== Special Notes for this Release ==

== Features Introduced in This Release ==

=== General ===

  * Configuration file persistence
    * When installed to disk (using {{{sysinst}}}), HelenOS can now hold persistent configuration (in {{{/w/cfg}}})
    * It is possible to deliver initial configuration files (in {{{/cfg}}})

      * Network configuration (IP addresses and routes)

=== Kernel ===

=== User Interface ===

  * The system can now be shut down
    * using the Shut Down dialog
    * or using the command-line {{{shutdown}}} command
    * (previously the user would have to manually eject volumes and remove power)
  * In console (non-GUI) mode switch virtual consoles using Alt-Fn or Shift-Fn
    * Originally just Fn was used, which prevented Fn to be used by applications
