Release Notes

• TTML reader now accepts optional parameter ignore_par_time_offset=True for compatibility with Apple Music TTML format (Issue #108)
• Refactoring to use pathlib.Path for paths, patch by Christopher Slycord (https://github.com/slycordinator)
• Type hints improvements, patch by Rafael Alexander Muijsert (https://github.com/RafaelMuijsert)
• CLI tests properly get path to Python binary, patch by Alexandre Detiste (https://github.com/a-detiste)
• Added support for Python 3.14
• Migrated from legacy Setuptools project to uv, hatch and pyproject.toml

1.8.0 --- released on 2024-12-24

• Added reader and writer for TTML subtitle format
• Added reader for SAMI subtitle format (Issue #80)
• Added reader for transcriptions from OpenAI Whisper JAX (Issue #73)
• Added py.typed file to allow MyPy to check types for code using this library, patch by eggplants (https://github.com/eggplants)
• Minor improvements to pysubs2.formats.substation.parse_tags() - now supports the \fn<fontname> tag, can optionally skip empty fragments
• Added support for Python 3.13, removed support for Python 3.8

1.7.3 --- released on 2024-07-27

• Fixed problem with multiprocessing.Pool crashing due to FormatAutodetectionError (Issue #97)

1.7.2 --- released on 2024-05-25

• Fixed problem with JSON format autodetection (Issue #94)

1.7.1 --- released on 2024-05-19

• Fixed missing pysubs2.formats subpackage in PyPI distributions (Issue #92)
• Test sdist and wheel distributions in CI

1.7.0 --- released on 2024-05-19 (yanked)

• Added errors option for :meth:pysubs2.load(), :meth:pysubs2.SSAFile.save() and related methods, exposing the encoding handling option of builtin function open(). By default, this option uses value None which is consistent with behaviour of previous versions of the library. However, it's possible to use "surrogateescape" to bypass the need to specify correct character encoding in some cases (see the tutorial). In the CLI, surrogateescape is now the default behaviour.
• SubStation writer now correctly handles timestamps which are not rounded to centiseconds, for example 00:36:48,998 from a SRT file no longer produces the invalid ASS timestamp 0:36:48.100 (Issue #83), patch by moi15moi (https://github.com/moi15moi)
• MicroDVD parser now only uses FPS declaration from the first subtitle if the line starts with {1}{1}, matching VLC Player behaviour; the old behaviour is available under the strict_fps_inference reader option (Issue #71)
