-
-loadbars (0.6.0.5) stable; urgency=low
-
-  * Introducing network stats. Network stats toggle button is 3
-    The new --netint INTNAME startup param specifies the nic to observe.
-    The new --hasnet 0|1 startup params specifies whether to display network 
-    stats on startup. 
-    The new --netlink SPEED startup params specifies the network interface 
-    speed to assume on startup on the given nic. Possible values are mbit,
-    10mbit, 100mbit, gbit, 10gbit or just a number which is interpreted as 
-    mbytes/s. If no --netlink param is given the standard NIC speed is set to
-    1gbit.
-
-  * Incoming network traffic is displayed from a bar coming from upside down 
-    (light green). 100% means: The theoretical network bandwidth is used 
-    100%.
-
-  * Outgoing network traffic is displayed from a bar coming from downside up 
-    (light green). 100% means: The theoretical network bandwidth is used 
-    100%.
-
-  * Rxb means: Received bytes in % until total bandwidth
-
-  * Txb means: Transmitted bytes in % until total bandwidth
-
-  * During runtime the v hotkey decrease the link speed by factor 10
-
-  * During runtime the f hotkey increases the link speed by factor 10
-
-  * During runtime the n hotkey switches to the next available network
-    interface. If you have hosts with different nics and try to switch to a
-    nic wich is available on one host but not on another a *big red* bar will
-    be shown on the host which is missing the specific nic.
-
-  * Memory stats toggle button is now 2 instead of m. If you press m a
-    deprecation massage is shown and nothing more happens.
-
-  * Some code optimizations on CPU bars. It should consume *at least a little*
-    less CPU on the display host than before. BUT NOT *much less*!
-
-  * New manual page (removed some infos from --help and put it into the 
-    manpage).
-
-  * Removed the --factor switch, since it was barely used and caused some 
-    implementation details on network and memory stats. Maybe I am just too 
-    studpid.
-
-  * Improved the info messages displayed on stdout.
-
-  * The remote code (fetching infos from /proc fs) is now written in perl and 
-    not bash anymore. Sooner or later this will be used to put more logic into
-    it (e.g. setting uptime intervals separately for differend kinds of stats).
-
-  * Re-add the --title startup params which specifies the window title of the
-    loadbars session.
-
-  * Some code refactoring.
-
-  * New wishlist brainstorming for next released (see docs/wishlist).

-loadbars (0.5.3) stable; urgency=low
-
-  * Introduce new param --hasagent. With --hasagent 1 loadbars will not
-    run 'ssh-add' which would ask for your SSH key password to add it to 
-    the ssh agent. With --hasagent 0 (default value) loadbars will run
-    'ssh-add' on startup in order to add your SSH key to the SSH agent.
-
-  * Add openssh-client dependency to the .deb package.
-
-  * Some code bugfixing.

-    So --cluster clusterB will connect to server01 server02 and server03 
-  * --hosts option supports username to be specified. E.g.:
