usage: rush change [-h] [-v] [-b BRANCH] Asks a series of questions and then generates a <branchname>-<timstamp>.json file in the common folder. The `publish` command will consume these files and perform the proper version bumps. Note these changes will eventually be published in a changelog.md file in each package. The possible types of changes are: MAJOR - these are breaking changes that are not backwards compatible. Examples are: renaming a public class, adding/removing a non-optional parameter from a public API, or renaming an variable or function that is exported. MINOR - these are changes that are backwards compatible (but not forwards compatible). Examples are: adding a new public API or adding an optional parameter to a public API PATCH - these are changes that are backwards and forwards compatible. Examples are: Modifying a private API or fixing a bug in the logic of how an existing API works. HOTFIX (EXPERIMENTAL) - these are changes that are hotfixes targeting a specific older version of the package. When a hotfix change is added, other changes will not be able to increment the version number.Enable this feature by setting 'hotfixChangeEnabled' in your rush.json. Optional arguments: -h, --help Show this help message and exit. -v, --verify Verify the change file has been generated and that it is a valid JSON file -b BRANCH, --target-branch BRANCH If this parameter is specified, compare current branch with the target branch to get changes. If this parameter is not specified, the current branch is compared against the "master" branch.
