Bugfixes:
The date on the file preview of an email thread was incorrect in our soon-to-be-released enhanced email feature, during internal testing.
During internal testing, when the root folder was set to the root of a document library/drive, the word 'root' appeared instead of the name of the document library in the Sharepoint folder picker.
When an email file was previewed in the Knowledge Base, the padding around the content in the left-hand panel was insufficient.
