This blog post doesnt cover all interesting changes, at least for me.[0]
For me most interesting upcoming changes are
JEP: 352: Non_Volatile Mapped Byte Buffers, JEP 345: NUMA-Aware Memory Allocation for G1 and JEP 370: Foreign-Memory Access API (Incubator). Especially FMA api [1] examples seems most promising but shipped with panama and I am not sure about the maturity yet: https://github.com/zakgof/java-native-benchmark
I wonder how GraalVM stands in this picture that beside of being polyglot, it has AOT and auto vectorization futures and I dont know if those are already/will be shipped also with openJDK
