We are happy to announce the fifth release candidate of the 1.4.0 version of dnsdist. This release fixes a regression introduced in DNS over HTTPS handling in 1.4.0-rc4 that could lead to a crash under heavy load, because of a race condition.
The issue was reported during load-testing by one of our users a few hours after the release and we were able to issue a fix during the week-end. We quickly advised DNS over HTTPS users to delay upgrading for a bit, and after exposing the resulting code to various tests during a couple days we are now confident that the issue has been resolved.
We want to thank everyone that contributed to the testing of the previous release candidates, and invite you to contribute to the testing of this hopefully last one!
Release tarballs are available on the downloads website.
Several packages are also available on our repository.
