Our version 4.5 anniversary release is the most complex and feature packed ever. It affects Treepl's infrastructure, Treepl Portal, hosted mail integration, "BC to Treepl" app sync server, and the CMS itself. As you have noticed, we've started rolling out changes this Tuesday, and we will continue to do so during the next few days. Expect short breaks in site availability. If possible, changes and updates will be applied during the nighttime.
