-Release 2.1.0 - ???? ??, 2020
------------------------------
+Release 2.1.0 - August 15, 2020
+-------------------------------
 
  This release features the following (compared to 2.0):
 
  - NSAC 2.1.
  - Support for empty custom properties ("--foo:;").
  - env() is now processed in computed values.
+ - The parsing is a bit more Windows-friendly. Previous versions produced
+   different whitespaces when parsing custom CSS rules for Windows and Unix.
+   That was enough to break some unit tests on Windows.
+
+ In short, 2.1.0 is a bit more spec-compliant and a good refinement over 2.0.
