Added new 'Message Store Operation' action. This action can be used to return a conversation. A conversation is a transcript of message store messages between two email addresses with the same subject. The list can be returned in Markdown, JSON, CSV or HTML format. The Message Store Operation action can also be used to drop the current message (preventing it from being saved in the message store) and to drop a conversation.
Added a tag entry to Knowledge Store articles. The tag can be any text. You can now return the top tag and top title to %variables% when you do a search.
Added %Msg_Importance% and %Msg_ConversationId% built-in variables.
The 'Return' action now has the option to not save the return value with the message in the message store.
The Studio preferences now has an option to disable the confirmation message when deleting actions.
Added App-Only access option for Microsoft Office 365 logins. This allows for client-credentials login.
