 - Windows installer will check more locations for old installations to remove.
 - Height of the porrectus have been altered (first note moved up, second also moved up when second ambitus is more than one) so that they are more coherent with the punctum height. The porrectus stroke drawings have also been slightly altered to be slightly thinner and sharper around the bottom note (see [#858](https://github.com/gregorio-project/gregorio/issues/858)).
 - When a syllable is preceeded by a punctum mora, gregorio now ignores the punctum mora in the spacing of the syllables by default, and also adds a custom space (defaulting to 0). You can change this behavior with `\gresetshiftaftermora{}`, see GregorioRef for its arguments. To balance the output, space before a punctum mora has been made slightly thinner, more in line with old Solesmes books.

See GregorioRef for details (for the change request, see [#756](https://github.com/gregorio-project/gregorio/issues/756)).
 - Automatic line breaks before a `<eu>` block may be made ragged by using `\gresetbreakbeforeeuouae{ragged}`.  See GregorioRef for details (for the change request, see [#764](https://github.com/gregorio-project/gregorio/issues/764)).
 - The ability to typeset simple slurs.  See GregorioRef for details (for the change request, see [#776](https://github.com/gregorio-project/gregorio/issues/776)).
-- More control over the alignment of the annotation.  You can now set either the first line or the last line of the annotation as the controling line with `\gresetannotationby{firstline}` and `\gresetannotationby{lastline}` respectively.  Additionaly, within the line you can specify the top, baseline, or bottom of the line as the alignment point with `\gresetannotationvalign{top}`, `\gresetannotation{baseline}`, and `\gresetannotationvalgin{bottom}` respectively.  Default behavior is baseline of the top line (as it was before).  These alignment controls are applied before `annotationraise` is taken into account.
