 ### Bugs
 1. [#61](https://github.com/influxdata/influxdb-client-python/issues/61): Correctly parse CSV where multiple results include multiple tables
 1. [#66](https://github.com/influxdata/influxdb-client-python/issues/66): Correctly close connection pool manager at exit
+1. [#69](https://github.com/influxdata/influxdb-client-python/issues/69): `InfluxDBClient` and `WriteApi` could serialized by [pickle](https://docs.python.org/3/library/pickle.html#object.__getstate__) (python3.7 or higher)
