## 4.8.2 - TBD
-* [Enhancement] Turn on the XArray convention for NCZarr files by default. See [Github #2257](https://github.com/Unidata/netcdf-c/pull/2257).
+* [Enhancement] Turn on the XArray convention for NCZarr files by default. WARNING, this now means that the mode must contain "nczarr" or "zarr" even if "xarray" or "noxarray" is specified. See [Github #2257](https://github.com/Unidata/netcdf-c/pull/2257).
* [Enhancement] Improve filter support. More specifically (1) add nc_inq_filter_avail to check if a filter is available, (2) add the notion of standard filters, (3) cleanup szip support to fix interaction with NCZarr. See [Github #2245](https://github.com/Unidata/netcdf-c/pull/2245).
* [Bug Fix] Require that the type of the variable in nc_def_var_filter is not variable length. See [Github #/2231](https://github.com/Unidata/netcdf-c/pull/2231).
* [File Change] Apply HDF5 v1.8 format compatibility when writing to previous files, as well as when creating new files. The superblock version remains at 2 for newly created files. Full backward read/write compatibility for netCDF-4 is maintained in all cases. See [Github #2176](https://github.com/Unidata/netcdf-c/issues/2176).
