+Dirdiff now also has a file mode, which can be used for viewing the
+differences between files and for merging changes from one file into

+What's new in dirdiff-2.1.
 --------------------------
 
-* The help text and Makefile have been updated, thanks to Martin Pool.
+* The diff display window can now display 3-way, 4-way and 5-way diffs
+  as well as the normal 2-way diffs.  When a line is identified as
+  coming from multiple files, most of it will be colored for the
+  newest of those files, and extra colored bars at the left of the
+  line will identify which other files it is in.
+
+* You can now modify the diff display interactively (for example, to
+  make it more understandable).  You can use the middle mouse button
+  to drag the blue separator bars to expose more context, or drag
+  colored diff lines up and down (the movement is constrained so as to
+  not alter the meaning of the diff).  Dragging context lines splits
+  them into colored diff lines.
+
+* There is now a menu on the diff display window for generating
+  patches embodying the changes that could be made with the merge
+  menu.  That is, the diff lines that are checked in the diff viewer
+  will be made into - and + lines in the generated patch.
 
+* The BitKeeper integration feature has been removed.  I plan to add
+  generic features for integration with arbitrary SCM systems in
+  future.

+What was new in dirdiff-2.0.
 ----------------------------
 
-* Dirdiff can now generate a patch containing the differences in a
-  selected set of files between any two directory trees.  See the
-  File -> Make patch submenu in the main window.
+* Some great new features from Dorothy Robinson:
+
+  - A dialog box for choosing the directories to be diffed, if dirdiff
+    is invoked without specifying any directories or files on the
+    command line.
+
+  - Colored icons instead of squares in the file list window.
+
+  - Colored icons in the Diff and Copy/Del menus (provided you are
+    using Tk 8.4 or later).
+
+  - Modifications so dirdiff can be used under Windows.
+
+  - A color key showing the ordering of the colors.
 
-* Some key bindings have been fixed.
+  - Use of two-level menus for the Diff, Copy/Del and Patch menus (the
+    Diff and Copy/Del menus use two levels only when there are
+    sufficient alternatives for it to make things simpler).
 
-* The results of a merge are now put into a window where it can be
-  inspected and edited, rather than immediately replacing the original
-  file.
+  - A filename search function using the filename bar in the file list
+    window.
 
-* There is now a find function which can be used in the differences
-  window, the merge window and the patch window.
+  - Options to allow the user to select external diff and file viewer
+    programs.
 
-* Various bugs have been fixed.
+* There is now a mode for ignoring files in a directory if they match
+  any of the patterns listed in the .cvsignore in that directory.
+  This is invoked with the -C command-line option or by choosing the
+  "Ignore files in .cvsignore" option in the Options menu.
+
+* Some users have requested a mode in which, when a directory exists
+  in one tree but not another, dirdiff display the files in that
+  directory as existing in the one tree but not the other (rather than
+  displaying just a single line for the directory).  This mode is
+  enabled by choosing the "Show files that aren't in some dirs" option
+  in the Options menu.
+
+* Trees can now be marked as "read-only" in the Options menu.  This
+  means that menu options that would modify those trees (in the
+  Copy/Del, Touch and Merge menus) will not be offered.
+
+* Files can be added to the excluded file list by selecting them and
+  choosing "Exclude selection" under the File menu.
+
+* Changes to the "Underline tabs" mode now take effect immediately.
