# Changelog All notable changes to this project will be documented in this file. The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/). Each revision is versioned by the date of the revision. ## 2026-10-22 - Centralize route validation with error counts in blocked statuses and detailed diagnostics identifying possible config sources in debug-log. - Cleaned up the GatewayRouteState by removing the integrator mode sub-state. ## 2026-10-21 - Updated the home page to include two missing sections. ## 2026-10-19 - Moved the documentation tooling to the centrally managed `platform-engineering-documentation-files` Copier template and added a scheduled workflow that keeps it in sync. There is no change to the charm. ## 2026-10-07 - Add arm64 build for `gateway-route` ## 2026-09-29 ### Added - Added `haproxy-route-tcp` to modes of operation explanation page. - Added an explanation page for `haproxy-route-tcp` ## 2026-09-23 ### Added - Added `cache-inactive` and `cache-max-size` config options, published to content-cache over the `cache-config` relation to control cache eviction and total disk usage. ## 2026-09-22 ### Added - Explicitly block all units when more than one unit is requested. ### Fixed - Removed EndpointSlice cleanup logic for `gateway-route` (remnant from Integrator mode) which broke the backend services. ## 2026-09-2 ### Added - Added support for `strip-prefix` that is passed from the `ingress` relation. ## 2026-08-20 ### Added - Added the terraform release workflow that handles creation of tags when terraform files change. ### Fixed - Fixed the publish workflow to call the `canonical/charm-ci` publish reusable workflow instead of the integration-test workflow. ## 2026-07-21 ### Added - Added support for the `Strict-Transport-Security` (HSTS) response header on HTTPS `HTTPRoute`s. When HTTPS is enforced, the `hsts_max_age` value published by `gateway-api-integrator` is injected as an HSTS header via a `ResponseHeaderModifier` filter. ## 2026-07-20 ### Updated - Updated terraform module to allow deploying `ingress-configurator` with Juju provider 2.x. ## 2026-06-26 ### Fixed - Fixed a bug where multiple `gateway-route` relations with enforced HTTPS caused the gateway to become unreachable. The fix creates one HTTPS HTTPRoute and one HTTP HTTPRoute per hostname, each referencing its dedicated Gateway listener. ### Added - Added support IP based URL in `ingress` relation when integrated with `gateway-api-integrator` when no hostname is set. ### Removed - Removed support for config-driven (external) backends with `gateway-route`, as the use case that originally motivated this feature no longer exists. ## 2026-06-17 ### Added - Added support for `gateway-route` in adapter mode when the workload port is not open. ## 2026-06-01 ### Added - Added support for `gateway-route` relation in adapter mode. ## 2026-04-20 ### Added - Added config options `tcp-timeout-server`, `tcp-timeout-connect`, and `tcp-timeout-queue`. ## 2026-03-17 ### Added - Added support for NodePort routing for Kubernetes substrates when an ingress is integrated, overriding the old routing behavior where the ingress data was used for sending traffic upstream. ## 2026-01-22 ### Added - Add config options `tcp-enforce-tls`, `tcp-health-check-interval`, `tcp-health-check-rise` `tcp-health-check-fall`, `tcp-health-check-type`, `tcp-health-check-send`, `tcp-health-check-expect`, `tcp-health-check-db-user`. ## 2026-01-15 ### Added - Add config options `tcp-retry-count`, `tcp-retry-redispatch`, `tcp-load-balancing-algorithm`, `tcp-load-balancing-consistent-hashing`. - Fix bug where integrating with `haproxy-route-tcp` does not update the relation data. ## 2026-01-12 ### Added - Add external-grpc-port configuration to support gRPC traffic routing. ## 2025-11-25 ### Added - Added upgrade documentation. ## 2025-08-01 ### Changed - Add backend-protocol configuration option. ## 2025-07-21 ### Changed - Require interval, fall and rise health checks to either be all set or none ## 2025-07-14 ### Added - Add check-interval, check-rise, check-fall, check-path and check-port configurations ## 2025-07-10 ### Added - Add retry-count, retry-interval and retry-redispatch configurations ### Added - Add ingress integration support ## 2025-07-09 ### Added - Add path and subdomain configuration to the `ingress-configurator` charm.
