HugeGraph 1.2.0 Release Notes

Java version statement

v1.2.0:

  1. hugegraph, hugegraph-toolchain, hugegraph-commons consider use Java 11, also compatible with Java 8 now.
  2. hugegraph-computer required to use Java 11, not compatible with Java 8 now!

v1.2.0 may be the last major version compatible with Java 8, compatibility with Java 8 will totally end in v1.5 when PD/Store merged into master branch (Except for the java-client).

In the future, we will gradually upgrade the java version, Java 11 -> Java 17 -> Java 21.
