Current versions of Signature 365 software
The Signature 365 client-side add-ins are updated on a frequent schedule; current versions of all client-side deployments are listed below.
If deployed from using the Get-Addins option from the Microsoft admin centre, the modern add-in will update itself when released. Manifest changes will display "Upgrade Available" in the integrated apps portal when a manifest update is available.
If manually deployed via XML, the modern addin will in most cases automatically update but will require manual updating following a manifest version change to implement new features. Information on manifest updates will published by Symprex.
Information on the manual update process can be found here.
The classic and mac agents are installed directly on devices, and cannot be updated automatically; these must be downloaded and installed on any devices they are installed on.
Our Exchange agent, Active Directory and Database connectors must all be installed manually. Updates to the connectors are rarely required, but will preserve all existing settings on update.
Updates can be installed without removing the existing version, and will replace the previous version unless noted below.
