Spring Cloud uses the name of the London Underground station in the UK to name it, and releases the iterative version in the form of the letter AZ of the station name in turn. SpringCloud is a comprehensive project composed of many sub-projects, and each sub-project has a different release rhythm. In order to manage the version dependency between Spring Cloud and each sub-project, a list is released, which includes the sub-project version corresponding to a certain Spring Cloud version. In order to avoid confusion between the SpringCloud version number and the sub-project version number, == SpringCloud version uses names instead of version numbers. The names of these versions use the names of London Underground stations, corresponding to the time sequence of the versions according to the alphabetical order. == For example, Angel is the first version and Brixton is the second version. When the release content of Spring Cloud reaches a critical point or a major bug is resolved, a "service releases" version, referred to as the SRX version, will be released. For example, Greenwich.SR2 is the second SRX version of the Greenwich version released by Spring Cloud.
