-The netCDF Operators NCO version 4.7.6 have hatched.
+The netCDF Operators NCO version 4.7.7 have hatched.
 
 http://nco.sf.net (Homepage, Mailing lists, Help)
 http://github.com/nco (Source Code, Issues, Releases, Developers)
 
-What's new?
-Version 4.7.6 is primarily a feature release for ncremap.
-There are two new processing modes, one for regridding regional data,
-and one for generating all mapfile permutations with all interpolation 
-algorithms. There is also improved support for auxiliary coordinates
-that lack coordinaes/standard_name conventions, improved ncap2
-command-line script handling in Windows, and less intrusive HPSS file
-system support. 
+What's new? Version 4.7.7 has modest new features everywhere:
+Improved forward and backward compatibility with newer and older
+versions of ESMF_RegridWeightGen; Generation and inferral of grids
+running north->south (à la ECMWF); exact symmetry for Gaussian grid
+interfaces; an ncpdq compression map that converts doubles to floats;
+production of "skeleton files" for new grids; equivalent treatment of
+MPAS and CESM grid variables in arithmetic; and reversion of the
+filename whitelist security. 
 
 Work on NCO 5.0.0 has commenced "under the hood". The key leap in that 
 release will be support for netCDF4 user-defined types. Printing of
 netCDF4 user-defined types ENUM and VLEN is ready now (though
 unsupported) with the --udt flag. 5.0.0 will contain the finished
-version of that, and progress on weight generation by ncremap. 
+version of that, and progress on native weight generation by ncremap.
 
 Enjoy,
 Charlie
 
 NEW FEATURES (full details always in ChangeLog):
 
-A. NCO versions 4.6.6+ (April, 2017) has looked for files on an HPSS
-   filesystem when it could not find them elsewhere. This produces
-   messages considered intrusive by many users, who do not have HPSS.
-   Now users must opt-in to HPSS searches by adding the --hpss flag:
-   ncks -l . --hpss /home/zender/nco/in.nc
-   http://nco.sf.net#hpss
-
-A. ncremap now regrids regional output produced by CESM CAM-SE and
-   E3SM EAM models. Models output these RRG (for "regional
-   regridding" format) files if requested by the finclNlonlat
-   namelist parameter. RRG files from FV-dycore simulations were
-   already regriddable, and now SE-dycore RRG files are too:
-   ncremap --dat_glb=dat_glb.nc --grd_glb=grd_glb.nc -g grd_rgn.nc dat_rgn.nc dat_rgr.nc
-   Documentation is currently available to E3SM users at
+A. ncpdq has a new packing map: dbl_flt
+   The map converts to double-precision to single-precision,
+   so it is technically a precision change, not packing.
+   It is in ncpdq because it reduces space by ~50%, like packing.  
+   Like packing the precision loss is irreversible.
+   Unlike packing, no attributes are created, modified, or deleted.
+   ncpdq -M dbl_flt in.nc out.nc
+   http://nco.sf.net/nco.html#dbl_flt
+   http://nco.sf.net/nco.html#ncpdq
+
+B. Filename sanitization via character whitelists, first introduced in
+   NCO 4.7.3 to increase security against malicious filenames, has
+   been turned-off, possibly permanently. Points passionately raised
+   by a user led us to turn-off this feature until lack of it is shown
+   to lead to a real-world exploit.
+   https://github.com/nco/nco/issues/104
+   http://nco.sf.net/nco.html#wht_lst
+
+C. The CCM/CAM/EAM family of atmospheric models does not output a
+   "bounds" variable or attribute corresponding to its "lev"
+   coordinate. This prevents NCO from activating some desirable CF
+   machinery. To workaround this, NCO now outputs the ilev coordinate
+   (and hyai, hybi) whenever the lev coordinate is also output.
+   ncks -v T in.nc out.nc
+   http://nco.sf.net/nco.html#bnd   
+   
+D. Equivalent treatment of MPAS and CESM grid variables.
+   NCO does not arithmetically alter grid-related variables.
+   Who wants to subtract latitude coordinates from eachother?
+   Previously it only skipped arithmetic on CESM'ish grid variables.
+   Now NCO has an extensive (pun intended!) list of MPAS and other
+   grid variables that it will not subtract. For the most part,
+   ncremap will not regrid these variables either.
+   http://nco.sf.net/nco.html#cnv_CCSM
+   http://nco.sf.net/nco.html#cnv_MPAS
+   http://nco.sf.net/nco.html#ncremap
+
+E. I greatly expanded the field manual to regridding with ncremap.
+   The documentation is currently available to E3SM users at
    https://acme-climate.atlassian.net/wiki/spaces/SIM/pages/754286611/Regridding+E3SM+Data+with+ncremap
    and to others via email request (it will be in Users Guide soon).
 
-A. ncremap includes an MWF-mode (for "Make All Weight Files") that
-   generates and names, with one command and in a self-consistent
-   manner, all combinations of E3SM global atmosphere<->ocean maps
-   with both ERWG and Tempest. MWF-mode automates the laborious and
-   error-prone process of generating numerous map-files with various
-   switches. Its chief use occurs when developing and testing new
-   global grid-pairs for the E3SM atmosphere and ocean components:   
-   ncremap -P mwf -s grd_ocn -g grd_atm --nm_src=ocn_nm --nm_dst=atm_nm --dt_sng=date
-   Documentation is currently available to E3SM users at
-   https://acme-climate.atlassian.net/wiki/spaces/SIM/pages/754286611/Regridding+E3SM+Data+with+ncremap
-   and to others via email request (it will be in Users Guide soon).
-
-A. ncap2 string-handling is now more compatible between Windows and
-   better OSs. Previously, some ncap2 scripts could behave differently
-   due to the Windows definition of the C++ c_str() function.
+F. ncremap adds --ignore_degenerate to default ESMF_RegridWeightGen
+   (ERWG) options when ERWG version >= 7.0. This is done to preserve
+   backwards compatibility since ERWG 7.1.0r and later require
+   --ignore_degenerate to successfully regrid some datasets (e.g.,
+   CICE) that previous ERWG versions handle fine.  
+   ncremap -m map.nc in.nc out.nc
+   http://nco.sf.net/nco.html#wgt_opt
+
+G. Not only do the British drive on the wrong side of the road, they
+   prefer North-to-South (n2s) grids over South-to-North (s2n) grids. 
+   NCO now implements a latitude direction keyword lat_drc.
+   Grid generation implements n2s ordering via --rgr lat_drc=n2s.
+   Grid diagnosis now recognizes n2s ordering for all rectangular grids.
+   http://nco.sf.net/nco.html#lat_drc
+
+H. ncremap now generates exactly symmetric interface latitudes for
+   Gaussian grids. To our knowledge only NCO generates accurate
+   Gaussian interfaces (via a Newton-Raphson iteration of boundaries 
+   to enclose the area indicated by the Gaussian weight). However,
+   previously the interface latitudes could accumulate rounding errors
+   during Newton-Raphson iteration differ between the hemispheres by
+   ~1.0e-14. Now symmetry properties are used to ensure exact symmetry. 
+   http://nco.sf.net/nco.html#gss
+
+I. ncremap now produces a "skeleton file" of grids it generates
+   when requested with --skl_fl.
+   ncremap -G latlon=2560,5136#lat_typ=gss#lon_typ=grn_ctr#lat_drc=n2s -g grd_ecmwf.nc --skl=skl_ecmwf.nc
+   http://nco.sf.net/nco.html#skl_fl
+   http://nco.sf.net/nco.html#skeleton
 
 BUG FIXES:
 
-A. NCO completes when chunking into non-netCDF4 files (of course it
-   ignores the chunking request). Previous NCO tried to complete but
-   dumped-core. 
+A. ncks -r could incorrectly report that CDF5 was enabled.
+   This occurred when linked to netCDF 4.5.x-4.6.1.
+   This has been fixed.
 
-A. NCO now only prints one WARNING about user-specified chunk size for  
-   record dimension being too big.
+B. ncremap previously broke on weight files that lacked a num_wgts
+   dimension, even if that dimension was unused (orphaned). 
+   Dependence on num_wgts has been eliminated and fixes this.
+   This also enables compressed maps to work correctly.
 
-A. Repeated notice: netCDF 4.6.1 fixes the CDF5 bug described here
-   http://nco.sf.net#bug_cdf5
-   We STRONGLY recommend that CDF5 users upgrade to netCDF 4.6.1.
-   NCO error messages and HINTs have been updated to better describe
-   the best practices to identify and avoid this nasty bug.
+C. Fixed a bug in the convergence test to detect Gaussian grids
