32 
33 ### Requirements
34 
35 * netCDF-C: 4.6.0 or greater
36 
37 ### Changes
38 
39 * Moved netCDF classic F90 API tests to new subdirectory nf03_test.
40 * Moved netCDF-4 F77 API tests to new subdirectory nf_test4.
41 * Moved netCDF-4 F90 API tests to new subdirectory nf03_test4.
42 * Fixed bug which caused parallel I/O tests to not be run. See [#155](https://github.com/Unidata/netcdf-fortran/issues/155) and [#157](https://github.com/Unidata/netcdf-fortran/issues/157).
43 * Fixed bug in the setting of file cache preemption for netCDF-4 files. See [#146](https://github.com/Unidata/netcdf-fortran/issues/146).
44 * Removed many near-duplicate tests files, now they are created at build time with sed. See [#165](https://github.com/Unidata/netcdf-fortran/issues/165).
45 * Removed no longer needed configure options --enable-dll (see [#161](https://github.com/Unidata/netcdf-fortran/issues/161)), `--enable-extra-tests` (see [#114](https://github.com/Unidata/netcdf-fortran/issues/114)), `--enable-extra-example-tests` (see [#126](https://github.com/Unidata/netcdf-fortran/issues/126)), and `--enable-valgrind` (see [#118](https://github.com/Unidata/netcdf-fortran/issues/118)).
46 * Moved handling of F77 man page to the docs directory. See [#141](https://github.com/Unidata/netcdf-fortran/issues/141).
47 
48 ## 4.4.5 - Release Jan 9, 2019
49 
50 ### Requirements
51 
52 * netCDF-C: 4.6.0 or greater
53 
54 ### Changes
55 
56 * Removed legacy cfortran.h based build, which allowed F77-only compilers to build the F77 API (only). Since all compilers now support F2003, we can use F2003 features to build the F77 API. Full backwards-compatibility with all existing F77 API code is assured. See [#85](https://github.com/Unidata/netcdf-fortran/issues/85) for more information.
57 * Added an option in cmake builds, `BUILD_EXAMPLES`, `TRUE` by default. When disabled, the examples will not be built. See [#93](https://github.com/Unidata/netcdf-fortran/issues/92) for more information.
58 * Misc. Bugfixes to bring netCDF-Fortran in line with the features in netCDF-C.
59 * Updated CMakeLists.txt to check for C types that match Fortran ones. See [GitHub #67](https://github.com/Unidata/netcdf-fortran/pull/67) for more information.
60 
61 ## 4.4.4 Released May 13, 2016
62 
63 * Corrected an issue where cmake-based builds specifying `USE_LOGGING` were not seeing expected behavior. The issue was reported, and subsequently fixed, by Neil Carlson at Los Alamos Nat'l Laboratory. See [Github Pull Request #44](https://github.com/Unidata/netcdf-fortran/pull/44) for more information.
64 * Integrated improvements provided by Richard Weed. For a *complete* list of modifications, see the file `docs/netcdf_fortran_4.4.2dev_notes_RW.pdf`. **It is highly detailed and worth reading!**
65 
66  The highlights of the improvements are as follows:
67 
68  * Explicit dependencies on `NC_MAX_DIM` constant for arrays has been removed and replaced with dynamically-allocated arrays.
69  * Support for `nc_open_mem()` in the C library, allowing for the creation of "in memory" files.
70  * General clean up.
71 
72 ## 4.4.3 Released 2016-01-20
73 
74 * Corrected a bug which would return a false-positive in `nf_test` when using netCDF-C `4.4.0`.
75 
76 * Updated the `cfortran.doc` license document for the `cfortran.h` library. The most recent version was pulled from http://cfortran.sourceforge.net. The previous version did not reflect that the author had released cfortran under the LGPL. See [Github Issue 27](https://github.com/Unidata/netcdf-fortran/issues/27) for more information.
77 
78 ## 4.4.2 Released 2015-02-02
79 
80 * Added infrastructure to support the new `netcdf-c` option, `ENABLE_REMOTE_FORTRAN_BOOTSTRAP`.
81 
82 * Incorporated changes submitted by Nico Schlomer which extends the cmake compatibility between `netcdf-c` and `netcdf-fortran`.
83 
84 * Incorporated a patch submitted by Thomas Jahns which fixed `FC` being unconditionally overwritten by `F77` when `Fortran 90` was disabled.
85 
86 ## 4.4.1 Released 2014-09-09
87 
88 * No significant changes from RC1.
89 
90 ### 4.4.1-RC1 Released 2014-08-05
91 
92 * Added a new variable for cmake-based builds, `NC_EXTRA_DEPS`. Use this to specify additional dependencies when linking against a static `netcdf-c` library, e.g.
93 
94 ```.fortran
95 netcdf-fortran/build$ cmake .. -DNC_EXTRA_DEPS="-lhdf5 -lhdf5_hl -lcurl"
96 ```
97 
98 * Fixed to build correctly with netCDF-3-only C library, for example C library configured with --disable-netcdf-4 (R. Weed).
99 
100 ## 4.4 Released 2014-07-08
101 
102 * For 32-bit platforms fixed integer fill parameters, initialized potentially
103  unitialized variables, and provided some missing defaults (R. Weed).
104 
105 * Fixed CMake builds on 32-bit platforms.
106 
107 * Added new `inq_path` and `rename_grps` functions analogous to
108  corresponding C functions. Added associated tests (R. Weed).
109 
110 * Added support for NF\_MPIIO, `NF_MPIPOSIX`, `NF_PNETCDF` flags and
111  `NF_FILL_UINT`. (R. Weed)
112 
113 * Fixed potential bug in attribute functions for integer values when
114  Fortran `INTEGER*1` or `INTEGER*2` types are the same size as C
115  long (R. Weed).
116 
117 * Added test for compiler support of Fortran 2008 `ISO_FORTRAN_ENV`
118  additions and TS29113 standard extension.
119 
120 * Fixed `C_PTR_DIFF_T` issue reported by Orion Poplowski (R. Weed).
121 
122 ### 4.4-rc1 Released 2013-10-06
123 
124 * Added doxygen-generated documentation, using the `--enable-doxygen` and `-DENABLE_DOXYGEN` flags for autotools and cmake-based builds, respectively.
125 
126 * Added missing error codes for DAP and some netCDF-4 errors
127 
128 * Fixed some documentation for F77 API, added make rule for creating netcdf-f77 HTML files.
129 
130 ### 4.4-beta5 Released 2013-08-27
131 
132 * Added configuration files to github distribution.
133 
134 ### 4.4-beta4
135 
136 * Moved to GitHub from Subversion, the location of the new GitHub repository is at: http://github.com/Unidata/netCDF-Fortran
137 
138 * Parallel-build portability fixes, particularly for
139  OpenMPI and gcc/gfortran-4.8.x on the Mac. Also added
140  test from Reto Stöckli for NCF-250 bug, demonstrating
141  it was fixed in previous commit.
142 
143 * Add support for NF\_MPIIO, NF\_MPIPOSIX, NF\_PNETCDF, and
144  NF\_FILL\_UINT in the data files.
145 
146 * Add support for nf\_inq\_path.
147 
148 * Add a pre-processor macro that can be used to bypass
149  the home-brew C_PTRDIFF_T definition and use the
150  standard one for compilers that support it.
151 
152 * Fix a potential bug in nf\_attio to call the \_long
153  version of some puts/gets instead of the \_int
154  version. These were inside INT1\_IS\_C\_LONG and
155  INT2\_IS\_C\_LONG ifdef blocks so they would have only
156  showed up when those macros were true.
157 
158 ### 4.4-beta3 Released 2012-12-07
159 
160 * Fixed bug that "make -j check" fails, but "make check" works fine.
161 
162 * Fixed build problems resulting from syncing with separate C distribution.
163 
164 * Synchronize with all changes made to version 4.2 since ts release.
165 
166 ### 4.4-beta2 Released 2012-06-29
167 
168 * Made handling of --disable-f03 more transparent.
169 
170 * Fixed adding flags for parallel I/O for MPI from David Warren.
171 
172 * Removed all the old C code that's not needed for this separate distribution.
173 
174 * Inadvertently broke the build until syncing with C distribution in later beta release.
175 
176 ### 4.4-beta1 Released 2012-03-02
177 
178 * `Fortran 2003 Support`
179 
180  Version 4.4 is the first release to support fortran 2003 and to use the ISO C Bindings available in fortran 2003 to replace the older C code wrappers.
181 
182  Congratulations and thanks to Richard Weed at Mississippi State University, who is the author of new code.
183 
184  See the file `README_F03_MODS` for a more complete description of the changes. Many changes to the build structure have been made at the same time as the new 2003 code has been inserted.
185 
186  As part of the fortran 2003 refactor, the directory structure has been significantly modified. All the previous F90 C wrapper code has been moved to the "libsrc" directory.
187 
188  All of the fortran code has been moved to the "fortran" directory. The directories names F77 and F90 have been removed. The most important consequence of this refactor is that pure Fortran77 compilers are no longer supported. It is assumed that the compiler supports at least Fortran 90 and also Fortran 77. If it also supports the ISO C Bindings, then the new 2003 code is used instead of the older C wrappers.
