Change Log

* Added `use_manual_address` client option.
* Added `schema.has_index` and `index.has_field` methods.

* **v1.2.0** (2018-12-21)
* **Compatible with Pilosa 1.2**
* Added `track_existence` index option.
* Added `not_` index method to support `Not` queries. The corresponding index must be created with `track_existence=True`.

* Added support for roaring importing `RowIDColumnID` with timestamp data.
* Added support for clear imports. Pass `clear=True` to `client.import_field` to use it.

* Compatible with Pilosa 1.0.
* Added `shards` option to `client.query` which allows limiting a query to be run for the specified shards.
* Removed all deprecated code.
* Following terminology was changed:
* frame to field
* bitmap to row
* bit to column
* slice to shard
* Removed `Field` type and renamed `Frame` to `Field`.
* There are three types of fields:
* Set fields to store boolean values (default)
* Integer fields to store an integer in the given range.
* Time fields which can store timestamps.

* **Removed** Row and column labels.
* **Removed** Index options.

* Customizable CSV timestamp format (Contributed by lachlanorr).
* **Deprecation** Row and column labels are deprecated, and will be removed in a future release of this library. Do not use `column_label` field when creating `Index` objects and do not use `row_label` field when creating `Frame` objects for new code. See: https://github.com/pilosa/pilosa/issues/752 for more info.

* **v0.5.0** (2017-08-03):
* Supports importing data to Pilosa server.
* Failover for connection errors.
* More logging.
* Introduced schemas. No need to re-define already existing indexes and frames.
