### What’s New

- Added metadata for using policies in Agent Fabric.

## 1.1.0

**July 29, 2022**

### What’s New

- The policy definition and policy implementation file are now separate. This enables stronger
  validations for policy configuration parameters.

### New Features and Enhancements

- Flex support for the Policy.

## 1.0.5

**November 10, 2021**

### Fixed issues

- Fixed an issue where an authentication object was incorrectly cached.

## 1.0.4

**November 20, 2020**

### Minimum Mule Version

**Mule 4.1.0**

### Fixed issues

- When upgrading CloudHub Runtime version, policies that have the persistent cache enabled failed to
  deserialize elements.

## 1.0.3

**Apr 30, 2020**

### Minimum Mule Version

**Mule 4.1.0**

### Fixed issues

- A `ClassCastException` error occurred when another policy added a response header to the payload.
  This issue is now resolved.

## 1.0.2

**September 12, 2019**

### Minimum Mule Version

**4.1.0**

### Fixed Issues

- An Object Store repeatedly fails to store an event, resulting in a stack overflow.

## 1.0.1

**April 26, 2019**

### Minimum Mule Version

**4.1.0**

### Fixed Issues

- Previous version incompatible with Mule Runtime 4.2.0 and greater.

- An error occurred when internal parameters were serialized. This is because these parameters are
  not serializable.

- During a cache hit, the loaded event was using the old context, such as event Id and correlation
  Id), resulting in failed error handling and feedback loop.

### Known Issues

- Upgrading from a previous policy version invalidates the existing cache.

## 1.0.0 - Deprecated

**July 03, 2018**

### Compatibility

- v1.0.0 is compatible with v4.1.x and not compatible with v4.2.0 and greater of Mule Runtime.
