** Conferences: submissions to PyCon SK, PyCon DE, PyCon LT, PyCon US
  - in the long term, the qdoc generation process should really produce python docs too
* Infra & Releases
  - updated coin to continue to include QtXmlPattern for Qt for Python builds
** Decouple of the commercial wheels in order to have a finer granularity and simpler tree on the Qt Installer (Maintenance Tool)
- [https://bugreports.qt.io/browse/PYSIDE-996 PYSIDE-996] fixed on SuSE but not yet RedHat

- improving primitive type conversion (by the various OpenGL related bugs like PYSIDE-989 or PYSIDE-955)
** SingleShot timer issue: Slight "complexity explosion" because correct implementation for one case requires implementation of QObject.connect overload with context arguments (and we implement QObject.connect ourselves, see PySide::qobjectConnectCallback).

** Documentation updates to fix issues we had.
** Unity build some issues when building without.

*** https://peps.python.org/pep-0690/ was rejected, but the idea can be implemented per-module
** Moving entry_points declaration to pyproject.toml from setup.py

    • Maybe we implement a simple channel of communicating this details, in order to avoid breakage [maybe architect meetings]
