GIT/SVN tag Management methodAdvantage, switching branch costs at any time is low, especially when Git manages the code.Disadvantage, the code merge workload is large if multiple versions need to be modified.There is only one branch, which is judged by the version information in the code.Advantages, the overall size of the code is small (only one code)Disadvantage, there will be a large number of branch statements where the version needs to be judgedThe solution I've summed upThe final solution
methods: git/svn tag management
Advantages: low branch switching costs at any time, especially when git manages code.Disadvantage: if multiple versions need to be modified, the code merging workload is heavy.There is only one branch, which can be determined based on version information in the code.
Advantage: The overall size of the code is small (only one piece of code is available)Disadvantages: there will be a large number of branch statements where you need to determine the versionMy summar
