Based on some changes upstream in the 3d rendering library we use, we're looking to bump the minimum supported Java version from Java 8 to Java 17. Looking for feedback from our users on if this would be a huge imposition, we could with some additional work restore the Java 8 compatibility but I'm hoping that we can just move forward a bit here.

Feedback appreciated!

For me, it wouldn't have an impact. I currently use OpenJDK 25 (Java 25). In general, if it’s an improvement, I think it’s a good thing. However, it’s also important to check if anyone is using it with Java 8. Thank you very much!

Atenciosamente,

I should also mention this is to support future Java version > 25 (currently we error on java 26 and 27 with the removal of the Applet code) this update would raise the minimum version to 17, and enable Java 26 and beyond.

Cheers,

Harvey

Ditto for me. No issue and, like Cristiano, I'm using 25 in my local builds.

Hi. By chance I downloaded yesterday your 2026-07 release, then I had to upgrade Java, no problem - unless something I'm facing now is due to this change: I drag objects into a SubModel Region and this doesn't work, they are not created inside the SubModel, but as independent objects ¿? I'll try to find out why, or since when this is happening (this is why I've just entered the forum and seen your question).
