netCDF-4.4.1-rc1

on GitHub

This is the first release candidate for netCDF 4.4.1. It contains many improvements and bug fixes, and addresses one very important issue. This is the first release which will write backwards-compatible netCDF4 files properly when linked against HDF5 1.10.0. See #250 for full details.

See the file RELEASE_NOTES.md for full release notes. Here is a summary of changes made so far:

Changes from 4.4.0 to 4.4.1-rc1

• [Bug Fix][Enhancement] Fixed an issue with netCDF4 files generated using version 1.10.0 of the HDF5 library. The 1.10 release potentially changed the underlying file format, introducing a backwards compatibility issue with the files generated. HDF5 provided an API for retaining the 1.8.x file format, which is now on by default. See GitHub Issue #250 for more information.
• [Bug Fix] Corrected an issue with autotools-based builds performed out-of-source-tree. See GitHub Issue #242 for more information.
• [Enhancement] Modified nc_inq_type() so that it would work more broadly without requiring a valid ncid. See GitHub Issue #240 for more information.
• [Enhancement] Accepted a patch code which added a hashmap lookup for rapid var and dim retrieval in nc3 files, contributed by Greg Sjaardema. See GitHub Pull Request #238 for more information.
• [Bug Fix] Accepted a contributed pull request which corrected an issue with how the cmake-generated nc-config file determined the location of installed files. See GitHub Pull Request #235 for more information.
• [Enhancement] Added an advanced option for CMake-based builds, ENABLE_SHARED_LIBRARY_VERSION. This option is ON by default, but if turned off, only libnetcdf.dylib will be generated, instead of files containing the SOVERSION in the file name. This is a requested feature most people might not care about. See GitHub #228 for more information.
• [Bug Fix] Corrected an issue with duplicated error codes defined in multiple header files. See GitHub #213 for more information.
• [Bug Fix] Addressed an issue specific to Visual Studio 2015 on Windows. On very large files, some calls to the fstat class of functions would fail for no apparent reason. This behavior was not observed under Visual Studio 2013. This has now been mitigated. See GitHub #188 for more information.
• [Enhancement] Updated nc-config to report whether logging is enabled in netcdf. Additionally, if f03 is available in an installed netcdf-fortran library, it will now be reported as well.
• [Bug Fix] Addressed an issue where netcdf_mem.h was not being installed by cmake. See GitHub #227 for more information.
• [Bug Fix] Addressed an issue where ncdump would crash when trying to read a netcdf file containing an empty ragged VLEN variable in an unlimited dimension. See GitHub #221 for more information.
