官方wiki的说明，称7.00会开启一个新的时代。
*另外6.00的时候，除了大量的游戏改动外，最重要的一点是冰蛙的上位。不知道这次会不会有什么游戏外的变化
The version numbers 6.89 up to 6.99 were skipped and do not exist. The next patch after 6.88 was 7.00, indicating a new start of an era in Dota.
- This is similar to what happened in 2005, when 6.00 was released. The versions numbers 5.85 to 5.99 were skipped, starting off with 6.00.
=============
既然直接变动大版本号，必然是有较为底层的机制性的变化
