 ### Bug Fixes
 
-* add `cloudformation:List*` to default actions ([#45](https://github.com/observeinc/terraform-aws-lambda/issues/45)) ([313ffda](https://github.com/observeinc/terraform-aws-lambda/commit/313ffda9368be80b29dadc0c1588c0ab423d947f))
-* update s3_bucket_subscription module README with correct source location ([#44](https://github.com/observeinc/terraform-aws-lambda/issues/44)) ([eeec33f](https://github.com/observeinc/terraform-aws-lambda/commit/eeec33f2dc9a2e325b0bda01f72d7981ebf206a5))
+* **s3_bucket_subscription:** use `aws_arn` data source ([#50](https://github.com/observeinc/terraform-aws-lambda/issues/50)) ([129aa8b](https://github.com/observeinc/terraform-aws-lambda/commit/129aa8b867018389740456bcc04ae7fb8ce85c2a))
+
+
+* feat(s3_bucket_subscription)!: convert `bucket_arns` to set (#49) ([a13b8fd](https://github.com/observeinc/terraform-aws-lambda/commit/a13b8fd75c8f1e882da0d2869a39acd06930a9e0)), closes [#49](https://github.com/observeinc/terraform-aws-lambda/issues/49)
+
+
+### BREAKING CHANGES
+
+* migrating from previous versions may result in a race
+condition where terraform attempts to create a new
+`aws_s3_bucket_notification` prior to destroying the previous one.
+Re-running apply should successfully work around this issue.
