* General
* General Topics
** QtWS - One talk accepted
** Some updates from PyConUS
** Europython - One talk accepted
** 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 one issue was found, so release will be available once we merge the fix.
** 5.15.19 commercial LTS was released
** 5.15.14 to be release soon.
** 6.9.1 postponed by a regression
** CI arm64 experiments continue
** 6.5.9 still pending (security fix)
** Asking about M2M wheels on the maintenance tool, for 6.6
** We might evaluate uv for CI
** Solving LTS issues of missing tags on public repo, might take some time.
* Bugs & Features
* Bugs & Features
** Evaluating shiboken6_generator to be published on PyPi
** We will work on being more compatible with uv (shiboken issue finding dlls)
** Few small fixes around the project (release preparation, new features, small bugs, doc issues)
** 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.
** QtScrypt experimental work continues
** 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.
** Permission API added (motivated by the android support)
** 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.
** Improvements for the android deployment.
** 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.
** Trying to fix an issue of getting Enums to Ints
** 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.
** Delayed exceptions work continues, trying to fix some corner cases still.
*** There are some ideas of virtual-function override from pybind11, but then we would require shiboken ownership mechanisms, that will increase dependencies (and size)
** Starting to explore PEP 658
*** Release process of qt-modules is strict.
** Research on PyTest compatibility
** PYSIDE-2193 variance in QML Properties. QVariant/PyObjects issues were found and fixed.
** [Designer] Fixing some issues, and warnings
** 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/
** There will be a local meetup in Berlin, where Shiboken will be mentioned and explained a bit https://www.meetup.com/pyberlin/events/306654979/
* Infra & Releases
** 6.8.3 and 6.9.0 were released.
** Android wheels for 6.9.0 were generated differently for a CI NDK misconfiguration.
** Flatpak releases are waiting for the webengine flatpack update first.
* 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)

2025

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.
