I tested this update by installing evolution 3.22.6-0ubuntu0.1 on Ubuntu GNOME 16.10. I restarted. I opened Settings>Online Accounts (this is GNOME Settings, not Evolution Settings) and added my Google account. I then opened Evolution. My Google Calendar and Contacts synced successfully. My email synced successfully with IMAP. I was able to open plain text and HTML emails. And I sent a test email from Evolution that I received successfully in another account outside of Evolution.
