CHANGELOG.md

@@ -22,6 +22,7 @@ As of v3.0.0 this project adheres to [Semantic Versioning](http://semver.org/).
 - Penalties must now be changed using the `\grechangecount` command.  See GregorioRef and [UPGRADE.md](UPGRADE.md) for details (for the change request, see [#1021](https://github.com/gregorio-project/gregorio/issues/1021)).
 - `\greemergencystretch` must now be set by changing `emergencystretch` using `\grechangedim` instead of redefining the macro.
 - An isolated stropha will now be considered part of the previous neume group and line breaks will be prevented at that point.  In order to force a line break there, use a breaking space such as `/` before the stropha in gabc.  See [#1056](https://github.com/gregorio-project/gregorio/issues/1056).
+- `interwordspacetext` and it's related distances have been redefined to be smaller and dependent on a font based distance (`ex`).  They are also no longer scale with the staff size by default.  See [#1036](https://github.com/gregorio-project/gregorio/issues/1036) & [gregoriot-test#208](https://github.com/gregorio-project/gregorio-test/pull/208).
