v0.7.2 — Feature gate postgres/server modules

What's Changed

Enables ares-server to compile as a lean library dependency via cargo add ares-server --no-default-features --features openai. This unlocks composable use from CLI agents like pawan.

Feature Gating

• sqlx is now an optional dep (only pulled in with postgres feature)
• api, auth, middleware, research, workflows modules gated behind postgres
• TenantDb, PostgresClient, AppState, base_router gated behind postgres
• agents::orchestrator and agents::tenant_agent gated behind postgres

Always Available (no postgres needed)

• ares::llm — LLMClient, Provider, ToolCoordinator, ProviderRegistry
• ares::tools — Tool trait, ToolRegistry, built-in tools
• ares::agents — Agent, ConfigurableAgent, LoopDetector, CheckpointManager, AgentRegistry
• ares::memory, ares::types, ares::utils, ares::models

Backward Compatibility

Zero behavior changes when postgres feature is enabled (default). All existing deployments compile and run identically.

Usage for Lean Library Consumers

[dependencies]
ares-server = { version = "0.7", default-features = false, features = ["openai"] }

Full changelog: v0.7.1...v0.7.2

v0.7.0 — OSS Split + ContextProvider + PostgreSQL

Breaking Changes

• PostgreSQL required — SQLite/libsql/Turso support removed. Use docker-compose.minimal.yml for quick PostgreSQL setup.
• ContextProvider trait — AppState now requires a context_provider field. Use NoOpContextProvider for default behavior.

New Features

• ContextProvider trait — pluggable external context injection into agent calls
• base_router() — composable entry point for building managed platforms on top of ARES
• Optional Eruka MCP tools — OSS gets 5 generic tools, managed deployments get 8
• Pre-commit hook + CI guard — blocks proprietary content in OSS repo
• docker-compose.minimal.yml — PostgreSQL-only for OSS developers
• mdBook docs — new "Extending ARES" section (ContextProvider + base_router)

Improvements

• 215 tests pass in 2 seconds (multi-threaded)
• connect_lazy for test DB pools (fixes tokio runtime deadlock)
• API key generation includes ares_ prefix
• Deploy handler uses env vars instead of hardcoded paths
• SVG logo (consistent with other DIRMACS projects)

Full Changelog

v0.6.2...v0.7.0

v0.5.0

Added

• Unified ToolCoordinator: Provider-agnostic multi-turn tool calling orchestration
  • New ToolCoordinator struct for managing tool calling across all LLM providers
  • ToolCallingConfig for configuring max iterations, parallel tool calls, and timeouts
  • ConversationMessage enum for unified message representation
  • New generate_with_tools_and_history() method added to LLMClient trait
  • Implemented for all 4 providers: OpenAI, Anthropic, Ollama, LlamaCpp
  • Location: src/llm/coordinator.rs

Deprecated

• OllamaToolCoordinator: Deprecated in favor of the new unified ToolCoordinator
  • The Ollama-specific coordinator still works but will be removed in a future version
  • Migrate to ToolCoordinator for cross-provider compatibility

Full Changelog

v0.4.0...v0.5.0

v0.4.0

What's New

Anthropic Claude API Provider

Full support for Claude models via the Anthropic API. Enable with the anthropic feature flag.

• Supports Claude 3.5 Sonnet, Claude 3 Opus, Haiku, and all Claude model variants
• Streaming support with tool calling
• Full LLMClient trait implementation

Token Usage Tracking

LLM responses now include token usage statistics (prompt_tokens, completion_tokens, total_tokens) across all providers.

Fixes

Windows MSVC Compatibility

• Added compile-time error for local-embeddings feature on Windows MSVC targets
• Prevents cryptic ort-sys linker errors by failing fast with a helpful message

Security

• Updated lru to 0.16.3 to fix RUSTSEC-2026-0002

Breaking Changes

full feature no longer includes local-embeddings

The local-embeddings feature has been removed from the full feature bundle due to ort-sys linker errors on Windows MSVC.

Migration:

• Windows users: Use remote embedding APIs or WSL
• Linux/macOS users: Use full-local-embeddings feature if you need local embeddings

New Feature Bundles

• full-local-embeddings - Full features with local embeddings (Linux/macOS only)
• full-ui-local-embeddings - Full features with UI and local embeddings (Linux/macOS only)

Installation

cargo install ares-server

Or with specific features:

cargo install ares-server --features "anthropic,openai,full"

v0.3.3

See CHANGELOG.md for details

v0.3.2 - Query Typo Correction & Embedding Cache

What's New

Query-Level Typo Correction

Fuzzy search now automatically corrects typos in search queries using vocabulary built from indexed documents.

• QueryCorrection struct for vocabulary-based word correction
• search_bm25_with_correction() and search_hybrid_with_correction() methods
• Uses Levenshtein distance for domain-specific corrections
• Closes GitHub issue #4

Embedding Cache

New in-memory LRU cache for embedding vectors to avoid re-computation.

• EmbeddingCache trait with get/set/invalidate/clear/stats methods
• LruEmbeddingCache with SHA-256 hashing, configurable max entries, optional TTL
• CachedEmbeddingService wrapper for transparent caching
• Thread-safe with parking_lot RwLock

Documentation Updates

• Updated KNOWN_ISSUES.md, DIR-24_RAG_IMPLEMENTATION_PLAN.md, FUTURE_ENHANCEMENTS.md
• Removed stale session log file
