The Revive Adserver team is proud to announce the immediate availability of Revive Adserver v5.2.1.

Revive Adserver logoWe are pleased to announce the release of version 5.2.1 of the Revive Adserver software. This version contains several improvements, and fixes a bug and a low risk security issue.

Here is a list of improvements in Revive Adserver v5.2.1:

  • We added a security check in the admin UI that verifies upon login and on demand if the browser can access files that should be forbidden, eventually prompting the admin to fix the potential security problem.
  • Several major languages were missing from the Client Language delivery rule: the list has been revised and updated.

We fixed a bug in this version 5.2.1 of Revive Adserver:

  • We fixed an issue preventing clicks from redirecting to the destination URL on newsletter zones.

Full release notes for v5.2.1 can be found on our Github page.
