 ## Planned changes for upcoming release
 
 - Fix quad layer bug described in issue [#??]
+- Implement fixed number of segments on boundary edges / periodic edges?
 
 ### Fixed
 - Fixed bug in `Log.h` which resulted from the additional `static` declaration on `LOG_PROPERTIES` in commit [`5c2cebc`](https://github.com/FloSewn/TQMesh/commit/5c2cebc).
