A new version for Actionscript 3 users has been published. Yes indeed, even in 2025 there're still many legacy (and even new) applications based on the the AIR and Flex frameworks.
This particular release fixes a vulnerability unique only in AS3 clients. For more details check the download page here.
Thanks for continuing to maintain the AS3 API. Even today there are projects and communities still running Flash/AIR (and Ruffle), so it’s really appreciated to see ongoing support. Great job & thanks again!
