Bug Fixes

  • datastore: Ensure the datastore time is returned as UTC (#3521) (0e659e2)
  • datastore: increase deferred key iter limit (#2878) (7f1057a)
  • datastore: loading civil types in non UTC location is incorrect (#3376) (9ac287d)


  • Fix saving behavior for non-struct custom types which implement PropertyLoadSaver and for nil interface types.
  • Support DetectProjectID when using the emulator.


  • Adds Datastore Admin API.
  • Documentation updates.


  • DEADLINE_EXCEEDED is now not retried.
  • RunInTransaction now panics more explicitly on a nil TransactionOption.
  • PropertyLoadSaver now tries to Load as much as possible (e.g., Key), even if an error is returned.
  • Client now uses transport/grpc.DialPool rather than Dial.
    • Connection pooling now does not use the deprecated (and soon to be removed) gRPC load balancer API.
  • Doc updates
    • Iterator is unsafe for concurrent use.
    • Mutation docs now describe atomicity and gRPC error codes more explicitly.
    • Cursor example now correctly uses “DecodeCursor” rather than “NewCursor”
