* Infra & Releases
** no unity build discussion and checks
** 6.6.2 to be released next week.
** More granularity on the commercial wheels: shiboken wizard wheel.
* Bugs & Features
** singleShot timer implementation (to use underlying c++ impl) - still an issue with a context object, and a signal as a functor. A new QObject::connect might handle the situation. More changes to come in order to fix newly discovered issues.
** Android: using the master branch on python-for-android, and other changes related for macOS deployment.
** PYSIDE-2597 optimization for the deployment procedure
** Lazy initialization: works continues, and it's looking good. 13 bugs to go on lazy mode. The new implementation seems to be working better.
** 6.7 adaptation still in progress (many changes from Qt)
** General documentation adjustments
** Improvements on shiboken: better error messages
** Qt Namespaces compatibility attempts.
** Moving away from a couple of setup.py options towards pyproject.toml after upgrading 'build' to 1.0.x

===25. January 2024===
 
* General
** Configuring additional embedded devices for RTA
** Focus on spending some time on embedded linux, in order to see usability, and compatibility with Boot2Qt images.
** Conferences: submissions to PyCon SK, PyCon DE, PyCon LT, PyCon US

** New CI configuration without '--unity' for manual testing, to spot issues.
* Bugs & Features
** VS Code will use .flake8 (formerly setup.cfg) file for configuration once merged
** PYSIDE-2575: Added a new argument to QtAsyncio to configure whether the QCoreApplication at the core of QtAsyncio should be shut down when asyncio finishes (requested by user).
** 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).
** Scripting: code simplification, and massage it to a Qt module.
** Documentation updates to fix issues we had.
** Unity build some issues when building without.

** Android wheels provisioning and configuration in order to generate the base-wheels.
** armv7 complications due to an upstream find_python command.
** Lazy initialization: re-wrote approach from scratch, to reduce the patches to one that can be analyzed easily. Some complications with this approach that needs to be improve. It can be tried with https://codereview.qt-project.org/c/pyside/pyside-setup/+/496118
*** 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
