 - Fixed a bug that could cause problems with headers/footers by generalizing the fix for fancyhdr (see [#1610](https://github.com/gregorio-project/gregorio/pull/1610) to work with any headers/footers. In particular, it fixes a similar problem with the `memoir` class. See [#1753](https://github.com/gregorio-project/gregorio/pull/1753).
 - Fixed some typos that would cause a handful of spaces to be scaled incorrectly. See [PR #1746](https://github.com/gregorio-project/gregorio/pull/1746).
 - Fixed a few bugs related to horizontal spacing around bars and clef changes. See issues [#1191](https://github.com/gregorio-project/gregorio/issues/1191), case 3 of [#1724](https://github.com/gregorio-project/gregorio/issues/1724), [PR #1743](https://github.com/gregorio-project/gregorio/pull/1743), and [#1745](https://github.com/gregorio-project/gregorio/issues/1745).
+- Fixed a bug in horizontal spacing when the first syllable consists of only a bar. See [PR #1741](https://github.com/gregorio-project/gregorio/pull/1741).
