A new release of webtrees is available.
It contains a fix for a serious security issue. YOU SHOULD UPGRADE AS SOON AS POSSIBLE.
I would like to thank
Boris Unckel
for finding the issue, and reporting it responsibly.
If you participate in any other webtrees forums, please could you post this message there.
