 #### Improvements 🧹
 
+- Opacity 0 shapes no longer have a label mask which made any segment of connections going through them lower opacity [#1940](https://github.com/terrastruct/d2/pull/1940)
+
 #### Bugfixes ⛑️
 
 - Local relative icons are relative to the d2 file instead of CLI invoke path [#1924](https://github.com/terrastruct/d2/pull/1924)
