 ### Fixed
 - A two-line initial on a two-line score no longer generates an error (see [#1139](https://github.com/gregorio-project/gregorio/issues/1139)).
 - Staff lines after a two-line initial should now be sized correctly in a more consistent way (see [#1141](https://github.com/gregorio-project/gregorio/issues/1141)).
-
+- In rare cases, the very last bar or glyph of a score could appear alone at the beginning of the final line (see [#1152](https://github.com/gregorio-project/gregorio/issues/1152)).
