 +0.7.3 (to be announced) "weighted correctness"
 +----------------------------------------------
 +
 +- Old style PEM keys are now deprecated. They still work but their
 +  use results in a run-time warning. The removal of PEM key support is
 +  scheduled for paraslash-0.8.0.
 +- Version 1.0 of the openssl library has been deprecated. A warning
 +  is printed at compile-time on systems which have this outdated version
 +  because it will no longer be supported once paraslash-0.8.0 comes out.
 +- A spring cleanup for the senescent code in fd.c.
 +- The --admissible option of the ls command now takes an optional
 +  argument. When invoked like --admissible=m/foo, only files which are
 +  admissible with respect to mood foo are listed.
 +- The select server command is now quiet by default, The new --verbose
 +  option can be used to show information about the newly loaded mood
 +  or playlist.
++- The ls server command gained the --limit option to force a limit
++  on the number of files listed.
