5.2.3 release

release v5.2.2

v5.2.1

* Pass method argument in DataFrameClient query()

v5.2.0

* Finally add a CHANGELOG.md to communicate breaking changes (influxdata#598)
* Test multiple versions of InfluxDB in travis
* Add SHARD DURATION parameter to retention policy create/alter
* Update POST/GET requests to follow verb guidelines from InfluxDB
  documentation

* Fix performance degradation when removing NaN values via line
  protocol (influxdata#592)
* Dropped support for Python3.4

v5.1.0

* Fix dataframe issues with dates
* doc: clarify that send_packet takes a list
* escape tag values that ends with backslash
* DataFrameClient: escape measurement names
* Remove UDP Precision Restrictions
* Allow connecting to influxdb running on a
  path on the server

v5.0.0

* Fixed failing tags match in get_points() on a ResultSet:
    - This is a breaking change. Older influxdb servers that
      do not return tags as fields are not compatible with
      this change. This would result in the get_points()
      filters no longer working.
* Added pool size parameter to client constructor
* Added ping method to the client.
* Added support for not including all fields when using
  the series helper.
* Fixed typo in Content-Type header.
* Data arg in write() can now be a single string.
* Added method close to InfluxDBClient class.
* Added chunked query support for DataFrameClient.

v4.1.1

* Space padded select-queries should now return DataFrames
* Update to newer pandas API
* Fixed issue where UDP line protocol sending fails due to
  an uninitialized variable

* Fixes for mutable default parameters in dataframe
* Fix for using from_DSN constructor with dataframe
* Better handle databases with spaces in the name
* Added chunk size parameter
* Performance improvements in make_lines
* Allow user-configurable number of retries when
  submitting request to the database

* Various DataFrame client fixes

* Improvements in timezone handling
