+
+**Overview:**
+
+Fixed License Settings tab visibility for non-licensed product types and updated README with v0.5.x features.
+
+**Bug Fix:**
+
+- License Settings tab now only shows for Licensed Product and Licensed Variable Product types
+- Previously the tab was visible on all product types due to CSS `!important` override forcing `display: block`
+

+

+- `README.md` - Updated with complete feature documentation for v0.5.x features
