      • Move virtual function overrides. Only generated on the base classes.
      • Discovered and fixed a few multiple inheritance with shiboken
    • Snippets translation tool: Trying to add a feature to use fully qualified enums.
    • clang-tidy warnings were fixes
    • Handling value types on non-default constructors (inspired by 6.9 changes)
    • Discussion on moving away out internal building process to scikit-build
    • Size reduction (folding approach): To publish first results soon.
    • Supporting team member with pyi session to understand the internal mechanism.
    • Ideas from the size reduction research were implemented
    • Changing the benchmark code for the size reduction (which might not include the new changes to shiboken)

  • Infra & Releases
    • Preparing 6.8.2
  • Bugs & Features
    • Size reduction PYSIDE-2701 : Implemented code reuse for Python overrides of virtual functions
    • QtPythonScripting: continue working on multiple inheritance, added more widgets
    • Size reduction: PYSIDE-2701 Folding progress: We can now combine multiple foldings of the same function. This will bring some more reduction.
    • Simplebrowser example updated
    • adding imageviewer docs

  • General
  • Infra & Releases
    • Windows on ARM configuration testing.
    • 6.8.2 scheduled release next week, and branching will happen today.
  • Bugs & Features
    • QtPythonScripting: continue working on Stable ABI support and multiple inheritance
    • [ext] 6.9 Designer release issues with macOS drag and drop + bug fixing
    • PYSIDE-2990 Slot Executed in Signal's Thread Even With Auto & QueuedConnection
      • People is getting the documentation from an outdated wiki page, which is causing new reports.
      • Wiki will be updated.
    • Size reduction: we generate a lot of code for parsing keyword arguments. The code was moved to libshiboken and the size was reduced 3%
      • Optimization reviews: it seems it's only the virtual functions, but not the actual bindings.
    • Size reduction: Windows is giving some issues for special characters, which seems to be also present in Linux.
    • Cross compiling and creating wheels with the new JNI classes bindings. Trying to test them in an emulator, found other issues.
    • pyside6-deploy/project and DS changes integrating, hopefully they will be merged today \o/
    • DS-only changes are still in review.
    • TOML integration - continue research on adding new format for python projects
    • QtGraphWidgets issue with yocto build was fixed.

  • General
    • Highly probable that one of us will go to FOSDEM to help with the Qt Project stand! so if you /reader/ are going, drop by and say hi!
  • Infra & Releases
    • 6.8.2 will be released on 23th January so far, so we expect providing the wheels in the following days.
    • 3.13 on the CI still on-going.
    • 6.5.4 OSS released
  • Bugs & Features
    • Discussion about QJni* bindings when cross compiling.
      • It did built (and installed) for aarch64 and x86_64 but armv7a will be tried later on.
      • The main issue with this story was that it was bindings only for cross compiled pyside
    • Exploring toml compatibilities within QtCreator
    • DS patches still needs review.
    • Binary size work continues
      • 17% reduction so far, and this could be included in the future-features list.
      • Once is ready, we might provide an option to disable it to go back to the more readable wrapper code.
      • We might evaluate a template approach once the solution is out, to avoid maintaining regexes.
    • Remote Object reviews ready in order to merge changes (only a few details)
    • Qt Python Scripting
      • Multiple inheritance is not supported yet.
      • REPL function to help development
      • Research on Limited API usage.
      • find_python macro in 3.26 allow to find the stable abi
    • docstring changes in order to expose them as docstring per methods.
      • some experiment to add it to the pyi files, but it doesn't show.
