Purpose

Description
Several updates before releasing Halstack 14:

• Removed DxcBox component from Halstack Design System.
• useToast improved. The returned object is now memorized to avoid unnecessary renders inside components, hooks, etc.
• Included a toast inside the Halstack site to notify users about new available library versions.
• Theme generator updated with the most recent tokens. Also, the theme generator now uses our breadcrumbs instead of the custom ones.
• Fixed an issue with the data grid inside the theme generator.
• Theme page updates.
• Removed unnecessary import React from "react"; from every affected file.
• Applied prettier on every file.
• Updated component status in the site.
