Docs: HugeGraph 1.3.0 Release Notes

Mon, 01 Jan 0001 00:00:00 +0000

运行环境/版本说明

优先在 hugegraph/toolchain/commons软件中使用 Java 11, 此次是这些模块最后一次主版本兼容 Java 8 了。(computer 则仅支持 Java11)
另外相比 Java11, 使用 Java8 会失去一些安全性的保障，我们推荐生产或对外网暴露访问的环境使用 Java11 并开启 Auth 权限认证

1.3.0 是最后兼容 Java 8 的版本，在 1.5.0 开始就会全面使用 Java 11 (除client外).

PS: 未来 HugeGraph 组件的版本会朝着 Java 11 -> Java 17 -> Java 21 演进

hugegraph

在此次版本中我们修复了一些 SEC 相关的问题，如果是线上或者对外服务请升级到最新版本 + 开启权限认证

Docs: HugeGraph 1.2.0 Release Notes

Mon, 01 Jan 0001 00:00:00 +0000

Java version statement

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

Consider using Java 11 in hugegraph/hugegraph-toolchain/hugegraph-commons, also compatible with Java 8 now.
hugegraph-computer required to use Java 11, not compatible with Java 8 now!

v1.2.0 是倒数第二个兼容 Java8 的大版本, 到 1.5.0 PD/Store 正式合入 master 后标志着 Java8 兼容的正式终结 (除 Client 外所有组件都将以 Java 11 作为基准，然后逐步迈向 Java17/21).
