The 1.0.57 release of the Python client came out on December 9, 2015 and is available for download [here](https://github.com/aerospike/aerospike-client-python/releases/tag/1.0.57). It boasts a number of features and fixes:

Features

- Added `aerospike.null` to be used for removing bins with write operations. Using this value with an `aerospike.Client.put` is equivalent to calling [`aerospike.Client.remove_bin`](https://pythonhosted.org/aerospike/client.html#aerospike.Client.remove_bin) on that bin.
- Added a config param `strict_types` (default: `True`) for controlling whether the client does type checking for write operations. CLIENT-582, CLIENT-574
- Updated the documentation for [multi-ops](https://pythonhosted.org/aerospike/client.html#aerospike.Client.operate) and regarding [seed nodes](https://pythonhosted.org/aerospike/client.html#aerospike.Client.connect).

Fixes

- Fixed [Issue #91](https://github.com/aerospike/aerospike-client-python/issues/91), allowing -1L as a valid bin value. CLIENT-598
- Fixed the client to respect an explicit lua [`user_path`](https://pythonhosted.org/aerospike/client.html#aerospike.Client.udf_put) in its config. CLIENT-597
- Fixed the touch operation in [`aerospike.Client.operate`](https://pythonhosted.org/aerospike/client.html#aerospike.Client.operate) to not require _bin_ or _val_. CLIENT-584
- Allow bin names to be null-terminated bytearrays. CLIENT-581
- Fixed false-negative tests. CLIENT-602
