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 chapter in addition to any version-specific upgrade instructions outlined here.

2.27.0

Full release notes

Highlights:

• 2.27.0 Introduced a new upgrade tool to help migrating your instance to a newer version.
• The client and broker now use SLF4J for their logging API.
• The broker distribution now uses Log4J 2 as its logging implementation.

Upgrading from older versions

Client applications wanting logging will now need to supply an appropriate SLF4J-supporting logging implementation configured appropriately for their needs. See client application logging for more information plus an example around using Log4J 2.

The broker distribution now includes and configures Log4J 2 as its logging implementation, see logging for more details. If upgrading an existing broker instance rather than creating a new instance, some configuration etc updates will be necessary for the brokers existing instance /etc and /bin files.

You can use the new upgrade helper tool from the newly downloaded broker to refresh various configuration files and scripts for an existing broker instance. The broker.xml and data are left in place as-is.

You should back up your existing broker instance before running the command.

The command can be executed by running ./artemis upgrade <path-to-your-instance> from the new downloaded broker home.

Note:

Most existing customisations to the old configuration files and scripts will be lost in the process of refreshing the files. As such you should compare the old configuration files with the refreshed ones and then port any missing customisations you may have made as necessary. The upgrade command itself will copy the older files it changes to an old-config-bkp. folder within the instance dir.

Similarly, if you had customised the old logging.properties file you may need to prepare analogous changes for the new log4j2.properties file.

Note also that brokers configuration-file-refresh-period broker.xml setting no longer covers logging configuration refresh. Log4J 2 has its own configuration reload handling, configured via the monitorInterval property within the Log4J configuration file itself. The default <instance>/etc/log4j2.properties file created has a 5 second monitorInterval value set to align with the prior default broker behaviour.

Manual update

Alternatively, rather than using the upgrade helper command as outlined above, you can instead perform the update manually, following the general upgrading procedure plus the additional steps below:

1. The new <instance>/etc/log4j2.properties file should be created with Log4J 2 configuration. The file used by the "artemis create" CLI command can be downloaded from: log4j2.properties
2. The old <instance>/etc/logging.properties JBoss Logging configuration file should be deleted.
3. Related startup script or profile cleanups are needed: a diff file demonstrating the changes needed since 2.26.0 is available here for *nix or here for Windows.

2.26.0

Full release notes

Highlights:

• Bug fixes and improvements

Upgrading from older versions

1. We removed the *-all clients from ./lib/client in the assembly as part of ARTEMIS-4006. If you use these libraries they can be found at Maven Central, please refer to the client class path documentation for more information.
2. We removed ActiveMQ-Artemis rest as part of 2.26.0. If you still require activemq rest you can still have access to its latest version at Maven central. You can still follow the steps on Rest from any previous documentation, however you should stop using the module as it will not be maintained any more.
3. We removed web content from distribution and redirected to the console web requests with the root target as part of ARTEMIS-3980. If you used to customize the index page or to add custom content in the web folder please refer to the web-server documentation for more information on disabling the redirect and enabling the web content.

2.25.0

Full release notes

Highlights:

• Improvement on Paging Flow Control
• Many other bug fixes and improvements

2.24.0

Full release notes

Highlights:

• Streamlined page caches and files are just read into queues without the need of soft caches.

Upgrading from older versions

1. Due to ARTEMIS-3851 the queue created for an MQTT 3.x subscriber using CleanSession=1 is now non-durable rather than durable. This may impact security-settings for MQTT clients which previously only had createDurableQueue for their role. They will now need createNonDurableQueue as well. Again, this only has potential impact for MQTT 3.x clients using CleanSession=1.

2. Due to ARTEMIS-3892 the username assigned to queues will be based on the validated user rather than just the username submitted by the client application. This will impact use-cases like the following:

   1. When login.config is configured with the GuestLoginModule which causes some users to be assigned a specific username and role during the authentication process.
   2. When login.config is configured with the CertificateLoginModule which causes users to be assigned a username and role corresponding to the subject DN from their SSL certificate.

   In these kinds of situations the broker will use this assigned (i.e. validated) username for any queues created with the connection. In the past the queue's username would have been left blank.

2.23.1

Full release notes

Highlights:

• ARTEMIS-3856 - Failed to change channel state to ReadyForWriting : java.util.ConcurrentModificationException

2.23.0

Full release notes.

Highlights:

• management operations for the embedded web server.
• JakartaEE 10 Support
• BugFix: High cpu usage on ReadWrite locks

2.22.0

Full release notes.

Highlights:

• The default producer-window-size on cluster-connection was changed to 1MB to mitigate potential OutOfMemoryErrors in environments with with high latency networking.

2.21.0

Full release notes.

Highlights:

• MQTT 5 is now supported.
• A new set of performance tools are now available to evaluate throughput and Response Under Load performance of Artemis
• Diverts now support multiple addresses
• Runtime configuration reloading now supports bridges.
• Paging can now be configured by message count.

Upgrading from older versions

1. Due to XML schema changes to correct an inaccurate domain name 2 files will need to be updated:

   1. etc/bootstrap.xml
   2. etc/management.xml

   In both files change the XML namespace from activemq.org to activemq.apache.org, e.g. in bootsrap.xml use:

   <broker xmlns="http://activemq.apache.org/schema">
   

   And in management.xml use:

   <management-context xmlns="http://activemq.apache.org/schema">
   

2. If you're using JDBC persistence then due to the changes in ARTEMIS-3679 you'll need to update your database. The column HOLDER_EXPIRATION_TIME on the NODE_MANAGER_STOREchanged from a TIMESTAMP to a BIGINT (or NUMBER(19) on Oracle). You will have to stop any broker that is accessing that table and either drop it or execute the proper ALTER TABLE statement for your database. If you drop the table then it will be automatically recreated when broker restarts and repopulated with a new, auto-generated node ID.

3. If you're using JGroups then due to the changes in ARTEMIS-2413 where JGroups was updated from 3.x to 5.x you will need to update your JGroups configuration. Many of the protocols have changed, and there's no automated tool to bring legacy configurations up to date so please refer to the JGroups documentation for more details on the new configuration. You can find example configurations in the JGroups repository (e.g. tcp.xml and udp.xml).

2.20.0

Full release notes.

Highlights:

• Java 11 is now required.

2.19.0

Full release notes.

Highlights:

• New ability to replay retained journal records via the management API.
• New environment/system property to set the "key" for masked passwords when using the default codec.
• Ability to disable message-load-balancing and still allow redistribution via the new OFF_WITH_REDISTRIBUTION type.
• MQTT session state can now be cleaned up automatically to avoid excessive accumulation in situations where client's don't clean up their own sessions.
• Distribute full Jakarta Messaging 3.0 client in the lib/client directory along with a new example of how to use it in examples/features/standard/queue-jakarta.

2.18.0

Full release notes.

Highlights:

• Dual Mirror support improving capabilities on AMQP Mirror for Disaster Recovery
• Journal Retention
• Replication integrated with Zookeeper
• Connection Routers
• Concurrency configuration for core bridges.
• XPath filter expressions (for parity with ActiveMQ "Classic").

Upgrading from older versions

1. Due to ARTEMIS-3367 the default setting for verifyHost on core connectors has been changed from false to true. This means that core clients will now expect the CN or Subject Alternative Name values of the broker's SSL certificate to match the hostname in the client's URL.

   This impacts all core-based clients including core JMS clients and core connections between cluster nodes. Although this is a "breaking" change, not performing hostname verification is a security risk (e.g. due to man-in-the-middle attacks). Enabling it by default aligns core client behavior with industry standards. To deal with this you can do one of the following:

   • Update your SSL certificates to use a hostname which matches the hostname in the client's URL. This is the recommended option with regard to security.
   • Update any connector using sslEnabled=true to also use verifyHost=false. Using this option means that you won't get the extra security of hostname verification, but no certificates will need to change. This essentially restores the previous default behavior.

   For additional details about please refer to section 3.1 of RFC 2818 "HTTP over TLS".

2. Due to ARTEMIS-3117 SSL keystore and truststores are no longer reloaded automatically. Previously an instance of javax.net.ssl.SSLContext was created for every connection. This would implicitly pick up any changes to the keystore and truststore for any new connection. However, this was grossly inefficient and therefore didn't scale well with lots of connections. The behavior was changed so that just one javax.net.ssl.SSLContext is created for each acceptor. However, one can still reload keystores & truststores from disk without restarting the broker. Simply use the reload management operation on the acceptor. This is available via JMX, the web console, Jolokia, etc.

   Here's an example curl command you can use with Jolokia to invoke the artemis acceptor's reload operation:

   curl --user admin:admin --header "Content-Type: application/json" --request POST --data '{"type":"exec", "mbean":"org.apache.activemq.artemis:broker=\"0.0.0.0\",component=acceptors,name=\"artemis\"", "operation":"reload"}' http://localhost:8161/console/jolokia/exec
   

   Of course you'll want to adjust the username & password as well as the broker and acceptor names for your environment.

3. The "rate" metric for queues was removed from the web console via ARTEMIS-3397. This was a follow-up from ARTEMIS-2909 in 2.16.0 (referenced in the upgrade instructions below). The "rate" metric mistakenly left visible on the web console after it was removed from the management API.

4. Due to ARTEMIS-3141, ARTEMIS-3128, & ARTEMIS-3175 the data returned for any "list" or "browse" management method which return message data, including those exposed via the web console, will have their return data truncated by default. This is done to avoid adverse conditions with large volumes of message data which could potentially negatively impact broker stability. The management-message-attribute-size-limit address-setting controls this behavior. If you wish to restore the previous (and potentially dangerous behavior) then you can specify -1 for this. It is 256 by default.

2.17.0

Full release notes.

Highlights:

• Message-level authorization similar to ActiveMQ 5.x.
• A count of addresses and queues is now available from the management API.
• You can now reload the broker's configuration from disk via the management API rather than waiting for the periodic disk scan to pick it up
• Performance improvements on libaio journal.
• New command-line option to transfer messages.
• Performance improvements for the wildcard address manager.
• JDBC datasource property values can now be masked.
• Lots of usability improvements to the Hawtio 2 based web console introduced in 2.16.0
• New management method to create a core bridge using JSON-based configuration input.
• Jakarta Messaging 2.0 & 3.0 artifacts for Jakarta EE 8 & 9 respectively.

2.16.0

Full release notes.

Highlights:

• Configurable namespace for temporary queues
• AMQP Server Connectivity
• "Basic" SecurityManager implementation 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

1. Due to 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:

      ./artemis user add --user guest --password guest --role admin
      

      Use this instead:

      ./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 and ARTEMIS-3010

2. Due to ARTEMIS-2909 the "rate" metric was removed from the management API for queues. In short, the org.apache.activemq.artemis.core.server.Queue#getRate method is for slow-consumer detection and is designed for internal use only.

   Furthermore, it's too opaque to be trusted by a remote user as it only returns the number of message added to the queue since the last time it was called. The problem here is that the user calling it doesn't know when it was invoked last. Therefore, they could be getting the rate of messages added for the last 5 minutes or the last 5 milliseconds. This can lead to inconsistent and misleading results.

   There are three main ways for users to track rates of message production and consumption (in recommended order):

   1. Use a metrics plugin. This is the most feature-rich and flexible way to track broker metrics, although it requires tools (e.g. Prometheus) to store the metrics and display them (e.g. Grafana).

   2. Invoke the getMessageCount() and getMessagesAdded() management methods and store the returned values along with the time they were retrieved. A time-series database is a great tool for this job. This is exactly what tools like Prometheus do. That data can then be used to create informative graphs, etc. using tools like Grafana. Of course, one can skip all the tools and just do some simple math to calculate rates based on the last time the counts were retrieved.

   3. Use the broker's message counters. Message counters are the broker's simple way of providing historical information about the queue. They provide similar results to the previous solutions, but with less flexibility since they only track data while the broker is up and there's not really any good options for graphing.

2.15.0

Full release notes.

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.

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.

Highlights:

• Management methods for an address' duplicate ID cache to check the cache's size and clear it

Upgrading from older versions

Version 2.13.0 added new 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
logger.org.apache.activemq.audit.message.handlers=AUDIT_FILE
logger.org.apache.activemq.audit.message.useParentHandlers=false

...

#Audit logger

2.10.0

Full release notes.

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.

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

Highlights:

• Support exporting metrics.

2.8.1

Full release notes.

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 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 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 for more details.

2.4.0

Full release notes.

Highlights:

• JMX configuration via XML rather than having to use system properties via command line or start script.
• Configuration of max frame payload length for STOMP web-socket.
• Ability to configure HA using JDBC persistence.
• Implement role-based access control for management objects.

Upgrading from 2.3.0

1. Create <ARTEMIS_INSTANCE>/etc/management.xml. At the very least, the file must contain this:

   <management-context xmlns="http://activemq.apache.org/schema"/>
   

   This configures role based authorisation for JMX. Read more in the Management documentation.

2. If configured, remove the Jolokia war file from the web element in <ARTEMIS_INSTANCE>/etc/bootstrap.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:

   <app url="console" war="console.war"/>
   

   Note: the Jolokia REST interface URL will now be at http://<host>:<port>/console/jolokia

2.3.0

Full release notes.

Highlights:

• Web admin console!
• Critical Analysis and deadlock detection on broker
• Support Netty native kqueue on Mac.
• Last-value queue 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:

   <app url="console" war="console.war"/>
   

2.2.0

Highlights:

• Scheduled messages with the STOMP protocol.
• Support for JNDIReferenceFactory and JNDIStorable.
