+# Differences of lambroll v0 and v1.
+
+See also issues and pull requests labeled `v1`.
+
+## Breaking changes
+
+- `lambroll archive` outputs zip binaries into the `function.zip` file instead of STDOUT. [#327](https://github.com/fujiwara/lambroll/pull/327)
+  - If you want to output to STDOUT like v1, use `lambroll archive --dest -`.
+- `lambroll diff` shows a short unified diff by default. [#328](https://github.com/fujiwara/lambroll/pull/328)
+  - `--no-unified` option outputs a long unified diff like v1.
+
+## New features
+
+- Add `status` command. [#336](https://github.com/fujiwara/lambroll/pull/336), [#344](https://github.com/fujiwara/lambroll/pull/344), [#349](https://github.com/fujiwara/lambroll/pull/349).
+  - `status` command shows the status of the Lambda function.
+- Add Lambda Function URLs features. [#330](https://github.com/fujiwara/lambroll/pull/330)
+  - See [README - Lambda Function URLs support](../README.md#lambda-function-urls-support).
+  - `deploy --function-url` option deploys a [Lambda funtion URLs](https://docs.aws.amazon.com/lambda/latest/dg/lambda-urls.html) related resources.
+  - Even if your Lambda function already has a Function URL, without `--function-url` option, `lambroll deploy` does not touch the Function URLs resources.
+  - `lambroll init --function-url` creates a file to deploy the Function URL related resources.
+- Add a SSM template function. [#319](https://github.com/fujiwara/lambroll/pull/319)
+  - `{{ ssm "/path/to/parameter" }}` is replaced with the value of the SSM parameter.
+- Add the `render` subcommand. [#326](https://github.com/fujiwara/lambroll/pull/326)
+  - `lambroll render` renders the function.json file and outputs to STDOUT.
+- Accept `LAMBROLL_*` environment variables as flag values. [#345](https://github.com/fujiwara/lambroll/pull/345)
+  - For example, `lambroll deploy --tfstate=s3://example/terraform.tfstate` is equivalent to `LAMBROLL_TFSTATE=s3://example/terraform.tfstate lambroll deploy`.
