* Server

** Bug fix: Handle local Zeroconf service name collisions better.

   on a network without IPv6 Router Advertisment (like if the Mandos

   client itself is the router, or there is an IPv6 router advertising

   a network other than the one which the Mandos server is on.)

** Use a better value than 1024 for the default number of DH bits.

   This better value is either provided by a DH parameters file (see

   below) or an appropriate number of DH bits is determined based on

   		  Bug fix: Output passphrase prompts even when

   		  redirecting standard output.

Version 1.6.1 (2013-10-13)

* Server

** All client options for time intervals now also take an RFC 3339

   duration.  The same for all options to mandos-ctl.

   well as the $DEVICE environment variable for the network hooks) is

   now a comma-separated list of interfaces to use.

Version 1.5.5 (2012-06-01)

* Server

** Server takes new --socket option

   up a network interface before the client is run.  Three example

   scripts are provided: "wireless", "openvpn", and "bridge".

   To facilitate this, the client now prefers network interfaces which

   are up (if any) over all other interfaces.

* Server

** Persistent state.  Client state is now saved between server

   restarts.

** clients.conf file can now contain "enabled" setting for clients.

** Clients gets an expiration extension when receiving a password,

   controlled by new "extended_timeout" setting.

** New domain name: "fukt.bsnet.se" changes to "recompile.se".  This

   also affects the D-Bus bus and interface names (old names still

   work).  Users should start using the new names immediately.

** New D-Bus Client object properties "Expires" and "ExtendedTimeout";

   see DBUS-API for details.

   graphical boot system.

** The Mandos client now automatically chooses a network interface if

   the DEVICE setting in /etc/initramfs-tools/initramfs.conf is set to

   the empty string.  This is also the new default instead of "eth0".

** The Mandos client --connect option now loops indefinitely until a

   password is received from the specified server.

** Bug fix: Quote directory correctly in mandos-keygen with --password

** Bug fix: don't use "echo -e" in mandos-keygen; unsupported by dash.

* Server:

** Terminology change: clients are now "ENABLED" or "DISABLED", not

   "valid" or "invalid".

** New D-Bus API; see the file "DBUS-API".
