# Versions

This chapter provides the following information for each release:
- A link to the full release notes which includes all issues resolved in the release.
- A brief list of "highlights" when applicable.
- If necessary, specific steps required when upgrading from the previous version. 
  - **Note:** If the upgrade spans multiple versions then the steps from **each** version need to be followed in order.
  - **Note:** Follow the general upgrade procedure outlined in the [Upgrading the Broker](upgrading.md) 
    chapter in addition to any version-specific upgrade instructions outlined here.

## 2.16.0

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12348718).

Highlights:
- Configurable namespace for temporary queues
- [AMQP Server Connectivity](amqp-broker-connections.md)
- "Basic" [`SecurityManager` implementation](security.md#basic-security-manager) that supports replication
- Consumer window size support for individual STOMP clients
- Improved JDBC connection management
- New web console based on Hawtio 2
- Performance optimizations (i.e. caching) for authentication and authorization
- Support for admin objects in the JCA resource adapter to facilitate deployment into 3rd-party Java EE application servers
- Ability to prevent an acceptor from automatically starting

#### Upgrading from older versions

Due to [ARTEMIS-2893](https://issues.apache.org/jira/browse/ARTEMIS-2893) the
fundamental way user management was implemented had to change to avoid data
integrity issues related to concurrent modification. From a user's perspective
two main things changed:

1. User management is no longer possible using the `artemis user` commands
   when the broker is **offline**. Of course users are still free to modify the
   properties files directly in this situation.
2. The parameters of the `artemis user` commands changed. Instead of using
   something like this:
   ```sh
   ./artemis user add --user guest --password guest --role admin
   ``` 
   Use this instead:
   ```sh
   ./artemis user add --user-command-user guest --user-command-password guest --role admin
   ```
   In short, use `user-command-user` in lieu of `user` and `user-command-password`
   in lieu of `password`. Both `user` and `password` parameters now apply to the
   connection used to send the command to the broker.
   
   For additional details see [ARTEMIS-2893](https://issues.apache.org/jira/browse/ARTEMIS-2893)
   and [ARTEMIS-3010](https://issues.apache.org/jira/browse/ARTEMIS-3010) 

## 2.15.0

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12348568).

Highlights:
- Ability to use FQQN syntax for both `security-settings` and JNDI lookup
- Support pausing dispatch during group rebalance (to avoid potential out-of-order consumption)
- Socks5h support

## 2.14.0

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12348290).

Highlights:
- Management methods to update diverts
- Ability to "disable" a queue so that messages are not routed to it
- Support JVM GC & thread metrics
- Support for resetting queue properties by unsetting them in `broker.xml`
- Undeploy diverts by removing them from `broker.xml`
- Add `addressMemoryUsagePercentage` and `addressSize` as metrics

#### Upgrading from older versions

This is likely a rare situation, but it's worth mentioning here anyway. Prior
to 2.14.0 if you configured a parameter on a `queue` in `broker.xml` (e.g.
`max-consumers`) and then later *removed* that setting the configured value you
set would remain. This has changed in 2.14.0 via ARTEMIS-2797. Any value that
is not explicitly set in `broker.xml` will be set back to either the static
default or the dynamic default configured in the address-settings (e.g. via
`default-max-consumers` in this example). Therefore, ensure any existing queues
have all the needed parameters set in `broker.xml` values before upgrading.

## 2.13.0

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12348088).

Highlights:
- Management methods for an address' duplicate ID cache to check the cache's size and clear it
- Support for [min/max expiry-delay](message-expiry.md#configuring-expiry-delay)
- [Per-acceptor security domains](security.md#per-acceptor-security-domains)
- Command-line `check` tool for checking the health of a broker
- Support disabling metrics per address via the [`enable-metrics` address setting](address-model.md#configuring-addresses-and-queues-via-address-settings)
- Improvements to the [audit logging](logging.md#configuring-audit-logging)
- Speed optimizations for the `HierarchicalObjectRepository`, an internal object used to store address and security settings

#### Upgrading from older versions

Version 2.13.0 added new [audit logging](logging.md#configuring-audit-logging)
which is logged at `INFO` level and can be very verbose. The
`logging.properties` shipped with this new version is set up to filter this out
by default. If your `logging.properties` isn't updated appropriately this audit
logging will likely appear in your console and `artemis.log` file assuming
you're using a logging configuration close to the default. Add this to your
`logging.properties`:

```
# to enable audit change the level to INFO
logger.org.apache.activemq.audit.base.level=ERROR
logger.org.apache.activemq.audit.base.handlers=AUDIT_FILE
logger.org.apache.activemq.audit.base.useParentHandlers=false

logger.org.apache.activemq.audit.resource.level=ERROR
logger.org.apache.activemq.audit.resource.handlers=AUDIT_FILE
logger.org.apache.activemq.audit.resource.useParentHandlers=false

logger.org.apache.activemq.audit.message.level=ERROR

## 2.10.0

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12345602).

This was mainly a bug-fix release with a notable dependency change impacting version upgrade.

#### Upgrading from 2.9.0

Due to the WildFly dependency upgrade the broker start scripts/configuration need to be adjusted after upgrading.

##### On \*nix

Locate this statement in `bin/artemis`:
```
WILDFLY_COMMON="$ARTEMIS_HOME/lib/wildfly-common-1.5.1.Final.jar"
```
This needs to be replaced with this:
```
WILDFLY_COMMON="$ARTEMIS_HOME/lib/wildfly-common-1.5.2.Final.jar"
```

##### On Windows

Locate this part of `JAVA_ARGS` in `etc/artemis.profile.cmd` respectively `bin/artemis-service.xml`:
```
%ARTEMIS_HOME%\lib\wildfly-common-1.5.1.Final.jar
```
This needs to be replaced with this:
```
%ARTEMIS_HOME%\lib\wildfly-common-1.5.2.Final.jar
```

## 2.9.0

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12345527).

This was a light release. It included a handful of bug fixes, a few improvements, and one major new feature.

Highlights:
- Support [exporting metrics](metrics.md).

## 2.8.1

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12345432).

This was mainly a bug-fix release with a notable dependency change impacting version upgrade.

#### Upgrading from 2.8.0

Due to the dependency upgrade made on [ARTEMIS-2319](https://issues.apache.org/jira/browse/ARTEMIS-2319) the
broker start scripts need to be adjusted after upgrading.

##### On \*nix

Locate this `if` statement in `bin/artemis`:
```
if [ -z "$LOG_MANAGER" ] ; then
 # this is the one found when the server was created
 LOG_MANAGER="$ARTEMIS_HOME/lib/jboss-logmanager-2.0.3.Final.jar"
fi
```
This needs to be replaced with this block:
```
if [ -z "$LOG_MANAGER" ] ; then
 # this is the one found when the server was created
 LOG_MANAGER="$ARTEMIS_HOME/lib/jboss-logmanager-2.1.10.Final.jar"
fi

WILDFLY_COMMON=`ls $ARTEMIS_HOME/lib/wildfly-common*jar 2>/dev/null`
if [ -z "$WILDFLY_COMMON" ] ; then
 # this is the one found when the server was created
 WILDFLY_COMMON="$ARTEMIS_HOME/lib/wildfly-common-1.5.1.Final.jar"
fi
```
Notice that the `jboss-logmanager` version has changed and there is also a new `wildfly-common` library.

Not much further down there is this line:
```
-Xbootclasspath/a:"$LOG_MANAGER" \
```
This line should be changed to be:
```
-Xbootclasspath/a:"$LOG_MANAGER:$WILDFLY_COMMON" \
```

##### On Windows

Locate this part of `JAVA_ARGS` in `etc/artemis.profile.cmd` respectively `bin/artemis-service.xml`:
```
-Xbootclasspath/a:%ARTEMIS_HOME%\lib\jboss-logmanager-2.1.10.Final.jar
```
This needs to be replaced with this:
```
-Xbootclasspath/a:%ARTEMIS_HOME%\lib\jboss-logmanager-2.1.10.Final.jar;%ARTEMIS_HOME%\lib\wildfly-common-1.5.1.Final.jar
```

#### Upgrading from 2.4.0

1. Due to changes from [ARTEMIS-1644](https://issues.apache.org/jira/browse/ARTEMIS-1644) any `acceptor` that needs to be
   compatible with HornetQ and/or Artemis 1.x clients needs to have `anycastPrefix=jms.queue.;multicastPrefix=jms.topic.`
   in the `acceptor` url. This prefix used to be configured automatically behind the scenes when the broker detected 
   these old types of clients, but that broke certain use-cases with no possible work-around. See 
   [ARTEMIS-1644](https://issues.apache.org/jira/browse/ARTEMIS-1644) for more details.

## 2.4.0

[Full release notes](https://issues.apache.org/jira/secure/ReleaseNote.jspa?projectId=12315920&version=12341540).

Highlights:
- [JMX configuration via XML](management.md#role-based-authorisation-for-jmx) rather than having to use system properties via command line or start script.
- Configuration of [max frame payload length for STOMP web-socket](protocols-interoperability.md#stomp-over-web-sockets).
- Ability to configure HA using JDBC persistence.
- Implement [role-based access control for management objects](management.md).

#### Upgrading from 2.3.0

1. Create `<ARTEMIS_INSTANCE>/etc/management.xml`. At the very least, the file must contain this:
   ```xml
   <management-context xmlns="http://activemq.org/schema"/>
   ```
   This configures role based authorisation for JMX. Read more in the [Management](management.md) documentation.
1. If configured, remove the Jolokia war file from the `web` element in `<ARTEMIS_INSTANCE>/etc/bootstrap.xml`:
   ```xml
   <app url="jolokia" war="jolokia.war"/>
   ``` 
   This is no longer required as the Jolokia REST interface is now integrated into the console web application.
   
   If the following is absent and you desire to deploy the web console then add:
   ```xml
   <app url="console" war="console.war"/>
   ```   
   **Note:** the Jolokia REST interface URL will now be at `http://<host>:<port>/console/jolokia`


## 2.3.0

- [Web admin console](management-console.md)!
- [Critical Analysis](critical-analysis.md) and deadlock detection on broker
- Support [Netty native kqueue](configuring-transports.md#macos-native-transport) on Mac.
- [Last-value queue](last-value-queues.md) for AMQP

#### Upgrading from 2.2.0

1. If you desire to deploy the web console then add the following to the `web` element in `<ARTEMIS_INSTANCE>/etc/bootstrap.xml`:
   ```xml
   <app url="console" war="console.war"/>
   ```
