Emissary Ingress and Ambassador Edge Stack

Note: Support for the deprecated v2alpha protocol_version has been removed from the AuthService and RateLimitService.

  • Feature: Added support for the Mapping AuthService setting auth_context_extensions, allowing supplying custom per-mapping information to external auth services (thanks, Giridhar Pathak!).
  • Feature: Added support in ambassador-agent for reporting Argo Rollouts and Argo Applications to Ambassador Cloud
  • Feature: The Ambassador Module configuration now supports the diagnostics.allow_non_local flag to expose admin UI internally only (#3074 -- thanks, Fabrice!)
  • Feature: Ambassador will now use the Envoy v3 API internally when the AMBASSADOR_ENVOY_API_VERSION environment variable is set to "V3". By default, Ambassador will continue to use the v2 API.
  • Feature: The Ambassador Agent is now available (and deployed by default) for the API Gateway (https://app.getambassador.io).
  • Feature: The Ambassador Module configuration now supports merge_slashes which tells Ambassador to merge adjacent slashes when performing route matching. For example, when true, a request with URL '//foo/' would match a Mapping with prefix '/foo/'.
  • Feature: Basic support for a subset of the Kubernetes Gateway API has been added.
  • Feature: Ambassador now supports the DD_ENTITY_ID environment variable to set the dd.internal.entity_id statistics tag on metrics generated when using DogStatsD.
  • Bugfix: Make Knative paths match on prefix instead of the entire path to better align to the Knative specification (#3224).
  • Bugfix: The endpoint routing resolver will now properly watch services that include a scheme.
  • Bugfix: Environment variable interpolation works again for ConsulResolver.Spec.Address without setting AMBASSADOR_LEGACY_MODE (#3182, #3317)
  • Bugfix: Endpoint routing will now detect endpoint changes when your service field includes .svc.cluster.local. (#3324)
  • Bugfix: Upgrade PyYAML to 5.4.1 (#3349)
  • Change: The Helm chart has been moved into this repo, in the charts/ambassador directory.
  • Change: The Mapping CRD has been modified so that kubectl get mappings now has a column for not just the source path-prefix (.spec.prefix), but the source host (.spec.host) too.
  • Change: The yaml in yaml/docs is now generated from the contents of the helm chart in the charts/ambassador directory.
  • Change: Support for the deprecated v2alpha protocol_version has been removed from the AuthService and RateLimitService.

Ambassador Edge Stack only

  • Feature: DevPortal: Added doc.display_name attribute to the Mapping CRD. This value allows for a custom name and documentation URL path of the service in the DevPortal.
  • Feature: DevPortal: Added naming_scheme enum to the DevPortal CRD. This enum controls the way services are displayed in the DevPortal. Supported values are namespace.name (current behavior) and name.prefix, which will use the Mapping name and Mapping prefix to display the services.
  • Feature: DevPortal: DEVPORTAL_DOCS_BASE_PATH environment variable makes the base path of service API documentation configurable.
  • Feature: DevPortal: DevPortal will now reload content on changes to Mapping and DevPortal resources.
  • Feature: DevPortal: DevPortal now supports a search endpoint at /docs/api/search
  • Feature: DevPortal search can be configured to only search over titles (with search.type=title-onlyin the DevPortal CRD) or to search over all content (search.type=all-content)
  • Feature: DevPortal search supports deep linking to openapi spec entries (must set search.type=all-content and search.enabled=true on the DevPortal CRD)
  • Feature: DevPortal: Trigger content refresh by hitting /docs/api/refreshContent
  • Feature: The AES ratelimit preview service now supports burst ratelimiting (aka token bucket ratelimiting).
  • Bugfix: The AES ratelimit preview no longer ignores LOCAL_CACHE_SIZE_IN_BYTES.
  • Bugfix: The AES ratelimit preview no longer ignores NEAR_LIMIT_RATIO.
  • Bugfix: The AES ratelimit preview no longer ignores EXPIRATION_JITTER_MAX_SECONDS.
  • Change: Silence DevPortal warnings when DevPortal cannot parse a hostname from a Mapping. (#3341)
