** Deployment functionality being studied for pyside6-projet
** QML Wayland issue discovered while porting an example
** Following up on a former QUrl issue that was an overlook, not a bug.

** Working towards Debian PySide packages, adapting many things.
** PyEnum revealed bugs when partially moving from IntEnum to Enum, making issue splitting necessary:
*** QKeySequence implementation was fixed
*** a few more problems to be solved before final check-in of the PyEnum conclusion
*** Then PyEnum documentation will become complete and will be finished, next.

*General
=== 3. April 2025 ===
*Infra & Releases
* General
**6.2.5 commercial LTS wheels to be published.
** We are probably presenting at QtWS!
**PyPy CI issue remains, but some ideas in place
** Check our PyPI organization page: https://pypi.org/org/Qt/
**Enabling Python betas: maybe we could use a new COIN feature.
** https://peps.python.org/pep-0751/ https://peps.python.org/pep-0768/
*Bugs & Features
** There will be a local meetup in Berlin, where Shiboken will be mentioned and explained a bit https://www.meetup.com/pyberlin/events/306654979/
**PyEnum chain is ready for review
* Infra & Releases
**https://bugreports.qt.io/browse/PYSIDE-1988 Old shiboken was found and fixed
** 6.8.3 and 6.9.0 were released.
***We need to check the interfaces more often, otherwise we will find nasty issues like this one.
** Android wheels for 6.9.0 were generated differently for a CI NDK misconfiguration.
**https://bugreports.qt.io/browse/PYSIDE-1960 was finally fixed as well and compatible with the new PyEnum approach.
** Flatpak releases are waiting for the webengine flatpack update first.
**https://bugreports.qt.io/browse/PYSIDE-1735 seems to be trickier
* Bugs & Features
***complicated only to keep compatibility with the old Enum approach.
** Adding property support for QML bridges
**Documentation for the new Enum system soon to be finished, then we will ask for feedback from you dear reader.
** Minor changes to the deployment tool, and qtpip
**QTBUG QLocale issue was found when using en_DE locale (fix was submitted)
** Working on the presentation for QtWS
**Android story is progressing well :D
** Continue the research for iOS support, it seems there are a few issues with the other frameworks that support it.
***Still figuring out wheel structure and testing
*** Distributing apps on iOS is tricky, it requires a Dev account ($$), with a free account you can only upload the app with a cable for 7 days, and then it expires (We wonder what would happen with data)
**Sample binding example of QObject classes as base
*** For uploading, you need to turn-on developer mode, which raises a message of "privacy being reduced"
**Continue with the PySide yocto cross compilation
*** iPad applications seems to have the same behavior.
** Might check https://github.com/benfogle/crossenv and https://github.com/beeware/mobile-forge
** PYSIDE-3059 was fixed
** PYSIDE-3012 was updated with new suggestions
** Free threading Python support continues PYSIDE-2221
*** A few changes we had for nogil are not necessary anymore.
*** Our mandelbrot example didn't show a good performance. After discussion with CPython core devs, there was an issue on Python 3.13.{1,2} (not on 3.13.0) that made some slowness. (On M1 it was 8x faster, but now it was 4.3x, the speed lost causes are still in research)

*** Optimization reviews: it seems it's only the virtual functions, but not the actual bindings.
** Size reduction: Windows is giving some issues for special characters, which seems to be also present in Linux.
** Cross compiling and creating wheels with the new JNI classes bindings. Trying to test them in an emulator, found other issues.
** pyside6-deploy/project and DS changes integrating, hopefully they will be merged today \o/

* Infra & Releases
** 6.8.2 will be released on 23th January so far, so we expect providing the wheels in the following days.
** 3.13 on the CI still on-going.
** 6.5.4 OSS released
* Bugs & Features
** Discussion about QJni* bindings when cross compiling.
*** It did built (and installed) for aarch64 and x86_64 but armv7a will be tried later on.
*** The main issue with this story was that it was bindings only for cross compiled pyside
** Exploring toml compatibilities within QtCreator
** DS patches still needs review.
** Binary size work continues
*** 17% reduction so far, and this could be included in the future-features list.
*** Once is ready, we might provide an option to disable it to go back to the more readable wrapper code.
*** We might evaluate a template approach once the solution is out, to avoid maintaining regexes.
** Remote Object reviews ready in order to merge changes (only a few details)
** Qt Python Scripting
*** Multiple inheritance is not supported yet.

    • Free threading Python support continues PYSIDE-2221
      • A few changes we had for nogil are not necessary anymore.
      • Our mandelbrot example didn't show a good performance. After discussion with CPython core devs, there was an issue on Python 3.13.{1,2} (not on 3.13.0) that made some slowness. (On M1 it was 8x faster, but now it was 4.3x, the speed lost causes are still in research)
