v2.062

  Big change for this release:
    * cme command is no longer delivered with this distribution. cme
      is now delivered by App::Cme distribution.

  To help the transition, this distribution delivers cme-old. You can
  use this command until App::Cme is available in CPAN (next few days)
  or if you find bugs in the new cme command (which now uses App::Cmd).

  Other incompatible changes:
	* old config-edit command is now really gone
	* cme extensions are obsolete. Extension mechanism is now provided
	  by App::Cmd

  New feature:
    * The Perl class used to implement node, list and hash
	  configuration element can be overridden using a new 'class'
	  parameter. The Perl class passed to this parameter must inherit
	  Config::Model::Node, or Config::Model::HashId or Config::Model::ListId.

  Bug fixes:
    * Value: skip notification if migrate yields an empty value
    * Model: use logger for tracing legacy translation
