+## 11.2.1 (2026-09-20)

+### Bug fixes
+
+- do not emit invalid minus unary operator (the browser discards values like calc(-(-12px))
+- improve rounding so it is more spec-compliant in edge cases
+- preserve invalid declarations with unary minus, instead of converting them to valid declarations
 
 ## 11.2.0 (2026-09-17)
