Table 1. Deprecations, stabilizations, and removals at IBM MQ 9.4
Feature	Description
IBM MQ 9.4.0 release
Deprecation: Use of the Java security manager with IBM MQ Internet Pass-Thru	The use of the Java security manager with IBM MQ Internet Pass-Thru (MQIPT) is deprecated from February 16 2023, due to the Java security manager having been deprecated for removal in a future release of Java.
Deprecation: CMS keystores and stash files support for IBM MQ Java applications	For Long Term Support, CMS keystores and stash files for IBM MQ Java applications are deprecated from IBM MQ 9.4.0. The migration path is to move to PKCS#12 keystores and use the keystore password feature. Note: From IBM MQ 9.4.0, CMS keystores and stash files are not supported for configuring AMQP and MQTT channels with SSL/TLS. Use PKCS#12 and keystore passwords instead. For more information, see Setting up a key repository on AIX, Linux, and Windows and Telemetry channel configuration for channel authentication using TLS. For Continuous Delivery, CMS keystores and stash files for IBM MQ Java applications, AMQP and MQTT were deprecated from IBM MQ 9.3.4.
Deprecation: XL C/C++ for AIX® 16 compiler support on AIX	For Long Term Support, support for the XL C/C++ for AIX 16 compiler on AIX is deprecated from IBM MQ 9.4.0.

Removal: MQIPT certificate management commands	From IBM MQ 9.4.0, the following commands to manage certificates in MQIPT keystores are removed: mqiptKeycmd mqiptKeyman A new command, mqiptKeytool, can be used instead of mqiptKeycmd to manage certificates in MQIPT keystores. There is no replacement for mqiptKeyman. Users who wish to continue using a graphical tool for certificate management are encouraged to use PKCS#12 keystores which can be manipulated by any graphical certificate management tool available. For more information about the mqiptKeytool command, see mqiptKeytool (manage certificates). For more information about managing MQIPT keystores, see Managing MQIPT keystores.
Removal: runmqckm and strmqikm commands	From IBM MQ 9.4.0, the runmqckm and strmqikm commands are removed. The Manage SSL Certificates option in IBM MQ Explorer, which starts the strmqikm (iKeyman) GUI, is also removed. Users of the removed command line runmqckm tool should use the runmqakm, or the new runmqktool, command line tools. There is no replacement for the graphical strmqikm (iKeyman) tool. Users who wish to continue using a graphical tool for certificate management are encouraged to use PKCS#12 keystores, which can be manipulated by any graphical certificate management tool available. For more information, see runmqakm and runmqktool commands on AIX, Linux, and Windows and Working with SSL/TLS on AIX, Linux, and Windows.

Table 8. Deprecations, stabilizations, and removals at IBM WebSphere MQ 7.1
Feature	Description
IBM WebSphere MQ 7.1.0 initial release
Deprecation: CipherSpecs	A number of CipherSpecs are deprecated from IBM WebSphere MQ 7.5.0 Fix Pack 6.
Removal: /usr/lpp/mqm symbolic link	On AIX, before IBM WebSphere MQ 6.0, the product placed a symbolic link in /usr/lpp/mqm. The link ensured queue managers and applications migrated from versions before IBM WebSphere MQ 5.3 continued to work, without change. The link is not created in IBM WebSphere MQ 7.1.0 or later.
Removal: rtmqlnk and dltmqlnk commands	On UNIX and Linux, the crtmqlnk and dltmqlnk commands are removed at IBM WebSphere MQ 7.1.0. Before IBM WebSphere MQ 7.1.0, these commands created symbolic links in subdirectories of /usr. From IBM WebSphere MQ 7.1.0 onwards, you must use the setmqinst command instead.
Removal:/usr symbolic links	From IBM WebSphere MQ 7.1.0, on all UNIX and Linux platforms, the links from the /usr file system are no longer made automatically. In order to take advantage of these links, you must set an installation as the primary installation or set the links up manually.
Removal: amqmsrvn.exe process	On Windows, from IBM WebSphere MQ 7.1.0, the amqmsrvn.exe DCOM process is replaced by a Windows service, amqsvc.exe.
