Notes from the meeting:

## Qt6 Support

- James starting to succesfully build with Qt6 across platforms now
- Should Qt be an external project, now that it uses cmake? There are good and bad aspects to this…
- Given the [Qt support schedule](https://endoflife.date/qt), which version of Qt6 are we going to support? Maybe 6.11 is what we will roll out with.

## MacOS test failures

- [Dashboard link](https://slicer.cdash.org/builds/4062294/tests?filters=%7B%22all%22%3A%5B%7B%22eq%22%3A%7B%22status%22%3A%22FAILED%22%7D%7D%5D%7D)
- Dec 19 or so is when those started failing. May be related to the ITK [changes introduced to support reading 2D transforms](https://github.com/Slicer/Slicer/pull/8842). It may have to do with the floating point precision changes from that work.

## Factory machines

- After Qt6 the next big project will be arm system support. We already have the factory machine
- metroplex, the linux build machine, is pretty old and slated for replaement
- We are trying to bring in another windows factory machine to take the load off bluestreak.

## SimpleITK crash on linux

- [#8947](https://github.com/Slicer/Slicer/issues/8947)
- We should have Brad add the namespace, since this would be a minimal change and potentially be the easiest fix. And less unnecessarily risky than the option of removing a bunch of infrastructure.
