+# Release history for fudgets
+
+## 0.18.3.1 -- 2022-03-14
+
+* Renamed `doRequest.hs` to `doRequestCmd.hs` to avoid a name clash
+  with `DoRequest.hs` on systems with case-insensitive file names.
+
+## 0.18.3 -- 2022-03-13
+
+* Although Fudgets dates back to the early 1990s, this is the first
+  release on Hackage.
