+# Overview of the v1 API evolution
+
+The transition from `v1beta1` to `v1` for Scaleway Serverless Containers introduces significant improvements in security, resource management, and flexibility.
+While the transition is designed to be as smooth as possible, users of the API, CLI, and Terraform should note several key updates to field names and behaviors.
+
+The changes outlined in this document only concern Serverless Containers. The Serverless Functions and Serverless Jobs APIs remains the same.

+
+## Key improvements
+
+### Advanced Triggers and Cron management
+
+Triggers have been redesigned to offer more granular control over how your containers are invoked.
+
+* **Unified CRONs:** CRONs are now managed as a specific type of trigger. This simplifies resource management by using the `/triggers` route for all event sources.
+* **Custom HTTP paths and headers:** You can now specify a custom HTTP path (ex: `/my-trigger`) and custom headers for any trigger, providing better integration with your application logic.
+* **Self-managed credentials:** For SQS and NATS triggers, you must now provide your own IAM credentials. This improvement prevents accidental trigger failures caused by deleted system-generated credentials, and enables more flexibility (triggering a Scaleway container from SQS queue hosted on your Instance).
+
+### Automatic Deployment
+
+In the `v1` API, the `deploy = true` flag is no longer required. `CreateContainer` API calls and container updates will now automatically deploy the container immediately. This aligns Serverless Containers with the standard behavior of all other Scaleway products.
+
+### IAM Authentication
+
+JWT-based authentication is being gradually deprecated in favor of IAM credentials. The deprecation will be effective once IAM credentials provide the same granularity as JWTs. Refer to the [dedicated documentation](/serverless-functions/how-to/migrate-jwt-to-iam-authentication/) for more information.
+
+### Container Registry namespaces
+
+Creating a Serverless Containers namespace no longer creates a `funcscw` Container Registry namespace automatically.
+
+This change allows for greater control over the organization of Container Registry namespaces, and avoids quota errors when creating Container namespaces.
+
+### Health Checks
+
+In addition to health checks, we have introduced Startup Probes. They allow advanced users to define a specific check that runs only during the initial boot of the container, preventing the system from prematurely restarting slow-starting applications.
+
+## Breaking changes
+
+<Message type="warning">
+If you call the Scaleway Serverless Containers API directly via HTTP calls, you must pay attention to the following breaking changes.
+</Message>
+
+When using the product via higher level clients like [Scaleway Console](https://console.scaleway.com/), [CLI](https://github.com/scaleway/scaleway-cli), [SDK](https://www.scaleway.com/en/docs/scaleway-sdk/),
+[Terraform](https://registry.terraform.io/providers/scaleway/scaleway/latest/docs) the impacts will be minor.
+
