Hi, folks.

On the special day, we have a special Valentine's day. At present, we still have to face the challenge of virus, but we accept the challenge and will complete it.

Today, with your support and our efforts, CITA released version 20.2.0. In this version, we adopt a new version naming rule, that is, the version command method of YY.MM. X, where YY represents year, MM represents month, and X represents bug fix version number.

Finally, may the world be peaceful, the country peaceful and the people safe, and everyone happy and healthy!

Why the new version rule?
In order to meet more customized needs of customers, we started the commercial version plan of CITA. The commercial version of CITA will continue to use the original version naming rules, so the community version of CITA will use the version naming rules of Year.Month. X, which is similar to the version rules of Ubuntu.

在这段特殊的日子里，我们迎来了一个特殊的情人节。当下我们还要面对病毒的挑战，但我们接受挑战，亦会完成挑战。
也是今天，在大家的支持与努力下，CITA 发布 20.2.0 版本。在这个版本中，我们采用了新的版本命名规则，即采用 YY.MM.X 的版本命令方法，YY 表示年，MM 表示月，X 表示修订号。

最后，愿 天下太平，国泰民安 ，所有人幸福安康！

为什么采用新的版本规则？
为了满足客户更多的定制化需求，我们开始了 CITA 的商业版本计划，CITA 的商业版本将继续沿用原来的版本命名规则，所以 CITA 的社区版本将启用 年.月.X 的版本命名规则，这有点类似 Ubuntu 的版本规则。
