      interface locations from cell midpoints), and outputs the gridfile
      in SCRIP-format for easy use by offline regridders.
    * ncks --rgr skl='y' creates a "skeleton" version of a data file
      with the specified geometry.
    * Generate 2-D regional grids in SCRIP format, and, in conjunction
      with a mapfile, regrid to/from regional bounding boxes.
    * Use --xtn_var or --extensive to specify extensive variables.
    * Fix: ncks fixes two newly uncovered regridder bugs that were exposed by
      multi-level fields that contain missing values and underwent
      non-conservative (e.g., bilinear) regridding.
    * Fix: ncap2 now evaluates logical expressions with a method that does
      not convert the type of the arguments to lesser precision.
    * Fix: ncecat version 4.4.9 introduced a problem that could cause it
      to fail when using --gag mode on a single file.
    * Fix: ncatted version 4.5.1 introduced a bug that dumps core when
      attribute deletion is requested without a specific attribute name,
      i.e., whenever all attributes are to be deleted.
  - Update to 4.5.2:
    * All operators can now add user-specified global attributes to
      output files using the --glb switch.
    * Grid generation: ncks generates SCRIP-format gridfiles for
      select grid types, in cluding uniform/equi-angular, cap/FV, and
      Gaussian. Options pertinent to the grid geometry and metadata are
      passed to NCO via key-value pairs prefixed by "--rgr".
    * Regrid regional datasets with ESMF, SCRIP, and TempestRemap
      mapfiles. Please give it a try and send us feedback!
    * Multi-file operators support a new extension to the -n option
      that understands calendar month counting.
    * Fix: The ncra --wgt option, introduced in 4.4.9, works fine except,
      it turns out, for variables with missing values. The normalization
      for these values was incorrect and produced errors whose size was
      roughly inversely proportional to the size of the weights.
  - Update to 4.5.1:
    * Regrid global datasets with TempestRemap mapfiles (in addition to
      ESMF and SCRIP, which were already supported).
    * ncatted now supports regular expressions in both the variable name
      AND the attribute name (simultaneously, too). Previously, ncatted
      accepted regular expressions only in the variable name.
    * Add mibs/mabs/mebs methods and operators to ncap2. These are the
      absolute-value analogues of min/max/mean, so that, e.g., mibs()
      returns the minimum absolute-value of the operand.
    * Prevent operators from repeating existing cell_methods attribute.
      Previously NCO would append new operations, e.g., "time: mean" to
      the existing cell_methods attribute, if any.
    * Fix formatting of history_of_appended_files attribute when appended
      file had no history attribute.
    * Fix: Round-up to one rather than round-down to zero in chunking maps lfp
      and rew. This fixes a bug that only appears on datasets with
      certain shapes.
    * Fix bug using min/max on coordinate variables in ncap2
    * Fix: Initialize memory that appeared to cause zeros to be written
      by regridder compiled by clang on MacOSX.
  - Update to 4.5.0:
    * Regrid global datasets with ESMF or SCRIP remap files.
    * ncdismember is a one-stop shop for flattening and CF-checking.
    * NCO introduces a convention to retain the history-attribute
      contents of all files that were appended to a file.
    * When copying the variables date_written or time_written to the
      output file, NCO now updates their contents the GMT time reported
      by the system-supplied gmtime().
    * Fix ncatted so it preserves global attributes (including history)
      from the output file when in append (-A) mode.
* Sat Nov 26 2016

      One non-fatal failure on icc Linux (yellowstone) ncecat#9

    * Initialize input chunksize defaults correctly for ncwa, ncecat, ncpdq
    * Replace strncpy() in sng_trm_trl_zro() with explicit loop to prevent valgrind complaining about,
      and Mac OS X crashing on, overlapping source and destination buffers

    * Add regression for auxiliary coordinates
    * First regression-free version in three weeks
    * Now that nco_cnk_sz_set_trv() always called, allow it to work when ncecat creates new record dimension
    * Fix long-time bug where nco_cpy_var_dfn_trv() incorrectly sets dmn_cmn[].is_rec_var for record dimensions affected by
    - -fix_rec_dmn or --mk_rec_dmn invocation (always set incorrectly except on first variable affected)
    * Adjust regression tests to work with --cnk_min. Document --cnk_min.
    * ncap_cst_mk() in checks that record dim is the first dim in list ONLY if nc3 file
      and nc4 file. This also allows users to define vars with multiple record dims.
    * Add hidden feature to defdim(): when dim_sz < 0 then dim is defined as unlimited
    * Replace NETCDF4_ROOT by NETCDF_ROOT in configure
    * Add --cnk_min to specify minimum size (default 8kB) in bytes of variable to chunk
    * Change --enable-dap-netcdf to --enable-dap
    * Add cnk.cdl to test chunking algorithms
    * Add cnk_map=nco to assign to current NCO-recommended map
    * Always call chunking
    * Stubs for cnk_map = nc4 for default netCDF4 chunking (same as unchunking for now?)

    * Add numerous regression tests to evaluate nc_rename_var/dim() behavior.
    * Avoid nc_rename_var/dim() bug in netCDF4 files by avoiding nc_redef()/nc_enddef(). No dice.
    * Improve hdr_pad, ncrename documentation
    * Add NCO_VERSION for consistency with NC_VERSION
    * Document newly discovered ncrename problems due to netCDF4 bugs
    * Check more error return codes in ncrename.c. Verifies NCO does not ignore any netCDF errors.
    * Add regression checks for valid values in renamed coordinates in netCDF4 files
    * Change to real Python convention where -1 is last element, e.g., -2 is penultimate element, -N is first element
* Sat Nov 01 2014
  - Updated to 4.4.6
    * Add negative zero syntax to select last element of hyperslab.
    * Avoid void arithmetic in USE_NC4_SRD_WORKAROUND.
    * Change important nco_calloc() to nco_malloc() for speed.
    * Fix ncwa handling of packed variables for minimization/maximization.
    * Implement strncasecmp() for Windows and MSVC compilers.
    * Fix count bug in USE_NC4_SRD_WORKAROUND.
    * Implement USE_NC4_SRD_WORKAROUND by default in all applicable cases,
      i.e.,  for singly strided hyperslab access to netCDCF4 files.
    * Implement workaround to nc_get_vars() slowdown for netCDF4 in netCDF
      library Workaround avoids nc_get_vars() and instead loops through calls
      to nc_get_vara() Workaround implemented in nco_msa_get_var_trv() and
      activated, for now, by -D 6.
    * Finish ncrename rewrite. All capabilities work. No regressions.
      Some debugging, syntax, and documentation remains to be done.
    * Use netcdf_meta.h in nco.h to enable chunking/deflation calls for HDF4.
    * ncrename now builds and works again for all but attributes.
    * Print extended file format as _SOURCE_FORMAT with ncks --hdn.
    * Remove nco_dmn_usr_sng() and nco_obj_usr_sng() due to flawed algorithms.
    * Finish ncrename re-write for variables, groups, and dimensions.
      NCO versions 4.3.3-4.4.5 broke "." support and did not fully support
      groups.  Those versions renamed first and ignored subsequent instances
      of old_nm.  Now ncrename fails as intended when required objects are not
      present.  Attributes are more complex and are still broken.
    * Support netCDF 4.3.3 netcdf_meta.h in nco_netcdf.h so NC_HAVE_RENAME_GRP
      is found.
    * Add regression tests to make ncrename die when required entities not
    * Fix bug with ncra --dbl on packed variables with missing values.
    * Add debugging statements to track netCDF4 stride slowdown.
    * Note locations which assume record dimension is in first position.

    * Add regression test to demonstrate bug with ncra --dbl on
      packed float variables with missing values.
    * Implement missing getopt() line for file_format switch.
    * ./configure now checks for daperror() instead of nc__opendap().
    * Add NC_EIO error clarifications.
    * Create -V = --var_val = -Q --no_nm_prn for ncks to print only variable
    * Document -Q and -V and switch --quiet to -Q (not -q) and synonomize -q
      with --quench.
    * Clarify WARNING when record dimension size changes.
    * ncap2 command-line and script arguments can now both be specified AND
      executed.  Command-line args are executed before script:
      ncap2 -v -s "lon=longitude" -S
