This NEWS file records noteworthy changes, very tersely.
See the manual for detailed information.

   Important: in that version or later, the plugins "askpass-fifo",
   "password-prompt", and "plymouth" will no longer be run, since they
   would conflict with what cryptsetup is doing.  Other plugins, such
   as mandos-client and any user-supplied plugins, will still run.
** Better error message if failing to decrypt secret data
** Check for (and report) any key import failure from GPGME

** Bug fix: Fix systemd service file to start server correctly.
** Bug fix: Be compatible with old 2048-bit DSA keys.

   still works, but is deprecated.
* Client
** Can now find Mandos server even if the server has an IPv6 address
   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
   the PGP key.
** Bug fix: mandos-keygen now generates correct output for the
   "Checker" variable even if the SSH server on the Mandos client has
   multiple SSH key types.
** Can now use pre-generated Diffie-Hellman parameters from a file.

** If client host has an SSH server, "mandos-keygen --password" now
   outputs "checker" option which uses "ssh-keyscan"; this is more
   secure than the default "fping" checker.

   /usr/lib64/mandos.

Version 1.6.2 (2013-10-24)
* Server
** PID file moved from /var/run to /run.
** Bug fix: Handle long secrets when saving client state.
** Bug fix: Use more magic in the GnuTLS priority string to handle
   both old DSA/ELG 2048-bit keys and new RSA/RSA 4096-bit keys.
* Client
** mandos-keygen: Bug fix: now generate RSA keys which GnuTLS can use.
   		  Bug fix: Output passphrase prompts even when
   		  redirecting standard output.

Version 1.6.1 (2013-10-13)
* Server

Version 1.6.0 (2012-06-18)
* Server
** Takes new --foreground option
** Init script supports new "status" action.
* Client
** Now uses all interfaces by default; the --interface option can
   still be used to restrict it, and the argument to --interface (as
   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

Version 1.5.4 (2012-05-20)

* Server
** Removed D-Bus signal se.recompile.Mandos.NewRequest() added in

* Server
** Include intro(8mandos) manual page, missing since migration from
   README file in version 1.4.0.

* Client
** Network hooks.  The Mandos client can now run custom scripts to take
   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.
** Bug fix: Fix rare crash bug.
** Bug fix: Send corrent D-Bus type in PropertyChanged for
   "ApprovalDelay", "ApprovalDuration", "Timeout", and
   "ExtendedTimeout".

** New D-Bus signal: se.recompile.Mandos.NewRequest(s).

Version 1.4.1 (2011-10-15)
* Server
** Make D-Bus properties settable again, and handle checkers
   for disabled clients correctly.
* Miscellaneous fixes to "pedantic" Lintian warnings

Version 1.4.0 (2011-10-09)
* README file migrated to manual page intro(8mandos).
* Client:
** Fixed warning about "rmdir: Directory not empty".
* Server:
** Default values changed: timeout 5 minutes, interval 2 minutes.
** 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.

Version 1.3.1 (2011-07-27)
* Client:
** Client now retries all Mandos servers periodically.
** Work around Debian bug #633582 - fixes "Permission denied" problem.

* Server:
** Updated for Python 2.6.
* Client:

Version 1.2.2 (2010-10-07)
* Client:
** splashy: Minor fix to compile with non-Linux kernels.

Version 1.2.1 (2010-10-02)
* Server:
** mandos-monitor(8): Documentation bug fix: Key for removing client
   is "R", not "r".

Version 1.2 (2010-09-28)
* Client:
** New "plymouth" plugin to ask for a password using the Plymouth
   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".
** New control utilities using the new D-Bus API:
   + mandos-ctl		       A command-line based utility
   + mandos-monitor	       A text-based GUI interface
** New feature: manual interactive approval or denying of clients on a
   case-by-case basis.
** New --debuglevel option to control logging
** Will not write PID file if --debug is passed

   its config files (with encrypted passwords) into the initrd.img-*
   files.

Version 1.0.12 (2009-09-17)
* Client
** Bug fix: Allow network interface renaming by "udev" by taking down
   the network interface after using it.
** Bug fix: User-supplied plugins are now installed correctly.
** Bug fix: If usplash was used but the password was instead provided
   by the Mandos server, the usplash daemon used to ignore the first
   command passed to it.  This has been fixed.
** Bug fix: Make the "--userid" and "--groupid" options in
   "plugin-runner.conf" work.
* Server
** Bug fix: Fix the LSB header in the init.d script to make dependency
   based booting work.

   run successfully (i.e. the timeout timer is reset).
