Breaking changes

• chunksize is now a tuple of integers (was a vector of integers). On input (of defVar and chunking), a vector of integers is still accepted for compatibility.
• idimensions key word argument is dropped from write. Use SubDatasets instead to write a subset of a netcdf file.
• The container type of dimensions and attributes (Dimensions and Attributes) are now subtypes of AbstractDict{Union{Symbol, AbstractString},Any}.
  • Certain functions like map are explicitly disallowed for AbstractDict. Calls like map(fun,ds.dim) where fun is a function and ds a netCDF datasets need to be replaced by map(fun,collect(ds.dim)).
  • The type of Dict(ds.dim) is now Dict{Union{Symbol, AbstractString},Any} while it was a Dict{Union{Symbol, String},Any} before.
• NCDatasets.CFVariable was moved to CommonDataModel.CFVariable. NCDatasets.NCDataset(var::NCDatasets.CFVariable) is no longer supported, use NCDatasets.dataset(var::CommonDataModel.CFVariable) instead.

Note

• If you notice other breaking changes please file an issue in order to either update the release notes or to fix an unintended change.
• Many functions and types not specific to NetCDF files (multi-files, views, and load by value) have been moved to CommonDataModel.jl

NCDatasets uses now the DiskArray package which required some API changes.
In general, the array API of NCDatasets is now more similar to base Julia in particular:

• ncvar[range_indices] = scalar should now be ncvar[range_indices] .= scalar
• ncvar2D[:] flattens the data in the 2D NetCDF variable ncvar2D. To read the full array one need to use ncvar2D[:,:] or Array(ncvar2D) (similarly for 3D, 4D... arrays).
• Accessing an array out of bounds, new returns a DimensionMismatch exception (previously a NCDatasets.NetCDFError exception was returned)
• To grow a NetCDF variable with unlimited dimension, the corresponding index of left-hand side of the assignment cannot be a colon, but should be a range. For example if ncvar is a NetCDF variable where the 2nd dimension is unlimited, ncvar[:,:] = zeros(2,3) should now be replaced by ncvar[:,1:3] = zeros(2,3)
