+## 1.69.7
+
+### Embedded Sass
+
+* In the JS Embedded Host, properly install the x64 Dart Sass executable on
+  ARM64 Windows.
+
+## 1.69.6
+
+* Produce better output for numbers with complex units in `meta.inspect()` and
+  debugging messages.
+
+* Escape U+007F DELETE when serializing strings.
+
+* When generating CSS error messages to display in-browser, escape all code
+  points that aren't in the US-ASCII region. Previously only code points U+0100
+  LATIN CAPITAL LETTER A WITH MACRON were escaped.
+
+* Provide official releases for musl LibC and for Android.
+
+* Don't crash when running `meta.apply()` in asynchronous mode.
+
+### JS API
+
+* Fix a bug where certain exceptions could produce `SourceSpan`s that didn't
+  follow the documented `SourceSpan` API.
+
 ## 1.69.5
 
 ### JS API
