+This Director and Storage daemon must be upgraded at the same time,
+but they should be compatible with all 2.0.x File daemons, unless you
+use some of the new features that affect the FD. In other words, you should
+not have to upgrade all your File daemons. However, bat works only with
+a 2.1.8 Director.
+
+Areas requiring caution or testing:
+- You must have Qt4 Version 4.2 or greater loaded to build bat
+- You must have the thread safe version of MySQL client libraries loaded
+ to build with MySQL enabled.
+- The Volume management in the Storage daemon is extensively rewritten.
+ It appears to function much better, but is largely untested under
+ severe stress conditions (multiple drive autochangers, ...).
+- Volumes are pruned only when absolutely necessary -- this may cause
+ your database to grow.
+- Socket level heartbeat is untested.
+- Solaris door and even port files are no longer restored (equivalent
+ to what we do with sockets).
+- Solaris is untested
+- Win32 servers are untested, and very likely not to work.
+
+The major new features are:
+- Much faster insertion of attributes (somewhere around 10 times),
+ many thanks to Eric Bollengier and Marc Cousin.
+- First cut of bat (Bacula Administration Tool). Note to build
+ bat you must explicitly enable it on the ./configure line, you
+ must have the Qt4 version 4.2 or later libraries loaded, and
+ qmake and the other Qt4 tools must be available. bat is ALPHA
+ software. A large part of the work was done by Dirk Bartley.
