JEP 442: Foreign Function and Memory API (Third Preview)
&gt; The JEP is a Preview Feature meaning the Foreign Function &amp; Memory API (hereafter &quot;FFM&quot;) will not be a final feature in JDK 21. I think some of us hoped it could make it into finality in 21. However, my personal opinion is that the API is very unlikely to change in any significant way and what we are seeing in 21 will be very close to the final FMM API.<p>One thing I really appreciate about Java and the JEP process is the careful attention to detail and avoid breaking changes. So if it takes a few extra cycles, I&#x27;m all in. It&#x27;s worth getting it right the first time.<p>FFS, stuff I downloaded from Node _5m ago_ is already deprecated.
