==== 18. June 2020 ====
* General
** Bug fixing week
** PyConDE (Mon-Wed next week)
** Planning a workshop for TQtC solution engineers (internal)
** Possibility to include shiboken into the Axivion infra
* Infra & Releases
** 5.15.17 commercial LTS was postponed to Friday. Still need test on Windows.
** 6.5.6 release planned
** 6.7.1 release has been postponed to the first week of May
** DS-compatibility wheel postponed due to CI issues
** We might need to create a testing platform in order to check other errors that are not detectable with simple tests.
* Bugs & Features
** Few new type hints issues from 6.7.0 release, needs to be address on 6.7.1
** QtAsyncio issue related to Task groups. Tricky, because it can be related to Qt Events.
** PYSIDE-2629 Adding more Qt-tools to the wheels
** PYSIDE-2622 Adding a new option to the deploy tool (exposing an option from Nuitka)
** PYSIDE-2675 Lazy loading issues with trees of polymorphic classes.
*** first approach made things less effective
*** The impact of the solution was reduced a bit, by disabling the feature for special multiple-inheritance cases
*** New idea on 'groups' that be handled differently, so we have group or classes grouped and dependant
** 825 qml bug is still around
*** PYSIDE-2676 seems to be a new approach to fix it
** A few customer bugs made it the bug fixing week.
** PYSIDE-2675 type discovery code, class inheritance
** QtAudio -> QAudio refactory
** Virtual function compatibility to modify the signature (from typesystem)
** PYSIDE-2492 uic issues for Enum compatibility

* Infra update
===11. April 2024===
** The new windows wheels still had some issues, it seems the latest are OK, and we would need to publish '_2' wheels.
* General
** Some issues with macOS builds for 5.15.0
** Bug fixing week.
* Qt6 compatibility
** Qt 6.6.3 Library split broke our release, so we provided 6.6.3.1 as a fix.
** This is stopping the improvements in the QML integration story
** Qt 6.7.0 also had an issue with a binary incompatibility change on QtAudio and QAudio
** We need this merged before continuing https://codereview.qt-project.org/c/qt/qtbase/+/301979
** Maybe we implement a simple channel of communicating this details, in order to avoid breakage [maybe architect meetings]
* Merged a bug fix to 5.12 (the CI was not broken)
** Qt Creator 13 creates venvs automatically. This needs to be revisited to avoid multiple environments to be created.
* (in progress) Qt6 Properties camelCase to lower_case
** New epics with brainstorming ideas.
** Not a trivial task
* Infra & Releases
** It's possible to rename dynamically functions, and other things.
** 6.7.0 was released, we found a couple of issues we are trying to solve, and 6.7.1 will soon be released due to a binary compatibility break, and other small breakage.
** Containers needs to be taken care too
** 5.15.17 commercial LTS to be release next week.
** Having more than one object with the same ID is challenging
** QtDS packages a bit delay due to CI errors.

* (in progress) New StyleSheet tutorial.
** PYSIDE-2669 designer issue
==== 11. June 2020 ====
** PYSIDE-2675 Addressing the lazy import issues that were found in 6.7.0
*** Studying the possible solution, but it needs to consider other cases as well.
*** the *-import handling seems to be related, and affecting the mro content, duplicating some entries.
*** the type discovery handler might be related as well
** Still working on the qml 825 bug issues.

* OKRs Update
** Configuring additional embedded devices for RTA
** Looking for commercial opportunities
** Focus on spending some time on embedded linux, in order to see usability, and compatibility with Boot2Qt images.

** There are a couple of issues with one of the PYSIDE-803 patches that will be solved soon.
* Infra & Releases
** PYSIDE-164 is out of the picture
** Decouple of the commercial wheels in order to have a finer granularity and simpler tree on the Qt Installer (Maintenance Tool)
* Lambda functions for QWebEngineCallback PYSIDE-946 so we can expose the missing bindings.
** Qt for Python 6.6.2 is waiting for Qt to be released (by the end of the month)

** 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.
** 6.7 updates, adapting some warning messages
** QTBUG-99313 related issues

** 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
** Drop the bdist_wheel steps from the CI (old wheels)
** Started working on split commercial wheels, wheels for QtDS and examples on QtCreator.

      • first approach made things less effective
      • The impact of the solution was reduced a bit, by disabling the feature for special multiple-inheritance cases
      • New idea on 'groups' that be handled differently, so we have group or classes grouped and dependant
