+- `list_standard_documents` was removed, its functionality can be replace by
+  calling `list_records` and passing the nsid as "standard.site.document"
+
 ### Changed
 
 - All functions now use `prepend_header` instead of `set_header`.
 - Renamed `did.DidError` to `did.ParseError`
 - Rename `did.InvalidFormat` to `did.InvalidSyntax`
 - Rename `handle.InvalidFormat` to `handle.InvalidSyntax`
-- `resolve_handle` now takes a `handle.Handle` as parameter instead of a string
+- `resolve_handle` and `resolve_well_known_did` now take a `handle.Handle` as
+  parameter instead of a regular `String`
+- `resolve_handle` now takes a `handle.Handle` as parameter instead of a `String`
+- Functions now take a parsed `nsid.Nsid` as the `collection` parameter
