (aarch64)
• Improve performance of dumps_to_bytes for ASCII path

No new feature was introduced compared to version 0.0.6

Release 0.0.6

From version 0.0.6, we will not distribute binary for Python3.9 since it has reached the end of life.

• Distribute binary for Python3.14
• Performance improvement for AVX2 encoding, and other improvements for encoding #14 #16
• Other internal refactors
