Changelog - Dialgen Documentation

This changelog provides a detailed overview of updates, new features, improvements, and bug fixes across different versions of Dialgen.

Version 1.3.0 (February 2026)

Indian language support: Voice agents can now speak and understand multiple Indian languages including Hindi, Tamil, Telugu, Bengali, Kannada, Malayalam, Marathi, Gujarati, Punjabi, Odia, and English India. To enable it, select Dial6 in Voice Configuration and choose your desired language from the Language dropdown; the same dial also lets you pick the voice persona.
Arabic language support: Added support for Arabic (Saudi Arabia dialect). Voice agents can now understand and respond in Saudi Arabic. To enable it, select Arabic from the language dropdown and choose your preferred voice persona.

API Path Refactoring: All private endpoints have been moved to the versioned /api/v1/ path for consistency and future-proofing.
- /api/private/call/dial → /api/v1/call/dial
- /api/private/call/get-metric → /api/v1/call/get-metric
Dual-Layer Status System: Introduced a high-performance live status system using memory cache (Redis) with a 30-day retention period.
- New endpoints for live tracking: GET /api/v1/status/call and GET /api/v1/status/batch.
New Management Endpoints:
- List All Batches: GET /api/v1/batch/list – View all campaigns associated with your account.
- Create Call Summary: POST /api/v1/call/create-summary – Manually trigger summary and metric generation.
- Cancel Batch: POST /api/v1/batch/cancel – Stop running or pending campaigns immediately.
- System Health: GET /api/v1/health – Monitor backend connectivity.
Persistent Status: Added GET /api/v1/call/check-status and GET /api/v1/batch/check-status for retrieving historical data after the 30-day live cache expires.
Enhanced Batch Monitoring: The check-status endpoint for batches now queries the database directly for accurate historical reporting and supports a limit parameter to control the number of recent calls returned.

Auth Transparency: Documentation now features highlighted <Info> callouts clearly explaining that userId should be passed in all requests. Added direct links to the API Keys dashboard for easier access.
Documentation Revamp: Updated all API reference pages to match the new versioned paths, added missing management endpoints, and enhanced monitoring workflows.
