==== 24. October 2019 ====
=== 26. June 2025 ===
  - struggling with coin and therefore none of the scheduled releases went out
  - worked on multiple \brief attributes appearing in the docs
  - discussions started how to improve the general Qt for Python doc index page
  - investigating hiding C++ inline namespaces (e.g. Qt3D and QtCharts name spaces)
  - https://bugreports.qt.io/browse/PYSIDE-795 -> complete for 5.14 (merge pending)
    -> pysequence can be handled

** We need to catch up with the notes about some of the on-going processes: https://codereview.qt-project.org/c/pyside/pyside-setup/+/652346
    -> Qt Declarative needs change to enable QtfP binaries
** Future discussion on new Python Courses for Qt Academy
  - Qt for Python 5.15
* Infra & Releases
      -> currently not possible in CI
** CI: Fail to create env problem is still around (seems to be machine-related) - we could disable that config.
  - Qt for Python 5.13.2
** uv research still pending.
      -> in principle 5.13 branch is releasable (except there is an elaborate set of doc patches)
** 3.13 configs still pending.
  - split of QtfP project modules continues
* Bugs & Features
    -> dependencies defined via yaml
** Free threading
    -> adds the ability to also sign produced wheel.
*** The current researched approach with our own lock is not the best solution for PySide.
  - more example work
*** We have proof other people not picking this approach, and go with a sub-interpreter one: https://discuss.python.org/t/is-free-threading-our-only-option/91775
  - working on a semi translator to translate C++ snippets to Python
*** A different approach might be needed
  - visit to PyConDE
*** Our current testing infra is not enough to simply write tests for nogil python, and many hiccups have been found.
  - QSharePointer related fixes being worked on
*** Some tests cannot be replicated after some issues, so the nondeterministic behavior is a big challenge.
  - numpy proof-of-concept ([https://bugreports.qt.io/browse/PYSIDE-795 PYSIDE-795]) is available
** Qt AsyncIO notes
  - removed uic and rcc from pyside-setup since the Qt tools support Python now
*** A few ideas on how to finish the implementation was shared
  - exploring the idea to include designer in the Python wheels
*** The TCP protocol was initially implemented
  - discussion on supported Python versions (can we add 3.8 and remove 3.5?)
*** New tests were provided to continue the development in the future (using an asyncio event loop)
      -> more comms on the mailing list can be expected
** Some small tutorial to debug Python and C++, might need a follow-up
** Qt Creator discussion with people using old PySide versions, and using the new pyproject.toml approach.
** Cross building support on shiboken
*** yocto was not affected
*** we might need to check if iOS works
** PYSIDE-3095 small fix to pyside6-project
** Qt Python Scripting
*** Small internal API review
*** Cleanup
** To catch-up with the cmake improvements to our build system (orthogonal to the scikit-core research)
*** this will allow us to properly have the module as projects configures to be find them.
*** In the future, we will simplify our CMakeLists.txt for hybrid applications, a lot!
** iOS research continues
*** Cross compiling is still an issue due to the shared/static
*** OpenGL issue has a workaround, but still researching on the underneath
*** Waiting for shiboken to have compatibility with cross compiling to check if it works.

* Bugs & Features
  - Refined and closed [https://bugreports.qt.io/browse/PYSIDE-945 PYSIDE-945].
** Investigating improving support for std::optional [https://bugreports.qt.io/browse/PYSIDE-3107 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.

==== 15. August 2019 ====
=== 22. May 2025 ===
  - Partially solved [https://bugreports.qt.io/browse/PYSIDE-1052 PYSIDE-1052] (constants missing).
* General Topics
  - Solved at the same time [https://bugreports.qt.io/browse/PYSIDE-945 PYSIDE-945].
** Some updates from PyConUS
    Solved a QtCore.Slot() bug that dates back to 2010-11-03.
** Qt Bridges: We might participate at Akademy
  - Work on [https://bugreports.qt.io/browse/PYSIDE-1073 PYSIDE-1073] trying to fix the bug.
** Qt Bridges: We got an accepted talk https://ndctechtown.com/
  - Work on [https://bugreports.qt.io/browse/PYSIDE-1051 PYSIDE-1051] trying to fix the bug.
** Qt WS: Talk recording might be delayed to be public.
  - Merges/work on continuous integration infrastructure (preparing 5.13.1)
** 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.

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.
