This file  is an  addendum to  the original  description of  changes from
release 1.6b to  1.6c. In order to obtain the  current description of the
changes  from  release 1.6b  to  1.6c,  you  should search  the  LSTSRV-M
archives for all items with a subject starting with "Changes from Release
1.6b to 1.6c".

Releases
affected    Description of the problem
--------    --------------------------
  All       Infinite loop  in LSVDIST2 for  some (rare) types  of invalid
            RFC822 headers. Fixed.
 
  All       LISTSERV fails to logoff if spool becomes full while DIST2 is
            in progress, causing possible loss of data. Fixed.

* Recovery Enhancement: Updates to R/O copy of BITEARN NODES *
**************************************************************
 
>With release 1.6c, the minidisk  containing BITEARN NODES is re-accessed
>every time the  file needs to be  read, unless it is a  R/W minidisk (in
>which  case  this would  be  superfluous)  or  it  is accessed  with  an
>extension mode  (as in 'ACCESS  1A3 C/C * NODES  C' - LISTSERV  does not
>know  which  files  were  originally selected,  and  can  therefore  not
>re-ACCESS the disk in a transparent way).
 
For  minidisks accessed  with  an  extension mode,  a  user  exit can  be
provided by the installation to  execute the necessary command. This exit
must be named  LSV$ACCx (where 'x' is  the mode of the  disk in question)
and contain the  required ACCESS command. In the  above example, LISTSERV
would look for a LSV$ACCC EXEC and, if found, call it rather than display
an error message; this exec could contain the following 3 lines:
 
/* User-exit to re-access our local C-disk */
Address '' 'ACCESS 1A3 C/C * NODES C'
Exit rc

* Documentation: Minor changes to Installation Guide *
******************************************************
 
Minor  changes have  been made  to the  Installation Guide,  in order  to
update the list of supported  operating system components, to reflect the
new  recommended  storage  size  of  3M, etc.  Since  these  changes  are
irrelevant  to sites  already running  LISTSERV, the  2268-lines LISTINST
MEMO will not be included in the release 1.6c update shipment.
 
Additionally, some  changes have  been made to  the License  Agreement to
reflect the present status of the availability of LISTSERV to EARN sites.
Although these changes  are irrelevant to sites which  already obtained a
free license, for legal reasons any  update to the License Agreement must
be notified to the recipient of  the license, and there will therefore be
an updated LISTCPRT MEMO in the release 1.6c shipment.
