=== 22. May 2025 ===
* General Topics
** Some updates from PyConUS
** Qt Bridges: We might participate at Akademy
** Qt Bridges: We got an accepted talk https://ndctechtown.com/
** Qt WS: Talk recording might be delayed to be public.
** PyCon IT: Going there to give a talk
** Windows on ARM is getting more attention from other companies.
*** There is currently an issue with OpenGL (not being in Qt, hence not in Qt for Python)
*** FreeCAD requires opengl for some reason :S
* Infra & Releases
* Infra & Releases
** 6.5.1 Preparations
** 5.15.19 commercial LTS was released
** 5.15.14 Preparations
** 6.9.1 postponed by a regression
** 6.5.9 still pending (security fix)
** We might evaluate uv for CI
* Bugs & Features
* Bugs & Features
** Fixed [https://bugreports.qt.io/browse/PYSIDE-2325 PYSIDE-2325] typesystem incomplete
** We will work on being more compatible with uv (shiboken issue finding dlls)
** Fixed [https://bugreports.qt.io/browse/PYSIDE-2328 PYSIDE-2328] Segmentation fault/access violation when connecting signal of temporary object
** iOS research: managed to cross compile the project, but there seems to be an issue still when trying to use it from XCode side of things. We might need to try the setup.py approach rather than CMake.
** Fixed [https://bugreports.qt.io/browse/PYSIDE-2329 PYSIDE-2329] Signal connections with init kwargs
** API deprecations that needs to be handle: missing functions on the typesystem and in some test cases. QtXml (QDomDocument) missing new function needs to be added as well (overload issue). Some works needs to be done in the examples as well.
** Reverted temporarily the delayed exception patch, in order to not block the 6.5.1 release. This should be discussed at the next meeting
** Thoughts on limiting the disable gil solution that we have at the moment. There has been a lot of crashes and issues by implementing our own locking mechanism.
*** Fixed [https://bugreports.qt.io/browse/PYSIDE-2310 PYSIDE-2310]
** QtAsyncIO has been brought up in some community discussions, so we might work more on this. There are many NotImplemented issues around, that would be good to have.
*** Fixed [https://bugreports.qt.io/browse/PYSIDE-2321 PYSIDE-2321]
** Qt Python Scripting: Aiming for 6.11, and to find a place to distribute it. Due to the limitation of virtual functions, it's mostly about doing a bit of scripting on top of the Qt/C++ applications. Does it justify it to be a new Qt module? maybe we could use Qt solutions. We need another person to check the API, to have a second opinion.
*** There are some ideas of virtual-function override from pybind11, but then we would require shiboken ownership mechanisms, that will increase dependencies (and size)
*** Release process of qt-modules is strict.
** PYSIDE-2193 variance in QML Properties. QVariant/PyObjects issues were found and fixed.
** Got interest of doing RTA internally, that's generating more reports.
** CMake relocation files shipping that are not being included anymore (headers or cmake files), but got required by Qt Bridges.
** New cmake variables are being required for Qt Bridges.
** Message handler changes are still pending for CI issues.

* General
** We are probably presenting at QtWS!
** Check our PyPI organization page: https://pypi.org/org/Qt/
** https://peps.python.org/pep-0751/ https://peps.python.org/pep-0768/

* Bugs & Features
** Adding property support for QML bridges
** Minor changes to the deployment tool, and qtpip
** Working on the presentation for QtWS
** Continue the research for iOS support, it seems there are a few issues with the other frameworks that support it.
*** Distributing apps on iOS is tricky, it requires a Dev account ($$), with a free account you can only upload the app with a cable for 7 days, and then it expires (We wonder what would happen with data)
*** For uploading, you need to turn-on developer mode, which raises a message of "privacy being reduced"
*** iPad applications seems to have the same behavior.
** Might check https://github.com/benfogle/crossenv and https://github.com/beeware/mobile-forge
** PYSIDE-3059 was fixed
** PYSIDE-3012 was updated with new suggestions
** Free threading Python support continues PYSIDE-2221
*** A few changes we had for nogil are not necessary anymore.
*** Our mandelbrot example didn't show a good performance. After discussion with CPython core devs, there was an issue on Python 3.13.{1,2} (not on 3.13.0) that made some slowness. (On M1 it was 8x faster, but now it was 4.3x, the speed lost causes are still in research)

5. June 2025

  • General Topics
  • Infra & Releases
  • Bugs & Features
    • PYSIDE-3187 std::optional handling from new qt api (having an intrinsic type rather than a separate one)
    • Trying QRangeModel for some Python examples. (new api in 6.10)
    • Adapting to 6.10
    • Virtual Keyboard issue: missing files for plugins issue was fixed
    • PYSIDE-3112 android deployment issue
    • Finishing the CMake config files for shiboken/pyside in order to get more options once it's installed. This might help us simplifying use cases like scriptableapplication.
    • Updated flatpak package, and a new issue related to missing tools.
    • iOS research
      • Managed to embed Python in an iOS application
      • there seems to be an issue with linking between so files
      • dynamics libs are needed, but removing a few .so files PySide is not recognized. When removing the frameworks ones, another issue appear, when having them both, there is also an issue.
      • We might need to re-think the OpenGL finds for iOS patches
    • QtCreator wizard uses pyproject.toml

29. May 2025

  • General Topics
  • Infra & Releases
    • Preparing 6.9.1, 6.5.9
    • Further work adapting to 6.10, QRangeModel renamed from QGenericItemModel
  • Bugs & Features
    • Investigating improving support for std::optional PYSIDE-3107
    • Progressing with shipping CMake configs with PySide6 and Shiboken6 wheels. Trickly resolving install time and packaging configuration. Had to resort to patch the CMake configs before packaging.
    • QPropertyAnimation constructor annotations fixed PYSIDE-3012
    • Continued work on XCode and library binding, minor problems with Python libraries and trying to integrate PySide6 libraries.
    • PYSIDE-2221: Status report is in progress for potential handover.
    • PYSIDE-769:
      • Integration and activation of QtAsync tests into the test framework.
      • First implementation of a TCP transport; server tests are working.

22. May 2025

  • General Topics
    • Some updates from PyConUS
    • Qt Bridges: We might participate at Akademy
    • Qt Bridges: We got an accepted talk https://ndctechtown.com/
    • Qt WS: Talk recording might be delayed to be public.
    • PyCon IT: Going there to give a talk
    • Windows on ARM is getting more attention from other companies.
      • There is currently an issue with OpenGL (not being in Qt, hence not in Qt for Python)
      • FreeCAD requires opengl for some reason :S
  • Infra & Releases
    • 5.15.19 commercial LTS was released
    • 6.9.1 postponed by a regression
    • 6.5.9 still pending (security fix)
    • We might evaluate uv for CI
  • Bugs & Features
    • We will work on being more compatible with uv (shiboken issue finding dlls)
    • iOS research: managed to cross compile the project, but there seems to be an issue still when trying to use it from XCode side of things. We might need to try the setup.py approach rather than CMake.
    • API deprecations that needs to be handle: missing functions on the typesystem and in some test cases. QtXml (QDomDocument) missing new function needs to be added as well (overload issue). Some works needs to be done in the examples as well.
    • Thoughts on limiting the disable gil solution that we have at the moment. There has been a lot of crashes and issues by implementing our own locking mechanism.
    • QtAsyncIO has been brought up in some community discussions, so we might work more on this. There are many NotImplemented issues around, that would be good to have.
    • Qt Python Scripting: Aiming for 6.11, and to find a place to distribute it. Due to the limitation of virtual functions, it's mostly about doing a bit of scripting on top of the Qt/C++ applications. Does it justify it to be a new Qt module? maybe we could use Qt solutions. We need another person to check the API, to have a second opinion.
      • There are some ideas of virtual-function override from pybind11, but then we would require shiboken ownership mechanisms, that will increase dependencies (and size)
      • Release process of qt-modules is strict.
    • PYSIDE-2193 variance in QML Properties. QVariant/PyObjects issues were found and fixed.
    • Got interest of doing RTA internally, that's generating more reports.
    • CMake relocation files shipping that are not being included anymore (headers or cmake files), but got required by Qt Bridges.
    • New cmake variables are being required for Qt Bridges.
    • Message handler changes are still pending for CI issues.
