+### What's changed in v0.1.2
+
+* chore: Delete CHANGELOG.md (generated by each release) (by @patrickleet)
+
+* fix: use chart's env: key, not extraEnvVars:, for CF_API_TOKEN injection (by @patrickleet)
+
+  The external-dns Helm chart (v1.x) ignores extraEnvVars; environment
+  variables on the controller pod are configured via the top-level env:
+  array. The previous template wrote extraEnvVars and produced a pod
+  without CF_API_TOKEN set, crashing with:
+
+    failed to initialize cloudflare provider:
+    invalid credentials: key & email must not be empty
+
+  even when the cloudflare-api-token Secret was correctly populated by
+  the ExternalSecret integration. Fixed by switching the values key.
