* General
** Bug fixing week.
** Qt 6.6.3 Library split broke our release, so we provided 6.6.3.1 as a fix.
** Qt 6.7.0 also had an issue with a binary incompatibility change on QtAudio and QAudio
** Maybe we implement a simple channel of communicating this details, in order to avoid breakage [maybe architect meetings]
** Qt Creator 13 creates venvs automatically. This needs to be revisited to avoid multiple environments to be created.
** New epics with brainstorming ideas.
* Infra & Releases
** 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.
**  5.15.17 commercial LTS to be release next week.
** QtDS packages a bit delay due to CI errors.
** Qt Installer (Maintenance tool) has  still some issues with the structure.
* Bugs & Features
** Adding new Qt tools to the wheels (wrappers)
** PYSIDE-2602 special virtual function research
** PYSIDE-2669 designer issue
** 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.
