v2.8.4

PlotPy Version 2.8.4 (2026-02-14)

💥 New features:

• Added official support for Python 3.14

🛠️ Bug fixes:

• Fixed PySide6 compatibility issues causing segfaults in the test suite:
  • Use object instead of C++ type strings (e.g., "QMouseEvent", "QEvent", "QPointF") in Signal declarations — PySide6 segfaults with C++ type name strings
  • Check QObject validity via is_qobject_valid() before accessing widgets in __del__, closeEvent, and panel close operations — PySide6 segfaults on deleted C++ objects instead of raising RuntimeError
  • Restructure BaseSyncPlot.__init__ to defer widget operations until after Qt __init__ completes — PySide6 requires __init__ to have fully completed before the widget can be used as a parent
  • Replace deprecated exec_() calls with exec()
• Fixed test_multiline_tool failing with PyQt6 due to smaller canvas size:
  • The spiral test data started at t=0, placing the first two points so close together that they mapped to the same pixel on PyQt6's smaller default canvas
  • Start the spiral at t=2π to ensure sufficient pixel spacing between consecutive points
• Fixed pytest running all tests when selecting a single test from VS Code:
  • Move plotpy from addopts to testpaths in [tool.pytest.ini_options]

🔧 Other changes:

• Add missing setuptools to requirements.txt (dev)
• Update GitHub Actions to use latest artifact upload and download versions
• Update cibuildwheel version to v3.3.1 for improved wheel building
• Add .venv* to .gitignore to exclude virtual environment files
