The release page references a opencascade-dataset-7.9.2.tar.xz which does not exist.
The dataset released with V7_9_0_beta1 doesn't work for all 7.9.2 tests.

[dpasukhi]

Thank you for report.
The dataset is not changed since 7.9.0. Maintenance version is not updates test file base.
I will update link to previous used to avoid 404.
The new dataset will be published only for 8.0.0 in February or later.

Public dataset is significantly smaller compared to our internal, which is not publicly available.

I try to run draw.bat, but it failed and said dlls not found. It's due to the absolute 3rdparty path in env.bat at line #135 . I change it to

if ["%THIRDPARTY_DIR%"] == [""] set "THIRDPARTY_DIR=../3rdparty-vc14-64"

It runs well again

[dpasukhi]

Can you share a package name with that problem?

[a-ciue]

It's occt-combined-with-debug-pch.zip. And I haven't try any other packages yet.

[dpasukhi]

Oh, it is only issue for "with-debug", my apologies. During a week packages will be updated
