+[PnetCDF](https://parallel-netcdf.github.io) Version 1.12.3 Release Notes (January 21, 2021)
+------------------------------------------------------------------------------
+
+* New optimization
+  + Improve the performance when nonblocking requests contain more than one
+    record.
+    See [a00f5d2](https://github.com/Parallel-NetCDF/PnetCDF/commit/a00f5d2).
+
+* Update configure options
+  + Retire configure options `--enable-netcdf4` and `--enable-adios`, as there
+    are already options `--with-netcdf4` and `--with-adios`. According to the
+    autoconf manual, `--enable-feature` is for internal packages and
+    `--with-feature` is for external.  Adding `--with-feature` is equivalent to
+    enabling the feature.
+
+* Updated utility program
+  + Replace the definition of "difference ratio" used in utility programs
+    `cdfdiff` and `ncmpidiff` with formula
+    ```
+    |x - y| / max(|x|, |y|)
+    ```
+    where |x| means the absolute value of x.
+    See [issue #78](https://github.com/Parallel-NetCDF/PnetCDF/issues/78) and
+    [9b165ceb](https://github.com/Parallel-NetCDF/PnetCDF/commit/9b165ceb).
+  + Utility programs `cdfdiff` and `ncmpidiff` now report only the first
+    variable element that are different or fail to meet the tolerances. Their
+    values and differences are now printed on the standard output.
+    See [75d20e6](https://github.com/Parallel-NetCDF/PnetCDF/commit/75d20e6)
+    and [58d2d17](https://github.com/Parallel-NetCDF/PnetCDF/commit/58d2d17).
+  + Use the same user-provided tolerant difference and tolerant difference
+    ratio (through command-line option '-t') to check all variables.
+    See [issue #78](https://github.com/Parallel-NetCDF/PnetCDF/issues/78) and
+    [75d20e6](https://github.com/Parallel-NetCDF/PnetCDF/commit/75d20e6).
+
+* Other updates:
+  + IBM XLF compiler on Summit at OLCF requires compile flag "-qfixed" when
+    compiling Fortran programs written in fixed form. Thus, the fixed form flag
+    detected at configure time has been added to `AM_FFLAGS` when compiling
+    fixed form programs. Similarly, the free form flag has been added to
+    `AM_FCFLAGS` when compiling free form programs. This issue affects only the
+    test and example Fortran programs. The PnetCDF library is intact.
+    See [PR #73](https://github.com/Parallel-NetCDF/PnetCDF/pull/73)
+  + Add all PnetCDF I/O hints to the inquired MPI info object returned by API
+    `ncmpi_inq_file_info()`.
+    See [f0e65cf](https://github.com/Parallel-NetCDF/PnetCDF/commit/f0e65cf).
+
+* Bug fixes
+  + Fix a bug in utility program `ncvalidator` for the case when there is no
+    record written, but both fixed-size and record variables are defined.
+    See [b34bfcd](https://github.com/Parallel-NetCDF/PnetCDF/commit/b34bfcd).
+  + Fix configure bug of setting environment variable `SEQ_CC` to the
+    sequential `CC` extracted from `MPICC`. Also add configure help message for
+    environment variable `SEQ_CC`. Thanks to Carl Ponder for reporting.
+    See [4978f6d](https://github.com/Parallel-NetCDF/PnetCDF/commit/4978f6d).
+  + Fix a bug when C function `truncate` is not available. Argument `fh` of
+    `MPI_File_close` is a pointer.
+    See [3e331a6](https://github.com/Parallel-NetCDF/PnetCDF/commit/3e331a6).
+  + When using an MPI compiler whose Fortran feature was disabled, the MPI
+    Fortran constants and datatypes may not be defined in the header file
+    `mpi.h`. This is the case for Open MPI (tested with 4.0.2). PnetCDF used
+    some Fortran datatypes without checking whether they are defined, which can
+    fail when running 'make'. A fix has been added to check whether the Fortran
+    feature is disabled and wraps around the Fortran datatypes with C directive
+    'ifdef ENABLE_FORTRAN'. Thanks Bert Wesarg for reporting this bug.
+    See [issue #68](https://github.com/Parallel-NetCDF/PnetCDF/issues/68) and
+    [PR #69](https://github.com/Parallel-NetCDF/PnetCDF/pull/69).
+
+* Issues with NetCDF library
+  + Test program [test/nc4/tst_rec_vars.c](test/nc4/tst_rec_vars.c) fails to
+    run when using NetCDF 4.8.0 and 4.8.1. Thanks Bruno Pagani for reporting.
+    See [issue #72](https://github.com/Parallel-NetCDF/PnetCDF/issues/72).
+
+* Clarifications
+  + Nonblocking APIs have yet to support subfiling feature.
