Kopano One – Week 3 updates
The first update to the Kopano One repositories includes new versions of Kopano Webapp and Z-Push.

Kopano WebApp 4.7.0
In this release we made various improvements and bugfixes to our OIDC implementation. We've also updated the DOMPurify library and disabled MathML in combination with DOMPurify, due to many reported security issues in this library. MathML was never supported by WebApp, so we were not affected.

Z-Push 2.6.1
This maintainance release includes some bug fixes and improvements. The issue with duplicate attendees in Outlook should be fixed. Deleted properties of a contact are now correctly picked up by the gab2contacts script. Michele contributed state files' write improvements on busy systems.
