+Changes from 1.20 to 1.30
+
+- Added size option to display size of duplicates. [LB, AL]
+- Added missing typecast for proper compilation under g++. [LB]
+- Better handling of errors occurring during retrieval
+  of a file's signature. [KK, AL]
+- No longer displays an error message when specified
+  directories contain no files. [AL]
+- Added red-black tree structure (experimental compile-time
+  option, disabled by default). [AL]
+
+Changes from 1.12 to 1.20
+
+- Fixed bug where program would crash when files being
+  scanned were named pipes or sockets. [FD]
+- Fix against security risk resulting from the use of a
+  temporary file to store md5sum output. [FD, AL]
+- Using an external md5sum program is now optional. Started 
+  using L. Peter Deutsh's MD5 library instead. [FD, AL]
+- Added hardlinks option to distinguish between hard links
+  and actual duplicate files. [FD, AL]
+- Added noempty option to exclude zero-length files
+  from consideration [AL]
+
+Changes from 1.11 to 1.12
+
+- Improved handling of extremely long input on preserve 
+  prompt (delete option). [SSD, AL]
+
+Changes from 1.1 to 1.11

-Frank DENIS aka Jedi/Sector One aka DJ Chrysalis <j@4u.net>:
-   - Provided patch to fix bug where program would crash when
-     files being scanned were named pipes or sockets.
-   - Warned against security risk resulting from the use of a
-     temporary file to store md5sum output. Suggested the use 
-     of RSARef instead of md5sum (author's note: used L. Peter 
-     Deutsch's MD5 message digest library instead of RSARef).
-   - Provided patch to fix problem where false duplicates would
-     be reported because of hard links. Unlike the symlinks
-     issue described in the documentation, these false
-     reports are not a threat to the data, just the link.
-     (author's note: modified patch for correctness).
