 ### Release Notes
 
+This is a preview and test release for version 1.1.
+
+A few new features have been added. The primary change is that the project tree on the left side of
+the main window now has two tabs. The regular project tree is now on a tab named "Project", while a
+new tab "Novel" displays a simpler version of the information on the main "Outline" page. It lists
+all the headers of the novel part of the project, as well as the word count and point-of-view
+character of each section. This is an alternative way to navigate the novel part of the project.
+The various tree views are now also kept better in sync when the user selects various documents and
+headers.
+
+In addition, a new information dialog named "Project Details" has been added. It replaces the
+"Details" tab in "Project Settings", and adds more information about the novel part of the project.
+In particular, a "Table of Contents" in the "Contents" tab displays a summary of the main parts
+and chapters of the project, their total word counts, and an estimated page count. This was made in
+response to users asking for ways to estimate the total page count of the project. The page count
+is estimated based on the word count, and can be changed on the dialog window.
+
+Since the tabs below the project tree now adds some extra room on the GUI, some convenient buttons
+have been added, with direct access to "Project Details", "Writing Statistics" and "Project
+Setting".
+
+A few other minor changes have been made as well. The Preferences dialog has been improved with
+clearer categories and hopefully better help text. Some new options have been added too. They allow
+syntax highlighting of multi-paragraph quotes. The highlighter can now optionally accept quotes to
+be left "hanging", that is, no closing quote in the same paragraph.
