do you mean about the consistent sampling ? (if yes, then maybe asking @jackshirazi might be relevant), or for marking the jmx gatherer as deprecated with #2034 ? The latter is only a documentation change for now, but if you plan to include it you can add the following:

JMX Gatherer

  • JMX Gatherer is now deprecated in favor of JMX Scraper
    (#2034)

I believe #2022 is a breaking change as in the edge case it covers, sampling will cascade correctly. But it's actually a bugfix. Nothing else that I know about is a notifiable change

I meant #2033

However, this should be included in the release notes as users of jmx-scraper with the following configuration will see changes in captured metrics:
otel.jmx.target.source = auto (default)
otel.jmx.target.system with jetty
