• bigquery:
  • The SQL types DATE, TIME and DATETIME are now supported. They correspond to
    theDate,Time andDateTime types in the newcloud.google.com/go/civil
    package.
  • Support for query parameters.
  • Support deleting a dataset.
  • Values from INTEGER columns will now be returned as int64, not int. This
    will avoid errors arising from large values on 32-bit systems.
• datastore:
  • Nested Go structs encoded as Entity values, instead of a
    flattened list of the embedded struct's fields. This means that you may now have twice-nested slices, eg.

    typeStatestruct {Cities  []struct{Populations []int  }}

  • Contexts no longer hold namespaces; instead you must set a key's namespace
    explicitly. Also, key functions have been changed and renamed.
  • The WithNamespace function has been removed. To specify a namespace in a Query, use the Query.Namespace method:

    q:=datastore.NewQuery("Kind").Namespace("ns")

  • All the fields of Key are exported. That means you can construct any Key with a struct literal:

    k:=&Key{Kind:"Kind",ID:37,Namespace:"ns"}

  • As a result of the above, the Key methods Kind, ID, d.Name, Parent, SetParent and Namespace have been removed.
  • NewIncompleteKey has been removed, replaced byIncompleteKey. Replace

    NewIncompleteKey(ctx,kind,parent)

    with

    IncompleteKey(kind,parent)

    and if you do use namespaces, make sure you set the namespace on the returned key.
  • NewKey has been removed, replaced byNameKey andIDKey. Replace

    NewKey(ctx,kind,name,0,parent)NewKey(ctx,kind,"",id,parent)

    with

    NameKey(kind,name,parent)IDKey(kind,id,parent)

    and if you do use namespaces, make sure you set the namespace on the returned key.
  • TheDone variable has been removed. Replacedatastore.Done withiterator.Done, from the packagegoogle.golang.org/api/iterator.
  • TheClient.Close method will have a return type of error. It will return the result of closing the underlying gRPC connection.
