New features:

• Full support for profiling Java 23. This update is required if you profile virtual threads or perform async sampling.
• Added support for Hibernate 6.​6

Bug fixes:

• Virtual thread profiling was broken on recent OpenJ9 JVMs

New features:

• Security change: If the "address" option is not specified for the -agentpath parameter, the JProfiler agent will only listen on the loopback interface
• Security change: By default, the command line utility jpenable will now prepare a JVM for profiling in such a way that only local connections are allowed. jpenable has a new -a option to specify a listening address instead.
• Security change: Integration wizards will no longer suggest to configure unencrypted direct TCP connections to remote machines but use SSH connections by default
• Security change: The default connection type of a new profiling session is now "Local TCP connection". The old remote TCP connection is discouraged but is still available with the "Unsecured TCP connection" connection type.

Bug fixes:

• Connecting to a Docker or Kubernetes container did not work if the home directory was mounted with the "noexec" option
