 ## Changelog
 
+### v2.1.0 (April 23, 2022)
+
+- __Feature:__ icssify now uses PostCSS 8+, and therefore supports plugins in the new format.
+
 ### v2.0.0 (August 23, 2020)
 
 - __Breaking:__ The CSS transform is now global by default, to better handle cases where CSS in a third-party module needs to be included in the bundle. This *should* not cause any issues, but it's possible that this might break some existing bundling setups unexpectedly, so it's technically a breaking change. Please file an issue if this change causes problems for you!
