All notable changes to ARES are documented here. This project follows Semantic Versioning.

0.6.3

Multi-provider LLM, tenant agents, and enterprise metering.

This release transforms ARES from a single-provider system into a full multi-provider LLM platform with enterprise-grade tenant management.

Added

• Multi-provider LLM routing — Support for 4 providers (Groq, Anthropic, NVIDIA DeepSeek, Ollama) and 11 models through a unified API.
• Model tier system — fast, balanced, powerful, deepseek, and local tiers with automatic provider routing.
• Tenant agent system — Agents stored in the database per tenant. Template-based provisioning with full CRUD via admin API.
• Agent templates — Seed templates applied automatically on startup. New tenants receive a default agent set.
• Usage metering — usage_events table, monthly_usage_cache, and daily_rate_limits for tracking tokens, requests, and costs per tenant.
• API key authentication — Authorization: Bearer ares_xxx on /v1/* routes with tenant scoping.
• Kasino enterprise agents — 4 specialized agent templates (kasino-classifier, kasino-risk, kasino-transaction, kasino-report) for the first enterprise client.
• Kasino API routes — Both JWT-protected (/api/kasino/*) and API-key (/v1/kasino/*) endpoints.
• Admin provisioning API — Atomic tenant creation: schema + agents + API key in a single operation.

Changed

• Chat handler now resolves tenant_id from authentication context instead of hardcoded values.
• Provider configuration moved from code to ares.toml for runtime flexibility.
• Rate limit enforcement now operates at both the provider and tenant level.

Fixed

• Chat handler tenant_id resolution for multi-tenant requests.

0.6.2

Streaming and SSE support.

Added

• Server-Sent Events streaming — POST /v1/chat/stream endpoint for real-time, token-by-token responses.
• Stream handler — Unified streaming across all providers with consistent SSE format.
• Context continuation — context_id parameter for maintaining conversation history across requests.

Changed

• Response format standardized to {"response", "agent", "context_id"} across all endpoints.

0.6.1

Tool calling and RAG foundations.

Added

• Tool calling framework — Define tools per agent. ARES manages the tool-call loop, execution, and response assembly.
• RAG pipeline — Retrieval-augmented generation with pluggable document stores.
• Workflow engine — Chain multiple agents into multi-step workflows with deterministic execution.

Changed

• Agent configuration schema extended to support tool definitions and RAG settings.

0.5.0

JWT authentication and user management.

Added

• User registration and login — POST /api/auth/register, POST /api/auth/login.
• JWT token lifecycle — 15-minute access tokens, refresh token rotation, logout/invalidation.
• Role-based access — User roles with permission checks on protected routes.
• Admin authentication — X-Admin-Secret header for internal administration endpoints.

Changed

• All /api/* routes now require JWT authentication.
• Error responses standardized with error and code fields.

0.4.0

PostgreSQL backend and multi-tenant schema.

Added

• PostgreSQL integration — Full migration from in-memory storage to PostgreSQL with sqlx.
• Auto-migration — sqlx::migrate!() runs on startup. No manual SQL required.
• Tenant schema — tenants, tenant_agents, and api_keys tables with foreign key relationships.
• Tenant tiers — Free, Dev, Pro, and Enterprise tiers with configurable limits.

Changed

• All state persistence moved from in-memory structures to PostgreSQL.
• Connection pooling via sqlx::PgPool with configurable pool size.
