                             RELEASE NOTES FOR HEASOFT 6.26
                                       May 17, 2019
    ********************************************************************************
    
    The HEASoft 6.26 release is driven by several updates to mission-specific
    data analysis software (MAXI, NICER, et al.), but includes many other
    enhancements and fixes, including updates to most legacy software which
    fix run-time memory issues under newer Debian-based Linux OS (i.e. Ubuntu
    18.10 and 19.04).
    
    As before, configuration-related changes throughout the package mean that
    users who already have HEASoft installed will need to completely replace
    their software installation; there is no clean way to simply overlay
    this new release or to update an existing installation.
    
    ********************************************************************************
                                        CFITSIO
    ********************************************************************************
    
    - Added set of drivers for performing ftps file transfers.
    
    - Tile sizes for compression may now be specified for any pair of
      axes, where previously 2D tiles where limited to just X and y.
      
    - Fix to ffgsky and ffgkls functions for case of keyword with long
      string values where the final CONTINUE statement ended with '&'.
      If the final CONTINUE also contained a comment, it was being 
      repeated twice when passed back through the 'comm' argument.
    
    - Fix made to ffedit_columns() for case of multiple col filters
      containing wildcards.  Only the first filter was being searched.
    
    - fits_copy_rows (ffcprw) can now handle 'P'-type variable-length columns.
      
    - Fix made to an obscure case in fits_modify_vector_len, where a 
      wrongly issued EOF error may occur.
    
    - Added internal fffvcl() function.
    
    - Fixed bug in new 0-or-more wildcard pattern matching; one is to handle
      the match like -#COMMENT+ which doesn't have a wildcard, but still needs
      to match 0-or-more; a second is a 'bug' dealing with how CFITSIO scans
      for keywords with and without wildcards and whether the 'current' header
      position is reset or not.
    
    ********************************************************************************
                                        ATTITUDE
    ********************************************************************************
    
    - prefilter: Replaced call to obsolete atRigidity (float) with
      atRigidityD (double), and excised call to initialize_asca_derive_cor
      which was just a wrapper to the obsolete function atRigSet.
    
    - aspect: Initialized local variables

                                        HEASARC
    ********************************************************************************
    
    - nh: Changed the default map to the HI4PI (A&A, 594, A116);
      changed the default parameters size and disio to be optimized to
      the HI4PI map; changed array size and type; added code to trap

                                    HEASP / HEASPTOOLS
    ********************************************************************************
    
    - Changed rmf compression criterion to only include elements with
      values > LO_THRES instead of >= LO_THRES
    
    - Updates to Python module to work for both Python 2 and 3.
    
    - Trapped a potential problem in getValues if maxEindex < minEindex;
      Write EBOUNDS and MATRIX energy columns as D instead of E to avoid
      precision issues with high-resolution optical/UV spectra
    
    - ftsdss2xsp: Fixed check of PLATEID keyword. It is in the primary header,
      not the COADD extension.
    
    - Added wrappers for some old CALTOOLS and HEASARC tasks (see above):
      rbnpha, rbnrmf, gcorpha, gcorrmf, genrsp, rsp2rmf
    
    ********************************************************************************
                                        HEATOOLS
    ********************************************************************************
    
    - ftmerge: (v2.3) Flush output table after each input is processed
    
    - ftsort (v1.8), ftmergesort (v2.0): Improved to handle variable-length
      columns
    
    - ftverify: (v4.19) Added option to test that HIERARCH keywords conform

    ********************************************************************************
                                         TIME
    ********************************************************************************
    
    - Replaced udmget/udmfre with allocate/deallocate in the following tasks:
    
      deadtime, fltime, mgtime
    
    - maketime: (v2.15) Fixed bug in new premax/postmax code - now correctly
      handles gaps; improved premax/postmax logic for corner cases
    
    ********************************************************************************
                                        XRONOS
    ********************************************************************************
    
    - Note that under newer Debian-based systems (e.g. Ubuntu 18.10 and
      newer), many XRONOS tasks currently suffer memory faults.  These
      are expected to be fixed in a later HEASoft release or patch.
    
    - (libxronos) Fixed attempts to address arrays with 0 index as kmax array
      has not been initialized
    
    ********************************************************************************
                                        XSELECT
    ********************************************************************************
    
    - Fix for 'select hk' command: Needed to specify prefr/postfr parameters to
      maketime to avoid an output message that xselect interpreted as a failure.
    
    - Trapped case of region not being set when one is required to make the response.
    
    - When writing out the observation catalog no longer page but write the whole
      thing out in one go.  Since everyone has scrolling terminal windows paging
      is no longer necessary and the change enables running scripts with large
      observation catalogs.

    ********************************************************************************
                                        VELA5B
    ********************************************************************************
    
    - Replaced udmget/udmfre with allocate/deallocate in the following tasks:
    
      fvelalc, fvelgallc, fvelmap
    
    - fvelalc: (fvelalc.par) Added default values to maxflux & maxerr parameters
    
    - fvelgallc: Commented out NAXIS=2 error condition trap as NAXIS comes
      up as 0 incorrectly in some rare instances (unless optimization is
      lowered) and is otherwise unused; other FITS characteristics are correct
    
    ********************************************************************************
                                         XTE
    ********************************************************************************
    
    - Replaced udmget/udmfre with allocate/deallocate in the following tasks:

    ********************************************************************************
                                         MISC.
    ********************************************************************************
    
    - PGPLOT: Made checking for drivers that use 'vector' fonts more generic;
      Prevent text field overflow when writing PostScript files; modified
      degrees-minutes-seconds labeling code to be more visually consistent;
      old symbols were effectively superscripted twice, which leads to small and
      high symbols; now they are at same level and size as 'd' 'h' 's' symbols
    
    - Updated handling of shared libraries on Linux, i.e. to use rpath and to
      resolve symbols (where possible) at library build time.  Reworked linker
      flags on Macs: synchronized shared library linker flags to all use
      "-undefined dynamic_lookup", adding "-flat_namespace" when using XCode
      clang[++] or (just) for Python libraries when _not_ using XCode clang[++].
      This approach fixes problems loading Python libraries when built with a
      complete (third-party) GCC suite.
