+* 2.0 -> 2.1
+
+** Authentication
+
+Users are now stored in the database rather than in 'allow' directives in a
+private configuration file. 'allow' is still understood in this version, but
+is only used to populate the database on startup. After the first (successful)
+run of the server the remaining 'allow' directives should be deleted.
+
+'restrict' and 'trust' are replaced by a system of per-user rights. The
+default user rights are based on the 'restrict' setting, and the rights of
+users created frow 'allow' directives preserve the meaning of 'trust', but
+after the first run you should remove these directives and (optionally) add a
+'default_rights' directive.
+
+'allow', 'restrict' and 'trust' will stop working entirely in a future version
+but for now they will generate harmless error messages. Remove them and the
+error messages will go away.
+
+** Other Server Configuration
+
+Sensible defaults for 'stopword', 'player' and 'tracklength' are now built into
+the server. If you haven't modified the values from the example or Debian
+configuration files then you can remove them.
+
+'gap' now defaults to 0 seconds instead of 2.
+
+** Web Interface
+
+The web interface no longer uses HTTP basic authentication and the web server
+configuration imposing access control on it should be removed. Users now log
+in using their main DisOrder password and the one in the htpassed file is now
+obsolete. You should revisit the web interface setup instructions in README
+from scratch.
