Notes from the meeting today:
## VTK regressions (Sam)
VTK pushed a very small but very breaking change in minor version (removing a transitive include of iostream), which broke a lot of extensions. We have been working through the extensions – the fix is very simple.

> Fix log (unchecked are in progress): SlicerDMRI SlicerRT : [Iostream missing include fixes by sjh26 · Pull Request #314 · SlicerRt/SlicerRT · GitHub](https://github.com/SlicerRt/SlicerRT/pull/314) MeshToLabelMap SlicerVMTK: Pending this vmtk fix, [Include iostream to build against VTK 9.6 by chir-set · Pull Request #481 · vmtk/vmtk · GitHub](https://github.com/vmtk/vmtk/pull/481), my branch here: [GitHub - sjh26/SlicerExtension-VMTK at fix-iostream · GitHub](https://github.com/sjh26/SlicerExtension-VMTK/tree/fix-iostream) VASSTAlgorithms: [BUG: Add missing #include \ to C++ files using cerr/endl by sjh26 · Pull Request #5 · VASST/V…](https://github.com/VASST/VASSTAlgorithms/pull/5)
## Qt6 status
Steve rebuilt mac arm64 build and there didn’t seem to be any issues this time, except that a dialog box didn’t seem to allow discarding without saving.
## Telemetry (Ebrahim)
Service is now deployed at [slicer-telemetry.kitware.com](https://slicer-telemetry.kitware.com/).
## Work on developing a claude skill to summarize extension error (Sam)
