 # Changelog
 
+## 1.0.1
+
+- Extended GitHub Actions testing range, 1.8 to 1.15.
+
+  NOTE: credo, dialyxir, and ex_doc are only configured for 1.15 or later.
+
+- Added DCO checking (we will require sign-offs moving forward).
+
+- Added Dependabot configuration and automerge.
+
+- Updated dependencies to the latest versions and verified dialyzer
+  cleanliness.
+
+- Undid the formatting when I enabled `force_do_end_blocks: true` in
+  `.formatter.exs`.
+
 ## 1.0.0
