Version 2.0.0 released 2023-03-15 Additions: * Add a generic `register_preserialisation_callback` mechanism, which allows users to teach canonicaljson how to JSON-encode custom types. Breaking changes: * Remove support for serialising `frozendict` instances. Use the new `register_preserialisation_callback` mechanism to replace this functionality if needed. * Remove support for `simplejson` and the `set_json_library`alternative json libraries. Version 1.6.5 released 2023-02-15 * Update type hints to pass under mypy 1.0. Version 1.6.4 released 2022-11-04 * Remove unused `setuptools_scm` build requirement. Version 1.6.3 released 2022-09-23 * Properly package the `canonicaljson` module. Version 1.6.2 released 2022-06-08 * Bump version to 1.6.2 The v1.6.1 tag was created without having bumped the version in `canonicaljson.py`. This means that installing from source at the `v1.6.1` tag will install the package with the wrong version in its metadata. The 1.6.1 artefacts uploaded to PyPI did have the correct version; `pip install`ing directly from the archive resulted in a consistent version number. Version 1.6.1 released 2022-05-02 * Add type annotations. Version 1.6.0 released 2022-03-04 * `frozendict` is now an optional dependency; it is no longer required. Version 1.5.0 released 2021-10-20 * Switch CI from Travis to Github Actions * Add code to handle frozendict implementations using c-extension * Add tests for Python 3.10 * Remove outdated Debian packaging code Version 1.4.0 released 2020-09-03 * Fix producing non-standard JSON for Infinity, -Infinity, and NaN. This could cause errors when encoding objects into canonical JSON that previously used to work, but were incompatible with JSON implementations in other languages. * Use UTF-8 to fix ASCII encoding errors when data containing Unicode was attempted to be pretty-printed. Version 1.3.0 released 2020-08-14 * The minimum version of simplejson was bumped to 3.14.0. * Obsolete workaround for slow encoding of Unicode characters was removed. * New APIs were added to iteratively encode JSON. Version 1.2.0 released 2020-07-27 * JSON from the standard library is used automatically on PyPy. * Support for Python versions which are end-of-lifed was dropped, Python >= 3.5 is supported and tested in continuous integration. * An API to configure the underlying JSON library was added (`set_json_library`). Version 1.1.4 released 2018-05-23 * Fix error when encoding non-BMP characters on UCS-2 python builds (fixes issue #12). Version 1.1.3 released 2018-04-13 * Bump depencency on frozendict to >=1.0, to fix conflicts with older versions. Version 1.1.2 released 2018-04-12 * Fix escaping of control characters U+0000 to U+001F AGAIN, which was STILL broken in the previous release Version 1.1.1 released 2018-04-11 * Fix escaping of control characters U+0000 to U+001F, which was broken in the previous release Version 1.1.0 released 2018-04-06 * Significant performance improvements ([\#7](https://github.com/matrix-org/python-canonicaljson/pull/7), [\#8](https://github.com/matrix-org/python-canonicaljson/pull/8), [\#9](https://github.com/matrix-org/python-canonicaljson/pull/9)) Version 1.0.0 released 2015-08-21 * Initial release
