Involving course, you can add components or design new ones. By design, Spartacus is modular and intensive so that you can consistently upgrade and benefits associated with the latest version of components.
sap Spartacus certification is grouped together as Angular your local library while we present new feature or fixes, you can take good thing about them right away. Of which is why we don't recommend that you fork the Spartacus project or copy/paste the source code if you want to build a new storefront but you create a new Angular App set up and add dependencies to Spartacus your local library. Patch and slight release of Spartacus probably should not break abiliyy and that we don't plan any new major release before the ending of the year so changing to the new libraries should not cause any problem with your store app.
