-Upgrading to 4.0
-----------------
-
-If you are upgrading from a version of OfflineIMAP prior to 3.99.12, you will
-find that you will get errors when OfflineIMAP starts up (relating to
-ConfigParser or AccountHashGenerator) and the configuration file.  This is
-because the config file format had to change to accommodate new features in 4.0.
-Fortunately, it's not difficult to adjust it to suit.
-
-
-First thing you need to do is stop any running OfflineIMAP instance, making sure
-first that it's synced all your mail.  Then, modify your `~/.offlineimaprc` file.
-You'll need to split up each account section (make sure that it now starts with
-"Account ") into two Repository sections (one for the local side and another for
-the remote side.)  See the files offlineimap.conf.minimal and offlineimap.conf
-in the distribution if you need more assistance.
-
-
-OfflineIMAP's status directory area has also changed.  Therefore, you should
-delete everything in `~/.offlineimap` as well as your local mail folders.
-
-
-When you start up OfflineIMAP 4.0, it will re-download all your mail from the
-server and then you can continue using it like normal.
