Keywords

A keyword is a variable that you can use to specify a package version number.

You can use keywords to automatically increment the value of the package build numbers, or set the package dependency to the latest version, or the latest released and promoted version.

Use the Keyword Example
LATEST to specify the latest version of the package dependency when you create a package version. 
1"dependencies": [ 
2   {
3      "package": "MyPackageName",
4      "versionNumber": "0.1.0.LATEST"
5   }
6]
NEXT to increment the build number to the next available for the package version. 
1"versionNumber": "1.2.0.NEXT"
RELEASED to specify the latest promoted and released version of the package dependency when you create a package version. 
1"dependencies": [
2   {
3    "package": "pkgB",
4    "versionNumber": "2.1.0.RELEASED"
5    }
