Aerospike

Features
- Geo predicates (`geo_within_geojson_region, geo_within_radius, geo_contains_geojson_point, geo_contains_point`) now allow an optional `index_type` parameter to allow querying lists/maps of geo objects.
- Add new `aerospike.INDEX_GEO2DSPHERE` index type to allow creation of secondary indexes on GeoJSON data.

Fixes
- Calling `connect()` twice on client causes seg fault. _CLIENT-691_
- `client.exists()` gives an exception when record doesn't exist _CLIENT-697_
- Documentation: Example for predicate has a typo. _CLIENT-709_
- Documentation: Add the `fail_on_cluster_change` to the Scan Policies
- Documentation: Add the `percent` option to the Scan Options

Features
- `client.operate_ordered(ns, set, key)` function which performs multiple bin operations on a record with a given key,
with the results being returned as a list of (bin-name, result) tuples. _CLIENT-651_

Fixes
- Wrong error message for empty Lua file registration. Now returns AEROSPIKE_ERR_LUA_FILE_NOT_FOUND with a message stating the file is empty. _CLIENT-664_
- Allow integer values for aerocircle queries _CLIENT-688_
- Fix memory leak in operate method when using Unicode Strings. _CLIENT-690_
- Incorporate [PR](https://github.com/aerospike/aerospike-client-python/pull/110) for typo fix in README.rst from raftelti
- Incorporate [PR](https://github.com/aerospike/aerospike-client-python/pull/100) for scan apply fix from hawka to allow empty py_args to `client.can_apply()`
- Incorporate [PR](https://github.com/aerospike/aerospike-client-python/pull/113) to terminate a scan if callback raises an exception from RonRothman

Features
- `aerospike.calc_digest(ns, set, key)` function added to get the digest for a key without requiring a client connection.

Fixes
- `get_many()` with list of 25000 keys or more would seg fault. Switch to heap allocation for requests > 20000 keys.
- `aerospike.null` was implemented as a type incorrectly. This caused pympler to crash after loading aerospike module.
- **Note:** Since it is now a type and not an object, to get an instance you need use `aerospike.null()`.
- Change maximum number of objects that can be serialized from 1024 to 4096 and raise an exception if this limit is bypassed.
- Use C client version 4.0.2 which includes a memory leak fix for `as_operations_new()`

Announcing the Python Client Release 2.0.0

This is a big release which adds support for **Python 3**.
The methods [`exists`](http://www.aerospike.com/apidocs/python/client.html#aerospike.Client.exists), [`get`](http://www.aerospike.com/apidocs/python/client.html#aerospike.Client.get), and [`select`](http://www.aerospike.com/apidocs/python/client.html#aerospike.Client.select) **now raise** a [`RecordNotFound`](http://www.aerospike.com/apidocs/python/exception.html#aerospike.exception.RecordNotFound) exception. In the past you always got back a [record tuple](http://www.aerospike.com/apidocs/python/client.html#aerospike-record-tuple) of (_key_, _meta_, _bins_), then had to check for `meta is not None` to identify a non-existent record.

Features
- **Python 3 compatible** (>= 3.4). _CLIENT-603_
- Upgraded to C client [4.0.0](http://www.aerospike.com/download/client/c/notes.html#4.0.0).
- Raise a [`RecordNotFound`](http://www.aerospike.com/apidocs/python/exception.html#aerospike.exception.RecordNotFound) exception when a record is not found. _CLIENT-533_
- [`aerospike.Client.is_connected()`](http://www.aerospike.com/apidocs/python/client.html#aerospike.Client.is_connected) tests the client’s connections to the nodes. _CLIENT-625_
- Added list operators to [`aerospike.Client.operate()`](http://www.aerospike.com/apidocs/python/client.html#aerospike.Client.operate). _CLIENT-641_
- Added the scan option [`include_ldt`](http://www.aerospike.com/apidocs/python/scan.html#scan-options). _CLIENT-609_
- Added the [`compression_threshold`](http://www.aerospike.com/apidocs/python/aerospike.html#aerospike.client) config param to the client. _CLIENT-626_
- Removed the deprecated classes `aerospike.Key`, `aerospike.LMap`, `aerospike.LSet`, `aerospike.LStack` . _CLIENT-394_

Fixes
- Fixed a bug where boolean items in a list got cast to integers by list operations. _CLIENT-632_
- Fixed issue 92 wrong exception raised by [`aerospike.LList.find_first`](http://www.aerospike.com/apidocs/python/llist.html#aerospike.LList.find_first). _CLIENT-607_
- Fixed enterprise edition tests. _CLIENT-642_
