I just noticed that the VTK 9.4.1 download hash sum has changed.
On 2025-01-08, the SHA512 sum was
```auto
CF83E1357EEFB8BDF1542850D66D8007D620E4050B5715DC83F4A921D36CE9CE47D0D13C5D85F2B0FF8318D2877EEC2F63B931BD47417A81A538327AF927DA3E
```
(I only recorded the SHA512 unfortunately).
Now the SHA512 is
```auto
F441953C4BEFDDA0AA2383810CDFA76CD510B275B14624DC6E56DA1C711598B9E003E4ACBD000171C43D6B8F1BCB2533391CE7D7542FD15B04CB5F9C62F38976
```
The SHA256 of the downloaded package matches the one listed on [https://vtk.org/download/](https://vtk.org/download/), so I’m not too worried; but was the package changed after release? I did not see any announcements about that.

Which file specifically ?
Where did you download it from ?

The .tar.gz, downloaded directly from [Download | VTK](https://vtk.org/download/), that is, via this link: [https://www.vtk.org/files/release/9.4/VTK-9.4.1.tar.gz](https://www.vtk.org/files/release/9.4/VTK-9.4.1.tar.gz).
I’ll check, I should still have the file that produced the other hash sum somewhere.

I found the file downloaded on January 8th, and it matches the current hash from [vtk.org](http://vtk.org).
So I must have somehow noted down the wrong hash sum.
Sorry for the confusion!!!

No worries 🙂
