        User visible changes of this version since 1.4:

- Ethernet device emulation is available (--enable-protocol=4).
  New options mask, bcast, hwaddr to set device parameters in this case.
- The first, limited capability version of the PKCIPE package has been 
  integrated.
- The sample ip-up and ip-down scripts have been changed for PKCIPE.
  If you use PKCIPE, you have to port these changes to your local scripts.
- Absolute maximum of supported channels increased to 10000, but only with
  dynamic channel allocation (default).

        User visible changes of this version since 1.3:

- IMPORTANT: A necessary bugfix in ciped causes keys to be incompatible
  with earlier versions unless special precautions are followed.
  See README.key-bug for details.
- C version of Blowfish available.
- Runs under Linux 2.3.x, at least with x>=48.
- Option files have to be given as absolute paths.
  More strict permission checking on these files.

     	User visible changes of this version since 1.2:

- Build uses an autoconf script. Poking around in the Makefile is
  unnecessary now. Installing: ./configure; make.
  Options are set on the command line of ./configure.
  configure script looks for kernel headers in default location.
- Compilation happens in separate object directory, it is possible to
  have different configurations (e.g. IDEA/Blowfish) at once in
  different object directories.
- ciped has been renamed to ciped-XY, with XY as in cipXY.o.
- ip-up, ip-down get passed the configuration parameters in environment.
- Options to send internal keepalive pings and timeout on them.

	User visible changes of this version since 1.0:

- Runs under Linux 2.1.x, at least with x>=109, and 2.2.x.
- Device names have changed: protocol version is now a letter. 1=a,
  2=b etc., so cip3b->cipcb.
- Channels are allocated and deallocated dynamically. This enables the
  default for cipe_maxdev to be set to 100.
  (Compilation option NO_DYNDEV to remove this feature.)
- Statistics are logged upon close and then cleared. The log is simply
  one line from /proc/net/dev.
- ciped waits for completion of ip-up before daemonizing.
- New configuration option for using key exchange timestamps.
