- * Add a preliminary Macintosh package (ticket #182).

- * Add more measurements of performance:
-   http://allmydata.org/trac/tahoe/wiki/Performance .
+This release adds extensive "visibility into the grid" -- the web user
+interface now shows detailed information about the nodes comprising
+the grid and fine-grained statistics about the time and space used for
+the storage and retrieval operations.
 
- * Add an upload helper, with resumption of incomplete uploads and
-   short-circuiting of uploads if the file is already present (tickets
-   #116, #258, #218).
 
- * Make upload continue even if some servers disappear during the
-   upload process.
+Since v0.8 we've made the following changes:
 
- * Add mtime and ctime timestamps to files (ticket #183).
+ * Added user-friendly Windows application and package, thanks
+   especially to Rob Kinninmont and Mike Booker (tickets #195, 242,
+   243, 321, 335).
 
- * Make introduction more efficient by allowing nodes to act as
-   clients-only and not publish themselves as servers (ticket #271).
+ * Display information about uploads and downloads (ticket #39).
 
- * Extend the web API to allow programmatic control of mutable files.
+ * Improve performance (including tickets #304, 321).
 
- * Fix potential problem that could cause corruption of downloaded
-   mutable files if a long series of unlikely coincidences and hacked
-   clients occurred (ticket #312).
+ * Improve packaging and testing (including ticket #145).
 
- * Make file and directory names use unicode.
+ * Add even more extensive automated tests (including ticket #207).
 
- * Use SHA-256d instead of SHA-256 for secure hashes.
+ * Updated documentation.
