How do you guys manage JVM upgrades for your Kotlin for JVM apps? Are there benefits to upgrading ASAP or does JetBrains recommend specific JVM per Kotlin version?

there's no recomended JVM version for Kotlin, so I use the latest LTS.
New JVM version come with new functionality (e.g. the Vector API or the new/safer Foreign Memory Management, a better Garbage Collector for your usecase) and often more speed but sometimes a takes a while for all the libs your app uses to catch on (more specifically e.g. Spring uses bytecode instrumentation, so in the past it often took 2-3 months for Spring to support a new JVM versions). Also newer JVM versions sometimes remove support for some older cryptographic libraries. That can be a hassle if your app still depends on them.
I tend to update to newer JVM as soon as possible, if there's no immidiate problem showing up, everying tends to work just fine.
