    Release Notes: This release has a properly defined and documented C-API named c_fimex.h. With that, the most important functionality of fimex is now accessible directly from C rather than the underlying C++. This includes reading data from various data formats as well as writing C filters to the fimex filter pipeline.

      Release Notes: The translation engine for projection paramters has been rewritten in 0.16, and this introduced translation errors in situations where several parameters were needed to be given. This problem has been solved in this bugfix release. Some netcdf-files mark not only observed variables with the "grid-mapping" attribute, but also auxiliary variables. Fimex will now try to double-check the reprojection of variables by excluding variables not containing the "coordinates" flag, which should effectively exclude auxiliary variables.

        Release Notes: Fimex is now able to read grib-files of the WMO grib edition 1 and 2. For fast and repeated reading of grib-files, a index of all grib-messages can be generated automatically or manually by using the new indexGribs program. In addition, the support for ellipsoids has been improved. This release started to simplify the API and build-system to make it easier to use fimex as a library.

          Release Notes: Fimex comes now bundled with another library for reading felt files. This increases performance and simplifies the build process, since linking to Fortran libraries is no longer required. This version is able to link against the udunits2 library instead of only the udunits library. The fimex library can now also been built as a dynamic library. In addition, the Lambert Conform Conic projection is now fully supported.

            Release Notes: This release concentrates on stability in production. It solves some issues while translating the felt parameters of a rotated latitude-longitude projection to proj and FGDC (CF-1.0). It also solves possible segmentation faults with older versions of libxml which return a null pointer rather than a 0-sized list when an xpath cannot be found. In addition, some compiler warnings have been found and resolved.

              Release Notes: This release adds new features most useful for interpolation and extraction of measurement data, in particular satellite imagery. Several new forward interpolation methods have been added to change the projection of the original image. This allows high-resolution data to transit to a lower resolution by selecting the sum, average, maximum, minimum, or median of all corresponding data points. In addition, data which doesn't meet configurable quality constraints (i.e., status-flags from the measurement instrument) can be removed with the new CDMQualityExtractor filter.

                Release Notes: This release concentrates on support for the NetCDF Markup Language (NcML). It allows users to read data through NcML as well as manipulate and write NetCDF files configured with NcML. By request from some users, fimex has been backported to support the netcdf-library starting from version 3.5. In addition, the tests will no longer fail if a boost version less than 1.34 is given, although not all tests will be able to run.

                  Release Notes: Fimex is able to automatically detect the largest bounding box in the output projection pane, and can automatically adjust the output axes to that bounding box. In addition, the netcdf-writer configuration allows one to remove attributes and variables from the output file. 0.12 introduced a bug that caused several interpolations to map to completely artificial cells. The affected interpolations use projections different than latitude-longitude using the methods nearest-neighbor, bilinear, or bicubic This bug has been removed.

                    Release Notes: Fimex is now able to reproject data which is indexed only by coordinates, such as data coming from GHRSST satellite files. To sustain the performance of these interpolations, either kdtree or brute-force search can be done. The brute force search makes use of multiple processors by using OpenMP. In addition, the build process has been simplified and smaller bugs have been fixed.

                      Release Notes: Fimex can now be linked against the netcdf-4 library. It is now a configuration option to use the new hdf5-based netcdf4 file format. The zlib compression level of these files can also be configured, either on by total or per dataset. With the netcdf-4 library, fimex can be used for easy conversion between netcdf-3 files and compressed netcdf-4 files. The spatial interpolations routines have also been enhanced to include bicubic interpolation besides bilinear and nearest neighbor interpolation.
