APM Portal access and ECMAScript compatibility

I notice that ECMAScript (ES13) is supported as stated in version 21.1 release note

https://techdocs.f5.com/en-us/bigip-21-1-0/big-ip-release-notes/big-ip-new-features.html#portal-access-ecmascript-es13-support-for-modern-javascript-applications

 

As I know, latest version in 17.1 can also use the latest cache-fm-Modern.js file. Does it imply that latest version in 17.1, say 17.1.3.2, also support ECMAScript (ES13)?

    Hello Alex_Ng​ 

    Have you by chance submitted a support case for this instance? If not I would suggest doing a general assistance case, this will not only allow you to get a direct answer but they will be able to put in for an update to these support articles. 

    Thanks
