Q4 2024

Added the Global RateLimit module you can use to set a limit on the number of HTTP and gRPC requests to a virtual host. You can set this limit for the entire virtual host or its individual route.

This feature is at the Preview stage. To access this feature, contact support.
You can now add your own HTTP status codes that backend health checks will treat as correct. Code values can range from 100 to 599.
Added an option of keeping a connection alive even if the health check fails. This option is only available for Stream checks.
Added an option to set an idle timeout for Stream and SNI listeners.
Added a description of the x_forwarded_for field that is provided in load balancer logs.

All new features are currently supported in the CLI, API, and Terraform interfaces.

Added validation of internal IPv4 addresses when creating or updating a load balancer.
Fixed the validation issue when creating and updating a target group that could place a backend without a specified weight in a group of backends with specified weights.

Improved stability of data processing and transmission (data plane) within the service.
Implemented integration with Yandex Smart Web Security:
- Connecting a virtual host to a security profile (management console, CLI, Terraform, API).
- Sending Smart Web Security event logs to a Yandex Cloud Logging log group.
- Sending Smart Web Security metrics to Yandex Monitoring.
Changed behavior of the load balancer with Stream backend groups: now connections to a backend will be closed if the backend fails a health check.
Optimized the process of working with the list of operations with service resources.
Added the ability to search for a load balancer in the management console by internal IP address.
Added the ability to granularly place load balancer nodes in different availability zones using the management console.
Improved the Terraform provider performance: eliminated the validation error when changing a load balancer listener's type from TLS to Stream and vice versa.
