What's new in this patch?
Our last update to Web ADI for EBS 12.1 and 12.2 renewed the digital certificates that were valid to August 2018.
A new SHA-256 digital certificate is now available for EBS 12.1.3 and 12.2.3 (and later 12.2 releases). This new patch will prevent security alert warning messages from being displayed in Microsoft Office. The new digital certificates are valid through February 2020.
