Version 3.0.0

--publish-command may now be used for private packages, allowing xyz to be configured to publish to a destination other than an npm registry (Docker Hub, for example). Previously xyz would run npm publish only for public packages, but the publish command (which defaults to npm publish) is now run unconditionally. Provide a publish command (such as : or true) to prevent xyz from running npm publish. #41

Commands provided via --publish-command may now refer to the VERSION and PREVIOUS_VERSION environment variables. #41

Touched but otherwise unchanged files are no longer considered unstaged changes. #43

xyz now includes a Bash implementation of npm's semver --increment functionality. The implementation is only slightly more complex than the code which determined the path to the semver executable, and will almost certainly prove less troublesome. #45

pre{major,minor,patch,release} increments are now fully supported. #45
