## 2.1.1

**June 19, 2019**

### Compatibility

<table><colgroup><col> <col></colgroup><thead><tr><th>Software</th><th>Version</th></tr></thead><tbody><tr><td><p>Mule</p></td><td><p>4.1.1 and later</p></td></tr></tbody></table>

### Features

- JMS 2.0 shared subscription - Added support for having multiple consumers subscribe to a single
  topic. This functionality distributes the topic’s message load among all subscribers.

## 2.1.0

**April 16, 2019**

### Compatibility

<table><colgroup><col> <col></colgroup><thead><tr><th>Software</th><th>Version</th></tr></thead><tbody><tr><td><p>Mule</p></td><td><p>4.1.1 and later</p></td></tr></tbody></table>

### Features

- Redelivery policy options (maximum redeliveries and outcome) were added to the connector’s
  configuration.

### Fixed Issues

- When dealing with manual ACK, if the flow failed with an error, the message could be reprocessed
  indefinitely. This is now fixed by the addition of the **Redelivery Policy** configuration.

### Known Issues

- Automatic completion of queue/topic names, subscriptions and rules may not work in Design Center.

- Under some scenarios, users can get an `InterruptedException` error on the Mule app startup. This
  does not affect the proper operation. To get rid of this message, check the **Skip Connectivity
  Test** checkbox in the connector’s configuration.

## 2.0.3

**February 22, 2019**

### Compatibility

<table><colgroup><col> <col></colgroup><thead><tr><th>Software</th><th>Version</th></tr></thead><tbody><tr><td><p>Mule</p></td><td><p>4.1.1 and later</p></td></tr></tbody></table>

### Fixed Issues

- Connection leaks were fixed.

- The connector would stop receiving messages when the flow threw an error. This was fixed.

### Known Issues

- Automatic completion of queue and topic names, subscriptions, and rules may not work in Design
  Center.

## 2.0.2

**December 5, 2018**

### Compatibility

<table><colgroup><col> <col></colgroup><thead><tr><th>Software</th><th>Version</th></tr></thead><tbody><tr><td><p>Mule</p></td><td><p>4.1.1 and later</p></td></tr></tbody></table>

### Fixed Issues

- Previously, the connector leaked connections while publishing a message to a topic using the
  default caching strategy. The connector uses one or two JMS connections based on the
  configuration.

### Known Issues

- Automatic completion of queue or topic names, subscriptions, and rules may not work in Design
  Center.

- In Design Center, the Live View feature does not work for most operations. In addition to this,
  the application log may be flooded with several `Could not serialize object` errors.

## 2.0.1

**October 23, 2018**

### Compatibility

<table><colgroup><col> <col></colgroup><thead><tr><th>Software</th><th>Version</th></tr></thead><tbody><tr><td><p>Mule</p></td><td><p>4.1.1 and later</p></td></tr></tbody></table>

### Fixed Issues

- Manual ACK not working - Previously, when attempting to do a manual acknowledge of a message, the
  connector would lock the flow. This was now fixed, and doing this works as expected.

### Known Issues

- Automatic completion of queue and topic names, subscriptions and rules may not work in Design
  Center.

- In Design Center, the Live View feature will not work for most operations. In addition to this,
  the application log may be flooded with several `Could not serialize object` errors.

- The connector leaks connections while publishing a message to a topic using the default caching
  strategy. As a workaround, configure the connector to disable the caching strategy.

## 2.0.0

**May 28, 2018**

### Compatibility

<table><colgroup><col> <col></colgroup><thead><tr><th>Software</th><th>Version</th></tr></thead><tbody><tr><td><p>Mule</p></td><td><p>4.1.1 and later</p></td></tr></tbody></table>

### Features

- Added support for Mule 4.

### Known Issues

- Automatic completion of queue and topic names, subscriptions, and rules may not work in Design
  Center.

- In Design Center, the Live View feature does not work for most operations. In addition to this,
  the application log may be flooded with several `Could not serialize object` errors.

- The connector leaks connections while publishing a message to a topic using the default caching
  strategy. As a workaround, configure the connector to disable the caching strategy.
