+## 1.17.3
+
+* Fix an edge case where slash-separated numbers were written to the stylesheet
+  with a slash even when they're used as part of another arithmetic operation,
+  such as being concatenated with a string.
+
+* Don't put style rules inside empty `@keyframes` selectors.
+
 ## 1.17.2
 
+* Deprecate `!global` variable assignments to variables that aren't yet defined.
+  This deprecation message can be avoided by assigning variables to `null` at
+  the top level before globally assigning values to them.
+
+### Dart API
+
 * Explicitly mark classes that were never intended to be subclassed or
   implemented as "sealed".
