+* Bumped dependency bound for ansi-terminal
+
+2024-10-30 Laurent P. René de Cotret <laurent.decotret@outlook.com> 0.4.0

+* Removed dependency on `rematch` (#459). This means that certain functions 
+  are no longer exported: `shouldBe`, `shouldMatch`, `shouldContain`, 
+  `shouldNotContain`, and `expectThat`.

 * Bumped dependency bounds to support GHC 8.10.7 - GHC 9.10.1
