-Minor Changes
-'''''''''''''
-- minor: #1355, #1366, #1388, #1389, #1391, #1297, #1342, #1404, #1392,
-  #1412, #1344, #1345, #1347, #1334, #1274, #1438, #1120, #1359, #636, #1469,
-  #1149, #1441, #1503, #1510, #1507, #1505
-- minor SFTP fixes: #1442, #1446
-- finish .rst-ifying all docs
-- shuffle configuration.rst to add Frontend section
-- add man page #1420
-- IServer refactoring #1363
-- Nodes now emit "None" for percentiles with higher implied precision
-  than the number of observations can support. Older stats gatherers
-  will throw an exception if they gather stats from a new storage
-  server and it sends a "None" for a percentile. (`#1392`_)
-

-Compatibility and Dependencies
-''''''''''''''''''''''''''''''
-
-- An incompatibility of zope.interface version 3.6.4 with Nevow has
-  been resolved. Tahoe-LAFS now requires one of the exact versions
-  v3.3.1, v3.5.3, or v3.6.1 of zope.interface. (`#1435`_)
-- The Twisted dependency has been raised to version 10.1. This ensures
-  that we no longer require pywin32 on Windows, and that it is never
-  necessary to patch Twisted in order to use the FTP frontend.
