 ## 4.7.4 - TBD
 
+* [Bug Fix] Correct behavior for the command line utilities when directly accessing a directory using utf8 characters. See [Github #1669](https://github.com/Unidata/netcdf-c/issues/1669), [Github #1668](https://github.com/Unidata/netcdf-c/issues/1668) and [Github #1666](https://github.com/Unidata/netcdf-c/issues/1666) for more information.
 * [Bug Fix] Attempts to set filters or chunked storage on scalar vars will now return NC_EINVAL. Scalar vars cannot be chunked, and only chunked vars can have filters. Previously the library ignored these attempts, and always storing scalars as contiguous storage. See [https://github.com/Unidata/netcdf-c/issues/1644].
 * [Enhancement] Support has been added for multiple filters per variable.  See [https://github.com/Unidata/netcdf-c/issues/1584].
 * [Enhancement] Now nc_inq_var_szip retuns 0 for parameter values if szip is not in use for var. See [https://github.com/Unidata/netcdf-c/issues/1618].
