+## 1.77.8
+
+* No user-visible changes.
+
+## 1.77.7
+
+* Declarations that appear after nested rules are deprecated, because the
+  semantics Sass has historically used are different from the semantics
+  specified by CSS. In the future, Sass will adopt the standard CSS semantics.
+
+  See [the Sass website](https://sass-lang.com/d/mixed-decls) for details.
+
+* **Potentially breaking bug fix:** `//` in certain places such as unknown
+  at-rule values was being preserved in the CSS output, leading to potentially
+  invalid CSS. It's now properly parsed as a silent comment and omitted from the
+  CSS output.
+
+## 1.77.6
+
+* Fix a few cases where comments and occasionally even whitespace wasn't allowed
+  between the end of Sass statements and the following semicolon.
+
 ## 1.77.5
 
 * Fully trim redundant selectors generated by `@extend`.
