All notable changes to this project will be documented in this file.

## [Unreleased]

## [1.3.0] - 2023-05-01

* **New Features**
  * [CLIENT-2099] Support boolean particle type.
  * [CLIENT-2320] Implement `std::convert::TryFrom<aerospike::Value>` for each variant. Resolves #124. Refer to the mentioned ticket for the use case.
  * [CLIENT-2321] Support queries and scans not sending a fresh message header per partition in server v6+.

* **Bug Fixes**
  * Fixed large integers packing when encoding to messagepack. Thanks to [Babur Makhmudov](https://github.com/bobs4462)
  * Fixed Float serialization. Thanks to [Jonas Breuer](https://github.com/jonas32)

* **Improvements**
  * Fix tests failing without the `AEROSPIKE_HOSTS` environment variable set. Now they use `localhost` by default.
  * Fix a few compiler warnings and remove a few unused struct fields.

## [1.2.0] - 2021-10-22

* **New Features**
  * Support Aerospike server v5.6+ expressions in Operate API. Thanks to [Jonas Breuer](https://github.com/jonas32)

* **Bug Fixes**
  * Fix for buffer size when using CDT contexts. Thanks to [Jonas Breuer](https://github.com/jonas32)

## [1.1.0] - 2021-10-12
This version of the client drops support for the older server versions without changing the API. `ScanPolicy.fail_on_cluster_change`, `ScanPolicy.scan_percent` and `BasePolicy.priority` are deprecated for the Scan operations and will not be sent to the server. They remain in the API to avoid breaking the API.

* **New Features**
  * Support Aerospike server v5.6+ server authentication.
  * Support Aerospike server v5.6+ Scan protocol for simple cases.

## [1.0.0] - 2020-10-29

* **Bug Fixes**
  * Client.is_connected() returns true even after client.close() is called. [(#87)](https://github.com/aerospike/aerospike-client-rust/pull/87)

* **New Features**
  * BREAKING CHANGE: Replace predicate expressions with new Aerospike Expression filters. Aerospike Expression filters give access to the full data type APIs (List, Map, Bit, HyperLogLog, Geospatial) and expanded metadata based filtering, to increase the power of filters in selecting records. This feature requires server version 5.2.0.4 or later. See [API Changes](https://www.aerospike.com/docs/client/rust/usage/incompatible.html#version-1-0-0) for details. [(#80)](https://github.com/aerospike/aerospike-client-rust/issues/80) Thanks to [@jonas32](https://github.com/jonas32)!
  * Support operations for the HyperLogLog (HLL) data type. [(#89)](https://github.com/aerospike/aerospike-client-rust/issues/89) Thanks to [@jonas32](https://github.com/jonas32)!
  * Serde Serializers for Record and Value objects. [(#85)](https://github.com/aerospike/aerospike-client-rust/pull/85) Thanks to [@jonas32](https://github.com/jonas32)!

## [0.6.0] - 2020-09-11

    * Added missing list operations, list policies, and ordered lists.
