after not being able to run ioquake3 today, i went to their webiste (www.ioquake3.org) and found this link to a security notice i wish to pass on --- ioquake3.org/2019/...ly-compromised/

Thanks heaps for the heads up about the possible issue with the test builds of ioquake3.

This issue is restricted to the overnight test builds only. If you download the "official releases" from ioquake3.org/get-it/ - there will be no issue.
