+## Features
+
+- **Webhook Payload Consistency** - Webhook payloads now use the REST API v1 DTO format for consistent structure across integrations
+- **Channel Config Testing** - Webhook channel test endpoint now accepts the current config for live testing before saving
+
+## Improvements
+
+- **User Read Service** - Centralized user queries (ListAll, CountActive) into a dedicated service, reducing duplication across handlers, auth policy stats, and briefing scheduler
+- **ws CLI Paginated Responses** - Fixed workspace and milestone list commands to correctly parse paginated server responses
+- **ws CLI Non-Interactive Config** - `ws config init` now supports non-interactive mode when `--url` and `--token` flags are provided

+
+## Fixes
+
+- **SCIM Deactivation** - Fixed accidental user deactivation during SCIM provisioning
