> Mailing Lists
> --------------------------------------------------------
>
> NAIF has created 2 mailing lists, ``Spice_announce''
>
> http://naif.jpl.nasa.gov/mailman/listinfo/spice_announce
>
> and ``Spice_discussion''
>
> http://naif.jpl.nasa.gov/mailman/listinfo/spice_discussion
>
> ``Spice_announce'' is intended to provide notification of important
> developments such as a new toolkit release. Posting will generally be
> limited to members of the NAIF team. If you feel you have an important
> announcement that would be suitable for this list, you may send email
> to the list, but it will be reviewed by the NAIF team before
> dissemination.
>
> ``Spice_discussion'' is meant to provide a forum for discussion among
> SPICE users. Posting on this list is encouraged, however we also
> encourage you to limit mail traffic to the entire list. Extended
> discussions are often best carried out with a limited distribution
> list.
>
> Both lists require registration, allow access to an archive of prior
> postings and allow the user to choose whether to receive individual
> postings or a daily digest.
>
>
> Environments
> --------------------------------------------------------
>
> The N0054 version of the SPICE Toolkit is supported on the same
> environments as version N0053.
>
>
> COOKBOOK Programs
> --------------------------------------------------------
>
> FORTRAN and C versions of the COOKBOOK programs have been made more
> consistent in implementation and behavior. User's Guide documents for
> COOKBOOK programs have been updated and are now delivered with both
> FORTRAN and C toolkits. The FSTSPK COOKBOOK program has been
> deprecated and is no longer delivered.
>
>
> New Built-in NAIF ID Code/Name Definitions
> --------------------------------------------------------
>
> The following new built-in NAIF ID code/name definitions have been
> added to the toolkit:
>
> Spacecraft:
>
> -226 ROSETTA
>
> Jovian satellites:
>
> 517 CALLIRRHOE
> 518 THEMISTO
> 519 MAGACLITE
> 520 TAYGETE
> 521 CHALDENE
> 522 HARPALYKE
> 523 KALYKE
> 524 IOCASTE
> 525 ERINOME
> 526 ISONOE
> 527 PRAXIDIKE
>
>
> Documentation
> --------------------------------------------------------
>
> User's Guide documents for TOBIN, TOXFR and VERSION utility programs
> have been added to the toolkit documentation.
>
>
> Bug Fixes
> --------------------------------------------------------

>
> Built-in Body-Fixed Frame for Pan
>
> Definition of the built-in body-fixed frame for PAN (IAU_PAN) has been
> updated to point to the correct PCK values used to compute its
> rotation. In the previous version of the toolkit it was pointing to
> PANDORA's rotation constants.
>
>
> Surface Intercept Routine
>
> The surface intercept routine SURFPT/surfpt_c has been re-implemented
> to reduce loss of precision.
>
>
> DAS Writer Routines
>
> DAS utility routine DASCUD has been fixed to ensure that DAS file
> structure is correct when files are closed without data segregation.
> Previously it was possible for unsegregated files to have an invalid
> final forward directory pointer. Note: this problem could not occur in
> E-kernels created by SPICE utility programs or using the SPICE EK API
> routines.
>
>
> CSPICE Cell Implementation
>
> The CELLINIT macro has been updated so that it doesn't modify data
> added to character cells prior to cell initialization. This enables
> population of uninitialized character cells via macro calls.
>
>
> Body Name to Associated Frame Conversion Routine
>
> The routine CNMFRM retrieving the reference frame name for a specified
> body name has been fixed so a TK frame specified by name and
> designated as an object's preferred frame via kernel pool assignments
> is found, and so that the correct name of this frame is returned.
>
>
> CHRONOS
>
> CHRONOS has been updated to make sure that the iterative search for
> the nearest local midnight converges in all cases. It has also been
> updated to use the maximum system allowed file name length on VAX and
> DEC Alpha environments.
