     1.  If QUASAR crashes  and  must  be  restarted,  you  must  also
         restart  any  GALAXY  spoolers.   In addition, any BATCH jobs
         executing when  BATCON  must  be  restarted  should  also  be
         killed.

     2.  PS:<SPOOL>PRIMARY-MASTER-QUEUE-FILE.QUASAR, the master  queue
         file,  needs  to  be  deleted  when changing from a release 4
         GALAXY to a release 4.2 GALAXY since there has been a  change
         to  the  stored  queue  entries.  Also, if there is a need to
         revert to a previous version of GALAXY, the master queue file
         will  have to be deleted.  Note that this action also deletes
         all entries currently in the queue file.   In  addition,  all
         programs  that generate queue entries will need to be rebuilt
         with the new GALAXY.

     3.  The organization of GLXLIB has changed somewhat.  The  reason
         for  the  change  is  so that future changes will not require
         users to reassemble their  programs.   This  is  accomplished
         through the use of a new entry vector that is resolved during
         initialization.   The  impact  of  this  is  to  require  all
         programs  that  currently  use  GLXLIB to be reassembled with
         this release.  Any user programs that use GLXLIB will need to
         be reassembled.

     4.  Work was done in  several  of  the  spoolers  to  standardize
         OPERATOR  messages and the replies to those messages, Most of
         these messages now expect replies of ABORT or PROCEED instead
         of ABORT, PROCEED, CONTINUE, IGNORE, GO, REFUSE, etc.

     5.  The default time limits of a batch stream have been  changed.
         The  upper  limit  has  been  reduced  from  3600  to  a more
         reasonable maximum of 600 minutes.

                                                                Page 2


     6.  OPR and ORION are  built  with  NCP  entries  from  DECNET-20
         Version 2.1 which are the same as DECNET-20 Version 2.0.

     7.  DUMPER has been rebuilt with the GALAXY 4.2 universals.   But
         to run archiving an additional patch is needed.  Please apply
         the following patch to the version 4 DUMPER:

         @GET DUMPER
         @DDT
         QSRINT+5/  CALL RCVQSR    RETRY:
         QSRINT+14/ JRST QSRRET    JRST RETRY
         ^Z
         @SAVE DUMPER

         This allows DUMPER  to  process  multiple  IPCF  messages  at
         interrupt  level  if  the  last  message  received was a null
         message.

     8.  The EXEC, MOUNTR, and UETP/SENDER have been rebuilt with  the
         new  GALAXY  components.  These components will all have some
         version skew problems if an attempt  is  made  to  use  these
         components with a different GALAXY.

     9.  The EXEC must not be protected execute only.  If it is, BATCH
         jobs will fail.

    10.  Since NFT/FAL are provided under a separate license, they are
         not  contained  in  this  distribution.   But they need to be
         rebuilt using the new  GALAXY  universals.   See  the  DECNET
         documentation and control files for steps to rebuild NFT/FAL.
