Description

There are some situation that we want to update to specific version, to not latest angular version.

But, there are no description for how to update to specific angular version with ng update in update.angular.io and ng update reference. Caution: not “migrate only update”. I refer about update the installed version.

By the way, Acording to angular-cli/docs/specifications/update.md ,

Each package follows the convention of [@scope/]packageName[@version-range-or-dist-tag].

So we can use next command to update specific Angular version.

ng update @angular/cli@7.0.0 @angular/core@7.0.0

Is this above method that update to specific version is defined correctly? And this is a little hard to find how to update to specific version. I am so happy if there is documented at update.angular.io or ng update reference.

How about documenting how to update to specific angular version with ng update in update.angular.io and ng update reference?

ng update @angular/cli@7.0.0 @angular/core@7.0.0

The CLI API doc is in the CLI repo, https://github.com/angular/angular-cli/ I should probably do this, these use a different generation process that is a bit tricky.

please use ng update @angular/cli@^<major_version> @angular/core@^<major_version> instead. e.g. ng update @angular/cli@^7 @angular/core@^7. This means take the latest 7.x.x version and use that to update. In general we recommend that you use the latest patch version during update as it contains fixes we released since the initial major release.
