Hi, folks.
Today, cita-sdk-java 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.
Why the new version rule?
Community version CITA uses new version command method of YY.MM. X, where YY represents year, MM represents month, and X represents bug fix version number. In order to adapt to community version CITA, the community version of cita-sdk-java will use the version naming rules of Year.Month. X, which is similar to the version rules of Ubuntu.
今天，cita-sdk-java 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。
为什么采用新的版本规则？
社区版CITA 使用 YY.MM. X 新版命名方法，为了适应社区版CITA，cita-sdk-java 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。
