Version 4.1.1 released 2026-04-24

* The ``build_wheels_py27`` CI job now also builds Python 2.7 wheels
  for Windows AMD64 and Windows x86, joining the existing Py2.7
  manylinux1 / manylinux2010 x86_64 wheels. This unblocks offline /
  ``--no-index`` installs on Py2.7-on-Windows (the original
  reporter's case), which previously had no matching binary wheel on
  PyPI, fell through to the sdist, and failed on the PEP 517
  isolated-build step complaining that ``setuptools>=42`` was not in
  the wheelhouse.
  https://github.com/simplejson/simplejson/issues/377

Version 4.1.0 released 2026-04-22

* The C extension now accelerates encoding when ``indent=`` is set.
  Previously the encoder fell back to the pure-Python implementation
  whenever a non-None ``indent`` was passed; now the C encoder emits
  the newline-plus-indent prefix, the level-aware item separator, and
  the closing indent directly.  A representative nested-dict workload
  benchmarks about 4-5x faster end-to-end, and the ``indent=0`` and
  empty-container edge cases continue to match the Python output
  byte-for-byte.

* The C extension now emits PEP 678 ``exc.add_note()`` annotations on
  serialization failures, matching the pure-Python encoder.  A chained
  error on ``{'a': [1, object(), 3]}`` produces the same three notes
  (``when serializing object object``, ``when serializing list item 1``,
  ``when serializing dict item 'a'``) whether the speedups are loaded
  or not, so the add_note assertions in ``test_errors.py`` no longer
  need ``indent=2`` to force the Python path.

Version 4.0.1 released 2026-04-18

* Skip uploading Pyodide/wasm wheels to PyPI, which rejects them with
  "unsupported platform tag 'pyodide_2024_0_wasm32'". The wheels are
  still built in CI and preserved as workflow artifacts.
  https://github.com/simplejson/simplejson/pull/375

Version 4.0.0 released 2026-04-18

* simplejson 4 requires Python 2.7 or Python 3.8+. Older Python
  versions (2.5, 2.6, 3.0-3.7) are no longer supported. pip will
  not install simplejson 4 on unsupported versions.

* The C extension now uses heap types and per-module state instead of
  static types and global state. This is required for free-threading
  support and sub-interpreter isolation. The Python-level API is
  unchanged.

* Full support for Python 3.13+ free-threading (PEP 703). The C
  extension is now safe to use with the GIL disabled (python3.14t):
  - Converted all static types to heap types with per-module state
  - Added per-object critical sections to scanner and encoder
  - Added free-threading-safe dict operations for Python 3.13+
  - Unified per-module state management and templated parser
  https://github.com/simplejson/simplejson/pull/363
  https://github.com/simplejson/simplejson/pull/364
  https://github.com/simplejson/simplejson/pull/365
  https://github.com/simplejson/simplejson/pull/367
  https://github.com/simplejson/simplejson/pull/369

* Numerous C extension memory safety fixes:
  - Fix use-after-free and leak in encoder ident handling
  - Fix NULL dereferences on OOM in module init and static string init
  - Fix reference leaks in dict encoder (skipkeys item, variable shadowing)
  - Fix member table copy-paste, exception clobbering, missing Py_VISIT
  - Fix error-as-truthy bugs in maybe_quote_bigint and is_raw_json
  - Fix iterable_as_array swallowing MemoryError and KeyboardInterrupt
  - Fix for_json and _asdict swallowing MemoryError, KeyboardInterrupt,
    and other non-AttributeError exceptions raised by user __getattr__

  https://github.com/simplejson/simplejson/pull/359
  https://github.com/simplejson/simplejson/pull/360
  https://github.com/simplejson/simplejson/pull/373

* C/Python parity fixes:
  - Fix C scanstring off-by-one bounds checks that caused truncated
    or boundary \uXXXX escapes to raise "Invalid \\uXXXX escape
    sequence" instead of "Unterminated string", and report error
    position at the 'u' instead of the leading backslash. The C and
    Python decoders now agree on exception class, message, and
    position across all tested edge cases.
  - Align the Python encoder's dispatch order with the C encoder for
    objects that define _asdict(). Previously a list/tuple/dict
    subclass with an _asdict() method encoded as its container type
    under the Python encoder and as the _asdict() return value under
    the C encoder; both now check _asdict() before list/tuple/dict.
    for_json() continues to outrank _asdict() in both.
  - Fix C scanstring raising a plain ValueError ("end is out of
    bounds") instead of JSONDecodeError for out-of-range end indices.
    User code with `except JSONDecodeError:` now catches both the
    C and pure-Python paths consistently.
  https://github.com/simplejson/simplejson/pull/372

* C extension performance and correctness improvements:
  - Add PyDict_Next fast path for unsorted exact-dict encoding,
    avoiding intermediate items list and N tuple allocations
  - Add indexed fast path for exact list/tuple encoding, avoiding
    iterator allocation and per-item PyIter_Next overhead
  - Use PyUnicodeWriter as JSON_Accu backend on Python 3.14+,
    eliminating intermediate string objects and ''.join calls
  - Fix integer overflow in ascii_escape output_size calculation
    that could cause buffer overwrite on pathologically large strings
  - Fix list encoder separator counter overflow (int to Py_ssize_t)
  - Dead code cleanup (unreachable NULL checks, do-while wrappers)
  https://github.com/simplejson/simplejson/pull/370

* Added Python 3.14 support and updated to cibuildwheel 3.2.1. CI now
  tests free-threaded (3.14t) and debug builds with -Werror, refcount
  leak detection, and GIL-disabled mode.
  https://github.com/simplejson/simplejson/pull/343

* Added a ThreadSanitizer (TSan) stress test CI job. Builds a
  TSan-instrumented free-threaded CPython (cached between runs) and
  runs a concurrent stress test script against the C extension to
  catch data races under free-threading.
  https://github.com/simplejson/simplejson/pull/373

* Replace deprecated license classifiers with SPDX license expression
  https://github.com/simplejson/simplejson/pull/347

* Documented RawJSON usage with examples and caveats
  https://github.com/simplejson/simplejson/pull/346

* Added pyproject.toml for PEP 517 build support. setup.py is retained
  for Python 2.7 wheel builds and backwards compatibility.

* Migrated build_ext import from distutils to setuptools in setup.py.
  The distutils.errors imports are kept since setuptools vendors
  distutils on Python 3.12+ where stdlib distutils was removed.

* CI now tests PEP 517 builds (pyproject.toml) alongside the existing
  setup.py-based builds.

* Added Pyodide (wasm32) wheel builds with C speedups via cibuildwheel.
  Previously Pyodide users fell back to the pure-Python wheel; now they
  get the compiled C extension cross-compiled to WebAssembly. Thread
  and subprocess tests are skipped on Emscripten where those APIs are
  unavailable.

* Test suite now fails (instead of skipping) when C speedups are missing
  during cibuildwheel runs, catching broken extension builds early.

* New ``array_hook`` parameter for ``loads()``, ``load()``, and
  ``JSONDecoder``. Called with each decoded JSON array (as a list),
  its return value replaces the list. Analogous to ``object_hook``
  for dicts. Works with both the Python decoder and C scanner.
  (Matches CPython 3.15 json module.)

* Trailing comma detection: the decoder now raises ``JSONDecodeError``
  with "Illegal trailing comma before end of object/array" for inputs
  like ``[1,]`` and ``{"a": 1,}`` instead of generic error messages.
  Both the Python decoder and C scanner are updated.
  (Matches CPython 3.13+ json module.)

* ``frozendict`` encoding support: when ``frozendict`` is available
  (CPython 3.15+ PEP 814), it is encoded as a JSON object just like
  ``dict``. No effect on older Python versions.

* Serialization errors now include ``add_note()`` context on Python
  3.11+ (PEP 678), annotating exceptions with the path to the error,
  e.g. "when serializing list item 1" / "when serializing dict item
  'key'". Only applies to the Python encoder.

* New C fast path for ``encode_basestring`` (``ensure_ascii=False``).
  Previously the non-ASCII string encoder fell back to pure Python;
  now it has a C implementation matching the existing
  ``encode_basestring_ascii`` fast path.
  https://github.com/simplejson/simplejson/issues/207

* The Python decoder now rejects non-ASCII digits (e.g. fullwidth
  ``\uff10``) in JSON numbers, matching the C scanner behavior.
  The ``NUMBER_RE`` regex was changed from ``\d`` to ``[0-9]``.

* Removed dead single-phase init code for Python 3.3/3.4 from the
  C extension (these versions are no longer supported).

* Updated test & build matrix to include Python 3.12 and use
  GitHub Actions as a Trusted Publisher (OIDC)
  https://github.com/simplejson/simplejson/pull/317

Version 3.19.1 released 2023-04-06

* This release contains security hardening measures based on recommendations
  by a security audit sponsored by OSTIF and conducted by X41 D-Sec GmbH.
  Several of these measures include changing defaults to be more strict,
  by default simplejson will now only consume and produce compliant JSON,
  but the flags still exist for any backwards compatibility needs.
  No high priority issues were discovered, the reference count
  leak is thought to be unreachable since the digits of the float are
  checked before PyOS_string_to_double is called.
  A link to the public version of this report will be included in a
  future release of simplejson. The following fixes were implemented in
  one PR: https://github.com/simplejson/simplejson/pull/313
* Fix invalid handling of unicode escape sequences in the pure Python
  implementation of the decoder (SJ-PT-23-01)
* Fix missing reference count decrease if PyOS_string_to_double raises
  an exception in Python 2.x; was probably unreachable (SJ-PT-23-02)
* Backport the integer string length limitation from Python 3.11 to
  limit quadratic number parsing (SJ-PT-23-03)
* Fix inconsistencies with error messages between the C and Python
  implementations (SJ-PT-23-100)

  not essential to upgrade
* Tests now run with deprecation warnings printed
* Fixed Python 3 syntax error in simplejson.tool
  https://github.com/simplejson/simplejson/issues/49
* Fixed Python 3.3 deprecation warnings in test suite
  https://github.com/simplejson/simplejson/issues/48

* Fixes for Python 2.5 compatibility
* MSVC compatibility for Python 2.x
  https://github.com/simplejson/simplejson/pull/46

Version 3.0.2 released 2013-01-01

* THIS VERSION HAS BEEN REMOVED
* Missed a changeset to _speedups.c in the 3.0.1 branch cut

Version 3.0.1 released 2013-01-01

* THIS VERSION HAS BEEN REMOVED
* Add accumulator optimization to encoder, equivalent to the usage of
  `_Py_Accu` in the Python 3.3 json library. Only relevant if encoding
  very large JSON documents.

Version 3.0.0 released 2012-12-30

* Python 3.3 is now supported, thanks to Vinay Sajip
  https://github.com/simplejson/simplejson/issues/8
* `sort_keys`/`item_sort_key` now sort on the stringified version of the
  key, rather than the original object. This ensures that the sort
  only compares string types and makes the behavior consistent between
  Python 2.x and Python 3.x.
* Like other number types, Decimal instances used as keys are now
  coerced to strings when use_decimal is True.

  and treated as a tuple with the new namedtuple_as_object=False option.
  https://github.com/simplejson/simplejson/pull/6
* JSONDecodeError is now raised instead of ValueError when a document
  ends with an opening quote and the C speedups are in use.
  https://github.com/simplejson/simplejson/issues/15

* Fixed containerless unicode float decoding (same bug as 2.0.4, oops!)
  http://code.google.com/p/simplejson/issues/detail?id=43
* Share PosInf definition between encoder and decoder
* Minor reformatting to make it easier to backport simplejson changes
  to Python 2.7/3.1 json module

Version 2.0.9 released 2009-02-18

* Adds cyclic GC to the Encoder and Scanner speedups, which could've
  caused uncollectible cycles in some cases when using custom parser
  or encoder functions

Version 2.0.8 released 2009-02-15

* Documentation fixes
* Fixes encoding True and False as keys
* Fixes checking for True and False by identity for several parameters

Version 2.0.7 released 2009-01-04

* Documentation fixes
* C extension now always returns unicode strings when the input string is
  unicode, even for empty strings

Version 2.0.6 released 2008-12-19

* Windows build fixes

Version 2.0.5 released 2008-11-23

* Fixes a segfault in the C extension when using check_circular=False and
  encoding an invalid document

Version 2.0.4 released 2008-10-24

* Fixes a parsing error in the C extension when the JSON document is (only)
  a floating point number. It would consume one too few characters in that
  case, and claim the document invalid.

Version 2.0.3 released 2008-10-11

* Fixes reference leaks in the encoding speedups (sorry about that!)
* Fixes doctest suite for Python 2.6
* More optimizations for the decoder

Version 2.0.2 released 2008-10-06

* Fixes MSVC2003 build regression
* Fixes Python 2.4 compatibility in _speedups.c

Version 2.0.1 released 2008-09-29

* Fixes long encoding regression introduced in 2.0.0
* Fixes MinGW build regression introduced in 2.0.0

Version 2.0.0 released 2008-09-27

* optimized Python encoding path
* optimized Python decoding path
* optimized C encoding path
* optimized C decoding path
* switched to sphinx docs (nearly the same as the json module in python 2.6)

Version 1.9.3 released 2008-09-23

* Decoding is significantly faster (for our internal benchmarks)
* Pretty-printing tool changed from simplejson to simplejson.tool for better
  Python 2.6 comaptibility
* Misc. bug fixes

Version 1.9 released 2008-05-03

* Rewrote test suite with unittest and doctest (no more nosetest dependency)
* Better PEP 7 and PEP 8 source compliance
* Removed simplejson.jsonfilter demo module
* simplejson.jsonfilter is no longer included

Version 1.8.1 released 2008-03-24

* Optional C extension for accelerating the decoding of JSON strings
* Command line interface for pretty-printing JSON (via python -msimplejson)
* Decoding of integers and floats is now extensible (e.g. to use Decimal) via
  parse_int, parse_float options.
* Subversion and issue tracker moved to google code:
  http://code.google.com/p/simplejson/
* "/" is no longer escaped, so if you're embedding JSON directly in HTML
  you'll want to use .replace("/", "\\/") to prevent a close-tag attack.

Version 1.7 released 2007-03-18

* Improves encoding performance with an optional C extension to speed up
  str/unicode encoding (by 10-150x or so), which yields an overall speed
  boost of 2x+ (JSON is string-heavy).
* Support for encoding unicode code points outside the BMP to UTF-16
  surrogate code pairs (specified by the Strings section of RFC 4627).

Version 1.6 released 2007-03-03

* Improved str support for encoding. Previous versions of simplejson
  integrated strings directly into the output stream, this version ensures
  they're of a particular encoding (default is UTF-8) so that the output
  stream is valid.

Version 1.5 released 2007-01-18

* Better Python 2.5 compatibility
* Better Windows compatibility
* indent encoding parameter for pretty printing
* separators encoding parameter for generating optimally compact JSON

Version 1.3 released 2006-04-01

* The optional object_hook function is called upon decoding of any JSON
  object literal, and its return value is used instead of the dict that
  would normally be used. This can be used to efficiently implement
  features such as JSON-RPC class hinting, or other custom decodings of
  JSON. See the documentation for more information.

Version 1.1 released 2005-12-31

* Renamed from simple_json to simplejson to comply with PEP 8 module naming
  guidelines
* Full set of documentation
* More tests
* The encoder and decoder have been extended to understand NaN, Infinity, and
  -Infinity (but this can be turned off via allow_nan=False for strict JSON
  compliance)
* The decoder's scanner has been fixed so that it no longer accepts invalid
  JSON documents
* The decoder now reports line and column information as well as character
  numbers for easier debugging
* The encoder now has a circular reference checker, which can be optionally
  disabled with check_circular=False
* dump, dumps, load, loads now accept an optional cls kwarg to use an
  alternate JSONEncoder or JSONDecoder class for convenience.
* The read/write compatibility shim for json-py now have deprecation warnings

Version 1.0 released 2005-12-25

 * Initial release
