## 4.7.4 - TBD
-* [Bug Fix] Attempts to set chunking on scalar vars will now return NC_EINVAL. Scalar vars cannot be chunked. Previously the library ignored these attempts and scalar vars were always stored as contiguous. See [https://github.com/Unidata/netcdf-c/issues/1644].
+* [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].
* [Enhancement] Now allow parallel I/O with filters, for HDF5-1.10.3 and later. See [https://github.com/Unidata/netcdf-c/issues/1473].
