 # Changelog for [`deepseq` package](http://hackage.haskell.org/package/deepseq)
 
+## 1.4.6.0
+
+  * Remove instances for Data.Semigroup.Option for GHC >= 9.2
+    ([#62](https://github.com/haskell/deepseq/pull/62))
+
 ## 1.4.5.0
 
   * Add `GNFData` for URec
     This will enable deriving NFData instances for unboxed types
+  * Set `infixr 0` for `deepseq`
+    Makes infix use of 'deepseq' parse the same way as infix use of 'seq'
 
 ## 1.4.4.0 *Sep 2018*
