ParaView currently does not build against Qt 5.12, which was end-of-lifed in 2021. We are planning to make the minimum 5.15 for ParaView 6.1. Please let us know if that causes any difficulties.

**Update:** In ParaView 6.2, support for Qt 5 will be [dropped altogether](https://discourse.paraview.org/t/qt-5-support-to-end-starting-in-paraview-6-2/17365).

Side question, is there a list somewhere of Paraview dependencies and their minimum versions? Thanks.

Was Qt 5.15 end-of-lifed earlier this year? I would be curious how many systems get cut out of the minimum Qt version jumps to 6.x.
