build platform / compiler updates for 18.3 planned ?

[Baesken, Matthias]

Hello,

https://wiki.openjdk.java.net/display/Build/Supported+Build+Platforms

states the list  of  supported build platforms/compilers  (for example for 9).

Are there  compiler updates planned  for the  18.3  release  ?
Especially is there a switch on Windows planned (from 2013SP4  to a new version of VS ) ?


Thanks and Regards, Matthias
