The major difference between the current code and the reference (with knowledge cut-off on September 1, 2021) is that the actions object in the exported module has been updated from { prop: 'id', formatterArgs: { canUpdate } } to { prop: 'name' }. Additionally, there is a bug fix where it now calls the parent object's method instead of directly referencing methods within the props object inside an action.

As for potential optimizations, consider:

• Remove unnecessary imports if not necessary.
• Use ES6 class syntax instead of arrow functions when they're more readable, like you had done earlier in some parts.
• In cases where no custom validation is required, use default validators provided by Vue.js components which might have already optimized logic. For instance, this.$validator.isurl("") or similar could be used for URL input, rather than using raw regexes here.

Remember, these changes should depend on specific project requirements, so do additional validations and testing before applying them across the entire application.
