 # v0.20
 
+- Throw `KeyError` if `getBlobEntry` is not found, previously was `ErrorException`.
+- Change return type on `addData!` convenience wrappers to only return new `BlobEntry`.
+- Fix `addBlob!` calls for `FolderStore` and `InMemoryBlobStore` to use `BlobEntry.originId` and not previous bug `entry.id`.
 - Close long running serialization redo (#590) using only JSON3.jl and StructTypes.jl going forward.
 - Standardize BlobEntry=>Blob naming of functions, and keeping convenience wrappers `{get,add,update,delete}Data[!]`.
 - Consolidate to only one `BlobEntry` definition, dropping use of `AbstractBlobEntry`.
